I have a Raymarine A65 cp/sonar, garmin cp/sonar and mercury smartcraft gauges. All of these measure surface water temperature. All three were different saturday when I went offshore. How do I know what is correct?
transducers inside or outside the hull? was your boat on a lift, trailer or dry-stacked before you put it in the water?
I don’t claim to be familiar with this equipment…

The Raymarine has a brand new P58 sonar/ speed/ temperature transducer surface mounted on the keel- 72.5degrees. The Garmin is mounted on the other side of the keel- 69 degrees. I’m more inclined to believe the RayMarine since the transducer is new. I can calibrate all of these - but to what? Brian
I don’t think it really matters- the difference in the temp from one area to another is where you get the most information. I would venture to say that the 69 degree was the actual water temp offshore.
