Review: The BatLure From Apodemus Part 2 Of 2

Review: The BatLure From Apodemus Part 2 Of 2

After unpacking The Batlure, and installing batteries, it's time to copy recorded bat calls onto the SD memory card provided. The 4GB SD memory card, included with The BatLure already has high-quality recordings on it. They are high-quality recordings of European bat species. However, these were not useful to me, since none of them were of North American bats.

Time-expanded recordings (x10, preferably) are probably the most convenient type of bat call to use. Followed by, full-spectrum recorded files (which I used quite a few of).

Now that 8 fresh AA-size batteries are installed, along with the SD memory card (containing recordings of your preferred bat species); you are ready to power-upThe BatLure. The BatLure is fully, easily useable in the dark: The few buttons it has, are very easy to locate; due to their convenient locations (and the accompanying white markings).

The BatLure is controlled by a (very short) text file, called batlureconfig.txt. The standard/default copy of this file is already on the (root) SD card, when it arrives:

; batlureconfig.txt
; Apodemus BatLure
; This is a config file for your BatLure device.
; To have a fresh copy of this file, simply delete or rename this one, and restart the BatLure.
; It will create a fresh file with factory standard settings for you!
; Recorded files from Michel Barataud (http://ecologieacoustique.fr/) and Guido Pfalzer.

time_expansion    1        ;enable or disable time expanded files
track_pause    3             ;seconds pause between tracks
startup_volume    20       ;startup volume level, 0 to 40
repeat        1                  ;amount of times a wave file will be repeated when play time is lower than repeat time
repeat_time    0              ;repeat time, when the length of a wave file in seconds is lower than this time, it will be repeated

 The Batlureconfig file, represented in Courier font

So, when you press the Power button, the unit will begin to play the bat calls from the SD card.

The volume is set at 20 decibels, by default (this happens to be exactly in the middle). And is a good starting point.

The unit performs very well, without any issues to report. I went from not having any bat activity, to now having regular bat activity in my immediate area - It happened rather quickly. And, I firmly believe it was from the use of The BatLure. 
I may also be re-visiting The BatLure, with an addendum post here in the future. I plan to test The BatLure in both open/cluttered woodland areas, near ponds and lakes, and other environments. Until then...

Happy bat detecting! calling!

Review: The BatLure From Apodemus Part 1 Of 2

The BatLure, from Apodemus in The Netherlands, is an ultrasonic acoustic lure. It's primary purpose, is to playback recordings of bats; in full ultrasonic fashion. That is to say, it accurately reproduces (plays back) the unique ultrasounds of (recorded) bat calls. Such a device is of paramount importance, in one's effort to attract bats.
This cannot be properly accomplished without the existence of specially designed hardware (especially the speaker), such as the one employed in The BatLure.

There are several types and brands of these machines currently available. Some are more expensive than The BatLure, others are slightly less. However, that old cliche (that everyone is probably tired of hearing) bears repeating here: "You get what you pay for"
I came across a small advertisement (online) for The BatLure (while browsing bat detecting equipment). And I was impressed, as well as intrigued. 
After it's arrival, I was also fascinated by the excellent design and build-quality of the device.
In addition, I was even fascinated with the very nice carry bag it is supplied with:

The carry case, complete with separate pockets for fresh/unused memory cards and used memory cards.

For those interested in recording bats, most notably, Professionals: The prospect of being able to lure specific species to your location, can make the difference between the success or failure of a given Project or Study. 
When you really stop to think about it, the list of potential owners would actually be quite long... Those who would benefit from The BatLure include: Bat Researchers, Educators, Universities, PhD's-in-progress, Bat Workers (performing Surveys or otherwise), those interested in attracting bats to roost areas/Bat Boxes, other Pros involved with Wildlife, and even bat detecting enthusiasts...
The Manufacturer of The BatLure has provided their own list of potential uses:

• The luring of bats using recordings of bat social- and echolocation calls in order to catch them for research purposes;
• To draw the attention of bats to a new potential roost to hasten its colonisation. For example: bat boxes, newly constructed hibernacula as well as new summer- and maternity-roosts;
• The playback of bat calls during training and bat-detector courses;
• The testing of bat detectors and sound recording devices;
• The localization of mating roosts via playback of male song/vocalizations and observation of responding territorial males.

