Additional Responsibilities Of A Reviewer?

Recently, I read an article that advised those who review things - To Not just review or mention the good products...But, that the reviewer should also inform his readers of the bad products, the ones to avoid. I suppose I've always been reluctant to do this...
- Instead -
I'll write a post (soon) which will simply list all of the bat detectors which are good value, good pieces of kit, and which I would recommend to anyone. In other words - A complete list of any & all detectors (in all price ranges) which are known to be excellent products; which any buyer would be more-than-pleased with. 
I could easily indicate exactly which detectors to avoid (and why) if I were inclined to do so. But, I'm not. I will simply leave the bad ones off the list.

So, if you are considering the purchase of a bat detector; and the one you had in mind is not on the list: Avoid it!

Review: Kaleidoscope Pro Software From Wildlife Acoustics Part 1 Of 2

Review: Kaleidoscope Pro Software From Wildlife Acoustics. Part 1 Of 2

First, I must apologize: This review should've been posted much sooner. I was away from home recently, searching for "battier pastures"... I forgot to pack my laptop's A/C adapter. So, I was unable to share all of the great screen captures I'd originally prepared. 

If you are interested in an automatic bat call identification package - Then I urge you to download the free 15-day trial of Kaleidoscope Pro. You get to try out the full version of this software for 15 days, which will give you an opportunity to fully test drive the package before you buy. Just to clarify: This is a fully-functioning trial version - Nothing is disabled or limited, as in other software trial downloads. As I'm sure many of you already know, this is not a common practice. Most of the time, trial versions of software applications are severely limited.

The offer from Wildlife Acoustics has recently been extended - The free trial download will be available until June 30th 2013.

Again, I urge you to visit the Page - Check out the amazing screen shots! Watch the video presentation by Guest Speaker David Riggs, etc. There is a lot to see and learn there! Especially, if you're considering the purchase of a license.

I have tested this application, and found it to be excellent in overall performance. As per the Wildlife Acoustics' Kaleidoscope Pro page: "Today we offer classifiers for 21 species of North American bats and 10 for the U.K.."
This is very impressive. I have compared it, to all of the other Auto Bat Call ID software packages; Including SonoBat. And, frankly it is one of the two best applications I have found. The other, being BCID.

Which is better?

In regards to features, performance, and ease of use: Kaleidoscope Pro is clearly "smoother around the edges" (more refined, etc.) than the other currently available packages out there.
Kaleidoscope Pro is clearly the winner between the two.

Kaleidoscope Pro currently retails for $1,499.00 (U.S. Dollars)
BCID's current price is $979.00 (U.S. Dollars)

Something else that is interesting, is that - In many ways, the two are somewhat similar: Both in the way they look, and the way they work. Which brings us to the next question; how does it look? Below is a screen capture of the first dialog box you see upon launching Kaleidoscope Pro.
By default, it opens up as a medium-sized dialog box. Here is a full view, enlarged (maximized Window) for a better look:

Kaleidoscope Pro Ver. 1.1.3

Here is a quick screen shot, of one of tonight's recordings (picked up with the new Avisoft USG 116Hnm) - Lots of color variations are possible, they are easily changed using slider controls:

 Evening Bat (Nycticeius humeralis)

At this point, I should probably re-iterate something here - For those who haven't seen my recent review of BCID software (from Bat Call Identification, Inc.) and that is - In the realm of automatic bat call identification software:
There are currently only two software packages that warrant consideration for purchase:

Kaleidoscope Pro -and- BCID.

There is also a third. I list and describe it separately here, since it is a free application. It is awesome; and works beautifully with The Batlogger series of bat detectors (from Elekon).
It is BatExplorer from Elekon AG. The good news, is it's free. The bad news is that:
American bat species are not currently included.

In summary:

Kaleidoscope Pro is a comprehensive, very well-made, software application. It also seems to have a bright future, with various advancements already planned...Frankly, I can't keep up with all the neat additions they've been making! Which is why this is going to be a two-Part post.

BCID gets the job done, almost as well. But, leaves some things to be desired. And, may even be considered to be lacking in a few (minor) areas.

