When I bought my boat I had the dealer put in a depth gauge and it's a cheap POS that never worked well. I have since disconnected it. I would like to put in a unit that does water temp as well as depth and fits in the stock location. Any suggestions?

I just put in a Faria guage that does both air and water temp in addition to the depth. It is a transom mount sensor but so far seems to work well. I got it at overtons. I have had hummingbirds as well on previous boats and had no complaints so whatever looks the best to you!