As with several other creatures in The Animal Kingdom, bats may be attracted to an area, by accurately reproducing their calls (essentially calling them in). The unique challenge with bat calls, of course, is that they are ultrasonic (and therefore inaudible to us). There is also a bit of a challenge, when endeavoring to reproduce calls of bats. The average/typical speaker is incapable of properly reproducing the ultrasonic calls of bats. This is where a device such as The BatLure is indispensable. 

 One of the many compartments of the BatLure's carry case, with pockets for fresh batteries and used/flat batteries.

This is the first time that I've had the opportunity to review such a device. And, I have been very impressed. Being fortunate enough, to have had extensive exposure to bat detecting equipment, I can tell you that the build quality of this unit is splendid.
Further information, Price, and technical specifications may be seen Here.

In the case of The BatLure - The hardware practically takes care of itself.
The only buttons/controls are: On/Off button, Volume Up(+), and Volume Down (-). 
By all means, those who are interested, may see the User Manual (in PDF format) Here.

The basic design of The BatLure, is that it's compact and solid. It sports a weather resistant and robust Aluminum enclosure. Unlike similar machines on the market, the speaker on The BatLure, has been afforded some protection by the outer ring. This helps prevent accidental damage to the speaker. And is comforting to have on a valuable piece of equipment.

The unit is very easy to use. The only process which requires some effort, is getting the calls of (the desired species) onto the SD memory card. A 4GB Class 4 SD memory card is included, with the BatLure kit. I've successfully used bat calls (.wav files) which were recorded using both full-spectrum, and Time-Expansion methods.

The (extremely simple) software which runs/controls The BatLure is a (very short) text file. For those who  have been around PC technology long enough: Think of a .bat/Batch file, Config-type file; or an .ini file. In the case of The BatLure, it is a .txt file called batlureconfig.txt.
More details on these subjects, will be covered in Part 2 Of 2; where I will also discuss:

• Typical workflow / Set-up.
• Variables
• Performance

The BatLure From Apodemus Has Arrived! First Impressions Part 2

This is The BatLure (from Apodemus) - And this is Part 2 of my initial impressions (further un-packing). So far, while compiling Part 1 of this Post: I was even impressed by the cartons which the BatLure and the optional Powerkit were provided in.
The fact is, there are manufacturers who also provide their products in attractive packaging.
Just one example which immediately comes to mind, is The Griffon, from BatBox. And, of course, there are others. 

The BatLure

The diverse, complete contents of the Powerkit - Wow!

A view of the BatLure's special speaker, with protective cap removed

The BatLure's optional Powerkit, includes components and (high-quality) power leads. Any and every possible power option has been addressed. Any power source that a user may think of has been covered. I was especially fascinated with: The option to use an automobile battery, and the cabled Timer apparatus.

Indeed, there is also a high-quality Timer included (pictured to the right of the unit, in above photo). Power plug adapters are also included, so that the A/C  power adapter may be utilized in any part of the World. With this optional Powerkit, you will never run out of interesting methods for powering your BatLure. Of course, these options are all very relevant and practical to those Bat Workers and Researchers working in very remote locations.

Amoung other things, The BatLure is provided with a 4GB SD memory card (more details on it later). Since it comes pre-loaded with (excellent quality) calls from European bat species - I am in the process of preparing my own recorded bat calls; from North American species for transfer to the memory card. I hope to perform the first real test of The BatLure, early this evening.

We are indeed in the "busy season" for bat detecting. As many of the bats are slowly beginning to awaken from their hibernation, etc., several bat detectors (and related things) are becoming available. For example, as I type this - I await the delivery of another new bat detecting system. One that will revolutionize the way we detect and record bats. And, it will be here before nightfall today. I'll keep you guessing, just until then!

Happy bat detecting!

The BatLure From Apodemus Has Arrived! First Impressions Part 1

I am pleased to announce the arrival of The BatLure kit, for testing and review. The BatLure and a Powerkit were delivered to me (here in The U.S.) from Apodemus in The Netherlands.

It was well packed, and the actual product boxes are interesting as well. So, this Unpacking & First Impressions Post will be in 2 Parts.

Under the packing material, the attractive product box

(the Powerkit is on the upper right) 

The carton containing The BatLure features some charming images; as well as having the Contents of the box printed on it (just below the title). Excellent.

Inside the BatLure's box, the unit is packed within the included protective case:

The handsome, padded nylon bag offers adequate protection for this first-class device.

This initial un-boxing and First Impressions Post, will be directly followed by Part 2...