BatExplorer works absolutely beautifully - With two caveats: 1. You must be using files produced by a Batlogger detector: In order for everything to work quickly, smoothly, and with the minimal number of mouse clicks -and-  2. No American bat species are covered.

The three companies listed above, are each very knowledgeable and dynamic. They pay attention to exactly what is needed by Bat Workers in the field; and do their best to tailor their software to suit their various needs. Wildlife Acoustics is chief among these. In regards to my use of the term 'Bat Workers' here - You may take this to include: Bat Biologists, Researchers, PhD's and soon-to-be PhD's. And generally anyone who works with these incredible mammals.

I have only reached these conclusions, after a lot of careful research. After studying user manuals, specifications, numerous field reports, other reviews (from those with more field experience than I), and a lot of correspondence with several Bat Working Professionals.

In other words, all other currently available bat call identification software has been thoroughly scrutinized by yours truly. 

EchoClass - Although free, is hardly good enough to be considered for any serious (accurate) results, etc. No technical support
SonoBat - Doesn't have a good "track record" or substantial following among bat workers. 
What I've learned from other owners, is that End User support leaves much to be desired.
For (one) example - In the recent past, I e-mailed almost a half-dozen questions (to SonoBat) that all went unanswered. Others have reported the same thing. This basically translates to - No technical support.

The Brand-New UltraSoundGate 116Hnm From Avisoft Bioacoustics

I'm very happy to report, that I've been given the opportunity to test and review the very latest ultrasonic device from Avisoft Bioacoustics - UltraSoundGate 116Hnm

 

 

 

 

 

 

 

The unit arrived earlier today. Wow! The device is ultra-compact, and very cool-looking! I've already finished reviewing all of the currently available documentation for it - This device will be serious competition for the other micro-sized, high-tech, super detectors on the horizon... 

 

There will also be an even smaller, Black Edition (Bk): Which will feature sampling rates of 750, 500, and 375 kHz - Amazing! The only other bat recording device that I can think of, featuring such a high sample rate is the Pettersson D1000X (at 768 kHz). 

Unit pictured below, with a CF Memory card for size reference (includes a unique USB cable) 


I'm looking forward to reviewing it!

Happy bat detecting!

An Upcoming Post...Will Feature The Best Bat Detectors!

It is May 6th, 2013 and bat detecting season is upon us in the Northern hemisphere of the World. For some reason, I feel compelled, even obligated, to state exactly what the best bat detector models are.

As I stated in a recent blog entry, an upcoming post will feature The Best bat detectors!
It will be entitled 'The Best Of The Best Bat Detectors'

It's time to leave some of the mystery behind...
It's time to take the guesswork out of the decision process...
I'll be addressing a very popular question: "Which is the best bat detector for my budget?"
I will not be utilizing any colourful charts. Although, I'll admit - That even I enjoy some of those comparison charts from time to time...

I will be listing the best bat detectors, in each of the following three major price categories: $2k-$2500, $1k-$1,500 and $150-$500 (U.S. Dollars) - Although I'll probably list prices in other major currencies (listing prices in Euros, and U.K. Pounds as well).

Happy bat detecting!

The Need For Un-biased, Bat Detector Review Blogs

It recently occurred to me, that when I first started this blog, there weren't many like it out there. 
There seemed to be a need for an honest, un-biased, bat detector review blog - One that was almost all-inclusive. Something concise and detailed - Which included (or aspired to include) all of the different bat detectors from all around the World.

So, I'd like to make something else clear - Just because I haven't had the opportunity to perform a hands-on test and review of a particular bat detector - Does not mean that I haven't researched it extensively. There are several well-known/World-class instruments which may not be featured. Please don't presume that I've neglected to research a particular bat detector, simply because a full, detailed review doesn't appear on this blog.

The fact is, that I carefully study all of the currently available documentation for just about each bat detecting device in existence. The only exceptions, being the devices that don't have any detailed documentation available. For example - A device such as the Nanobat: There is really only one page of documentation available; a PDF Here.

