Digital Swimming Pool Thermometer Floating, IPX-8 Waterproof, Solar Powered

This Model SH250 solar pool thermometer is made of a smooth plastic that didn't pick up any biological scum after sitting out in my lake for 7 days. It appears to be waterproof (I dunked it a few times, and it floated in the lake for 7 days and is still working, with no evidence of moisture building up behind the plastic screen).

It includes a short nylon cord to tie it up, and the manual says it has a 300 mAh nimh rechargeable battery that is recharged by the solar panel on the top. There is a rubber covered button that will turn it on when you take it out of the box and then allows you to flip between F and C temp scales. (I can't find a way to turn it off again.....)
