minn kota temp sensor,$50. attaches to your tansducer and / or screws to your hull. tiny sensor, very accurate and updates very quickly. The head unit is on about 7 m of cable. the head unit is about the size of a matchbox, degrees C or F, a simple switch changes the setting. Air temp and time also is part of the unit. Runs off a single battery for ever. I have one.