There is practically no bat detector out there, that is too "minor", too remote, or too obscure for me to overlook...
What I mean by "studying" documentation, most times translates into reading a full 250 to 500 pages. Which typically include: Manufacturer Specifications, User Manual, Case studies, Field reports from Professional Bat Workers/Researchers, Comparisons/Findings made during past (and recent) Surveys, etc. Many of these documents are written by PhD.'s. Most are difficult to find and/or obtain. But, again, for me: It's just what I do - A labour of love.
Again, the point of all this, is just to illustrate how thorough I am when it comes to bat detector research. I consider myself dedicated and persistent, and it probably helps to have a healthy obsession with bat detectors.

So, You CAN Afford Auto Bat Call ID Software? Which One To Get?

A few Posts ago, there was one titled 'So, you can't afford Auto Bat Call IDing software?'

Here is my version of a follow-up post. I'll call it:
'So, you CAN afford auto bat call ID software?' ...Which one should you get?

Where shall we begin? I'll give you a cliff notes version: Well, for starters - For those who aren't very familiar with computer software in general - I'd like to point out that bat call identification software is particularly difficult to produce well. There is a lot of work required, to make an effective product. The myriad of special algorithms required alone, can be overwhelming.

That is one reason why it's not easy to find a well-executed, robust, and easy-to-use package. Also, one of the reasons why it's never cheap! Here, we will cover the latest and greatest bat call ID software packages available today.

Each company producing Bat call analysis software has their own priorities, when it comes to which bats will be covered. In other words: Will the application focus primarily on bats from the USA? UK? Europe? There are several software packages that either:

• Handle both (i.e. USA and UK/Europe)

• Have one complete, and are working on adding bat species of the other (side of The Atlantic Ocean) 

In any case, there's really no need to elaborate on any of the other applications. What most Folks want to know, is which one is worth investing in? Which one is the best?

So, I did a lot of reading (of existing documentation, etc.). After extensive, and concentrated study of: Documentation, case studies, research papers, and professional field reports, from all of the currently available Call ID software packages:

Listed below, in no particular order, are the two best software applications available today, for automatic ID of bat species: 

Kaleidoscope from Wildlife Acoustics

-And- 

BCID from Bat Call Identification Inc.

 
It's as simple as that.

In addition, I have personally extensively tested, and reviewed each of these software packages (substantial testing, evaluation, and comparisons were made; before I reached my conclusion). The two-part review of BCID software can be seen here: Part 1, Part 2

My detailed review, of the current version of Kaleidoscope Pro is still in process, but will also be posted here soon. For now, I'll say that:  
1. I've seen it routinely process almost 200 recordings in 12 seconds! 
2. There are all kinds of wonderful features being implemented into the software, even as I type. Features, that I cannot share yet; but will be sure to impress!

Now, there is one more, which happens to be both excellent and free! The only drawback, is that American bat species are not covered (at this time).

It is BatExplorer from Elekon, AG. I am currently testing this package, and I find it to be absolutely wonderful (a review will also be posted here, in the near future).

Honorable Mention:

The following software applications do not offer automatic bat species identification, but they are very good at what they do. Which is to enable a user to view recorded ultrasounds.

BatSound

BatScan

SeaWave

Soundchaser

 

In summary: If you intend on purchasing a software package, to automatically identify bat species from your ultrasound recordings - The only bat call ID packages that you should be considering, are: Kaleidoscope Pro, and BCID. 
If you are using a Batlogger, from Elekon AG - Then, you only need to download and install the free BatExplorer software, and you're done.

Review: The Batlogger M From Elekon Part 2 Of 2

Part 2 of 2 Review of The Batlogger M from Elekon

When a new bat detector arrives for me to review: One of the main things, that I always look for, is it's ability to detect bats at good distances. It just happens to be one of my major interests, as far as performance goes. It always has been my favorite "yardstick" in measuring performance. In years past, I didn't have access to the excellent locations that I do now (some excellent habitats are among them). Therefore, the majority of my bat detecting was done from home - a passive (overnight) monitoring situation. So, the ability to pick up bats at greater and greater distances became important to me.
And, I suppose old habits are hard to break... The point is, The Batlogger M is able to detect and record bats, from greater distances than any other device I've ever tested.
It's as simple as that. And I am well pleased. The interesting thing, is that at the same time - The unit will not record non-bat sounds. What we're discussing here, is a very unique instrument. I'd like to share a link; for those who enjoy reading more detailed/technical info. There are excellent graphs and explanations, of how just some of the features work: Batlogger M FAQ

In a side-by-side comparison, with the AnaBat SD2: During the course of one evening - The Batlogger M consistently picked up and recorded bat calls, while the AnaBat did not. These bats were at a distance of over 45 Meters, in this particular case. I believe these results are very telling!

