It looks like Titley Scientific are about to release a new version of the Anabat built specifically for long term monitoring in caves, tunnels and roosts.
The features all seem sensible enough:
- Long running times on internal batteries
- Temperature logging
- Waterproof case
- Sealed mic
The rugged peli case style housing looks up to the job and the (let’s hope) waterproof mic will be a great step forward for Anabat. But it raises the question; will the sealed mic be available to retrofit existing detectors?
A long time bugbear of the Anabat when used underground is the, what seems to be, inevitable burn out of the mic once condensation builds. My record is 5 mics in a season monitoring Myotis swarming sites, not just an expense but also frustrating because of lost data and downtime.
As an existing user I don’t want to replace the Anabats I already own, I want a mic that allows me to use them without that headache. It’s one reason I’ve been contemplating switching to the SM2Bat+ from Wildlife Acoustics.
Let’s hope there’s some good news for existing users too.
With a price of £307.20 the Anabat Roost Logger could be a game changer although that depends if it’s capable of species identification or just Monitoring activity levels and temporal patterns at any roost.
Whilst the Titley webpage states it’s compatible with existing software it’s a bit vague on what information is captured. Activity and species ID for under £500? Maybe that’s a bit ‘moon on a stick’ at the moment.
If it is just an activity logger it’s still a useful bit of kit of course, especially for initial swarming site research, but you’ll need to place more expensive kit in the field to identify what bat species are using your site.
*** Update as of 4.9.2012 Reply from Titley states that the datalogger “still presents data in sequence file and ZCA formats, the same as all previous Anabat units. The major difference is the ability to deploy it for long periods and program it to record selectively as the season changes”.
