If you have recorders from the Wildlife Acoustics SM2 family, there are a number of things you should do annually to make sure each is ready for the next recording season:
A common question that people send to Jeff and me as the support staff at Wildlife Acoustics deals with how people should adjust their recorder settings. In particular, how to set gain. For example, “I’m trying to record X Species in Y Environment. How should I set the gain on my recorder?” The documentation for our equipment provides some suggested starting points, but I always tell customers they should test out their settings and make adjustments if necessary.
The growing demand for conducting passive acoustic monitoring of bats allowed me, a self-employed bat specialist, to purchase five SM4BAT FS recorders. The choice of passive recorders and analysis software today was somewhat overwhelming, but because the SM4BAT recorders are fully weatherproof, have a decent deployment time, an option to be cable lock secured to a tree and of course the three year warranty length, the decision to choose SM4BAT recorders was a swift one.
Rechargeable batteries are a great solution to power your Wildlife Acoustics recorders as they save a great deal of waste. However, if you get the wrong ones they will not work well. Most rechargeable batteries are designed for toys or other equipment where longevity is not critical. Also, many lower-end batteries will have a high self-discharge rate which means they lose power quickly, even when they are just sitting on the shelf.