Another major feature, that is amazing in and of itself - Is the built-in GPS. In a word? Wow.
I realize, that some view the GPS feature as unnecessary (especially well-experienced Bat Workers). But, I believe that generally, most appreciate having the feature. In the case of the Batlogger M, it really integrates very well. The GPS is efficient, and very precise. I quickly found out just how accurate the unit is: When I noticed that it basically "knew" which room of my home I was in! In addition, there is a integrated feature that knows which direction the Batlogger was pointed in, at the time of a bat pass. An electronic compass. Not only does this help make transects and other surveys extremely accurate; but it opens up additional possibilities (for future advances). You can get a glimpse of just what it's capable of, when working with Elekon's BatExplorer software (more on that in a separate post). 

Some things that I like:

• It is comfortable to hold for long periods of time (Bat Walks, Surveys, Transects) 
• The position of the microphone.
• Front-mounted speaker provides plenty of clear audio.
• The SD card is easily accessed - No screws, doors, latches, etc.
• There are 5 different Trigger Modes to choose from.

There is the Standard (default) microphone
There is the Ultrasonic microphone FG Black 
There is the Extension Kit which includes the FG Green microphone

The best part, is that Roger Jones and Sally-Ann Hurry (in The UK) will be posting their findings in regards to these unique microphones, on Roger's blog in the future.  
I'm really looking forward to it!  Not only are they experts on the Batlogger detectors, but they have also been instrumental in getting some features and developments in place on the system. Keeping the communication flowing with Elekon.



Some things that I'd change:

• I would like the unit to have a Date & Time feature that is un-affected (not corrected) by the built-in GPS. Currently, if the GPS is active - It will sync time by satellite. Some may welcome this feature (I don't)
• Although the microphone is robust, and fairly impervious to all but exposure to water - I would still like to see a bit of foam (such as a tiny windscreen) just for added protection.

Well, although this is Part 2 Of 2 of the Review. I have a feeling that I'll be re-visiting this detector here again soon. Indeed...even as I type this, I realize there may be some things that I've missed... I'll also be completing a review of Elekon's free BatExplorer software.
And a few other things... 

Happy bat detecting!

Review: The Batlogger M From Elekon Part 1 Of 2

I've been trying to keep my reviews a bit shorter; whenever possible. With some new bat detectors - There are simply too many features to effectively cover on just one, long page. The new Batlogger M is an example, of such an instrument. Like other high-end ultrasonic recorders: It has a lot of features! I could easily write a review that would end up being 4 posts long...Don't worry! I won't! ...But, I feel that there will be a need to "revisit" this detector in the future - Beyond Part 2. This has usually been the case with what may be called the "Alpha" detectors; examples would be: The BatBox Griffin, The Pettersson D240X and even The AnaBat SD2.

In this, Part 1 (of 2) of the review, I'll be focusing on the main attributes and features of the Batlogger M. Here is a Link to some of the most relevant features.

The Batlogger M arrived here in the U.S., very quickly, and well packaged. As you can see, from photos: The unit comes equipped with a lot of extras, as standard accessories (these will be addressed later). Including a great, foam-lined, custom carry case. The Batlogger M fits in the case like a glove. And, it provides an ample amount of protection. The other neat thing about it, is that there's also a bit of extra space in the foam-lined case. I've found it useful for things like: A small weather meter, microphone extension cable, and a small notebook. 

I found a very well-made/fully shielded (Kumo brand) microphone extension cable on Amazon. The addition of this cable makes the unit even more versatile; and I highly recommend getting one.
Elekon even offers one on their Web site Here.

