Makro Kruzer First Water Hunt

It was so hot again today we decided we needed a swim. A swim with the makro kruzer. Today is my first water hunt ever. Boy was it hard to put that detector down in the water. I just didn't want to do it. In the end it was fine. The only mode I could get to work in the water was beach mode. The rest of the modes were just beeping like crazy. Is that normal? Anyway we got a short hunt in, found some wildlife and didn't go home empty handed.
