Review: The SSF BAT3 Bat Detector by MeKV (Germany)

Review: The SSF BAT3 by MeKV, sold by All About Bats (in Germany).

The BAT3 is full-featured heterodyne bat detector.

So, firstly: If you reside in Germany, Switzerland, or Europe in general - You might be interested to know, that ordering one of these detectors is a fast & easy process. And if you're in Germany or Switzerland, you are allowed to order it with the official battery.

Product Description - The SSF BAT3 is made by the same folks who manufacture The SSF BAT2, which is a well-known bat detector - which I reviewed Here (on this blog).

Packaging - I ordered The SSF BAT3, with all the options; and it all arrived to me here (in The U.S.) well-packaged, in ~2 weeks after ordering. I ordered mine from all-about-bats.net (in Germany), but they are also available from Veldshop (in the Netherlands).

For anyone ordering one of these units: 

• If you live on the East coast of North America, you can expect the delivery to take approximately 8-14 business days (not counting Sundays).
• If you live in Europe, you'll only wait a fraction of that time - Probably about 3 days, would be my guess (mostly likely as short as 1-2 days!).

Via DHL from Germany to The U.S.

Unboxing...Black Nylon carry case (w/ belt loop); the

included user manual is in the German language.

4GB MicroSD card, USB cable, European AC power adapter

The BAT3 wrapped in protective wrap.

This unit is small! And this happens to be one of the things which I really like about it. It's also very lightweight (125 grams).

Look how small and cute it is!

The (optional) carry case features a belt loop, and very secure Velcro® flap.

The unit is provided with: The attached, adjustable wrist strap; a full printed manual in German. I had printed out the English version of it (even before it arrived!)

The SSF BAT3 - All About Bats (English)

I've been able to find The SSF BAT3 for sale from two online dealers:

All-About-Bats (in Germany)

-and-

Veldshop (in the Netherlands)

As already stated, The SSF BAT3 is an active, heterodyne bat detector. It may be used as a tuneable heterodyne, or as an Auto Heterodyne (AKA the "Auto Bat" feature).

From the beginning, it's hard not to like this detector! Upon powering up and checking/testing this instrument: You will notice the incredible sensitivity and range; as well as the precision of it's volume control. These are the two main features which I noticed first.

The microphone utilized is the small electret model # FG-23629, made by Knowles.

I really like it's features! This bat detector is also fairly easy to use.
Of course, you have full control of tuning the heterodyne portion of the unit, via the Up and Down arrow buttons on the front (in 1kHz steps).

First impressions were good! The frequency range of this unit, is 15 to 150kHz. I really liked the sensitivity of the unit, and the audio output of the speaker is very good: Plenty of audio for everyone to hear on a bat walk.

The SSF BAT3 is a factory-assembled, ready-to-use detector. So, I got to charging the battery immediately. 

Note: Again, if you live outside of Europe, you will need to purchase your (Nokia-compatible battery separately).

The typical battery life is stated as being about 3-6 hours. Initial charge time for the new battery (before 1st use) was stated as 8 hours in the user manual. I was able to achieve full charge in about half that time...

(I have mine set to English).

When I went to insert the micro SD card, the little metal door came right off in my fingers - Yikes! I got it back on it's hinges, and locked the SD card in place. 

It has a few neat little informative "pages" (screens) about bats, bat calls, sonograms, etc., - Like a "micro encyclopedia" (for lack of a better description). I'll share pics of these screens below. It's available for viewing in both the German or English language. Something to look at during lulls in bat activity.

Just a couple of examples shown above

All in all, I like it. Mainly because it packs so many features into such a tiny package. Having purchased the belt loop carrying case, means it's easy to have with you, if you expect to be anywhere near bats.

With 2 button pushes to power on, it's very easy to use. Requiring the user to press two separate buttons in succession, prevents accidental powering on.

This little heterodyne detector would be ideal for beginner or intermediate bat chasers.
It would be an excellent choice for anyone leading a bat walk; and does produce nice sounding heterodyne audio.

Short videos of The SSF BAT3 may be seen on my YouTube channel.

I found this unit to be fairly accurate in what it detected, and the resulting spectrograms were very good. I would occasionally print them out, on 8.5x11" Letter size paper: The spectrograms look good, and you can write your own notes on the printouts. Either of the ("print screen") styles shown below, may be copied/pasted/e-mailed or sent directly to your printer.

While using The BAT3Viewer App, you can toggle between 3 color choices for ths spectrogram legend: Blue(s) as shown below, Green(s), and Red(s).

Pros:

• Uses a nice, sensitive, electret microphone element. It seems to perform as well as some other pro-level detector microphones. 
• It's tiny! If someone were in the market for a James Bond-sized/secret/full featured bat detector, this would be it.
• It has the potential to be plenty loud - enough audio, even for a large-sized group to hear on a bat walk.
• It has a built-in torch - white LED. Which features an auto shut-off (I would have liked it a little brighter).

Cons: 

• It seems to be based on a Nokia cell phone platform. It's not very robust, in fact I might describe it as closer to delicate.
• The included wrist strap would be a must! If you drop it on a hard surface, damage will occur.
• It's only a heterodyne detector, although it does have an Auto-Het tuning feature.
• The door which holds the micro SD card, is the most delicate one I've ever encountered. Use caution.

Like The SSF BAT2, the unit covertly uses a built-in Frequency Division circuit to produce spectrograms.

All things considered, it is a very nice heterodyne bat detector, with useful features. If I discover any other information or notes to add, I will update this review as needed.

The next bat detector to be reviewed here, will be The Teensybat 4.1 (DIY) Kit; which comes to us from The Netherlands. 

Until then,
Happy bat detecting!