The next factor that becomes apparent, is the size and shape of the Batlogger itself: It's not square! Yes, someone was "Thinking outside the box" on this one! It's hourglass shape fits very comfortably in the hand (their Batscanner sports the same shape, by the way). At 350 Grams, it's not too heavy either.
I also like the built-on, frame of rubber armoring, it provides a positive grip in the hand. It also seems to offer a bit of protection from the occasional accidental bump, etc. It features a very accurate, built-in GPS system (more on that in Part 2).
  
In addition, when the unit is updated to the latest firmware (Version 2.2) - It's ultrasonic pick-up range expands. It's able to tune all the way down to 2kHz (on the low end) and up to 155kHz (on the high end). The previous firmware version only went down to 15kHz, and up to 150kHz.
This is excellent for singing insect recordists - like myself! Now, one may specifically target many species of singing insects. For example: It can be set for: 2kHz - 25kHz when I'm after cricket and katydid recordings. But, for a more relevant example, the unit can be set for: 15kHz - 65kHz Which is how I keep the test unit set (for my local bats).

Offering the ability to update firmware on a high end bat recorder is wonderful - Because the manufacturer can always add some great new features!
  
I believe that this may be the best handheld bat detector I've ever had the pleasure of reviewing. I realize this is very high praise. Especially when you consider the World class instruments that I've been fortunate enough to test and review over the years...The reason why I can make such a statement, is: The Batlogger M is sensitive beyond belief - The range at which it can detect and record bats is unprecedented. Yet, at the same time, is almost impervious to man-made and other unwanted noises. So far, I have estimated the "pick-up" range of the unit, and it is often over 50 meters.
Also: The Batlogger M, with it's simple Menu system, is an absolute pleasure to use. It has all the features one would desire in a bat recorder (and none of the useless ones). It also produces excellent sonograms, as good as those produced by instruments costing thousands of dollars more. 
The other (somewhat reassuring) factor is, there are other very experienced individuals (Bat Workers, Professionals, and others) - Who have reviewed the Batlogger M, and have come to similar conclusions. There are a couple of fairly well-known Professionals who have chosen it to be their primary bat detector - The only detector they use. They also happen to be Friends of mine. For excellent reviews on The Batlogger series of detectors, as well as The Batscanner, see the Blog of Roger Jones. To get an idea of how successful bat surveys and emergence counts have been performed using The Batlogger, see the Site of Jon Whitehurst. 
And, they are not the only ones...

This bat detecting system is particularly well-suited for unattended monitoring/recording of bat activity. It's proven to be really excellent for my nightly recordings; during this test period. The included AC power adapter, effectively removes any concern of running out of battery power (if you have access to a mains power outlet). While on the subject of power: I really like the fact, that the unit is powered by a built-in, Li-Ion battery (3.7V 4600mAh). No AA's to re-charge!
I've kept the unit On/Monitoring for ~12 hours each night. I have found it to go almost 4 nights, before needing a re-charge.

I'm very fond of the display on the Batlogger M; and the way it constantly changes and updates it's current status. While detecting bats, it is calculating/indicating the peak frequency. It then displays the peak frequency of the last bat call recorded. Very nice! It's undoubtedly, the most aesthetically pleasing display I've seen, since the BatBox Griffin. Yes, I'll say it: It looks really cool! The brightness is also fully adjustable. Some additional Pro's and Con's: 

Pros:

• Built-in Li-ion battery, provides long up-time even in low temperatures.
• Incredible sensitivity / Able to create good recordings of bats at great distances.
• The most pertinent information is constantly displayed.

Cons:

• The stock microphone is not weather or waterproof. Although, Elekon does offer two models of (optional) microphones that are (details in Part 2). 

The second Part will cover topics such as: How well it records bats, a summary of a typical workflow, a synopsis of how it compares to other high-end recording devices (in it's price range), and the quality of the bat calls recorded. Sonograms will be posted. And, I also hope to include sound recordings of bat passes; as they are reproduced by the built-in speaker.



 
Happy bat detecting!
