What type of thermometer do you think is the most accurate for calibrating your depth finder.? I tried my digital meat thermometer side by side with the transducer and was 8° off. Then I took the ducer out of the water and calibtated it to the NWS air temp. It was 3° off. I now want to check how the air temp calibration compares to the water temp calibration just to see how close together they are. I know ... sounds silly but my inquiring mind wants to know.
