That's a big O ring on the battery case door...I haven't heard of one failing yet. I love how quick and easy it is to change batteries on the AT.The battery case seems like it is not a tight fit. Or maybe I am used to tightening things like Mr. Good wrench. I don't see how it can be waterproof. At least not like how I saw the blond lady in the Garrett video throwing the at pro in the water like that.
