Hi all,<br /> I was recently given a Hummer Piranah 1(low end) depthfinder and noticed that it has a receptacle for a temp sensor. I checked the price of a temp sensor from Hummingbird and it was almost as expensive as the unit. (50$ temp sensor, 79$ depthfinder) Does anyone have ideas on where to find a cheaper temp sensor (TG-W), OR have any suggestions on alternative suppliers?<br />Thanks for your time!
