When I installed my sounder I opted for the thru hull transducer which meant I lost the temp feature on the sounder At the time I wasnt too worried about it but it is definately a feature I missed.
Looked at a brochure the tother day and It had a Min Kota stand alone temp unit..cost $44
Gave it a test run yesterday and its all [smiley=thumbsup.gif]
Gonna be chasin a few pointy fish this year so I figure it may be handy
For those that chase the pointy things how does temp changes affect your trolling patterns
