We have Perfect Pass on our Mobius LSV and by hitting Menu and the up key at the same time it displays the lake water temperature. This has been very valuable in determining wet suit usage or not and from the factory the temperature reading seemed right on. However, last weekend we took the boat out after not using it for about 4 weeks due to foul weather and the temp reading is about 10-15 degrees too high. During the four weeks the boat was in outdoor storage on the trailer with the boat cover on - that's how we store it every week. I know the temp reading is off because the lake is usually in the 55-65 degree range and the display was showing 70-78 degrees. Any ideas on why the reading would be off? I realize that you can recalibrate the temp, but that means figuring out what the temp really should be and setting the temp display to match. I don't understand what would have caused the temp sensor to misread. Anyone else see this?
