Had to send it back because if was off by 10 degrees. It said the water temp was 32 degrees on a late May middle of the day trip on a tail water that is almost always 42-48 degrees. I checked it against my refrigerator thermometer and found it was not off by a constant amount, but it varied between 7 to 11 degrees. Decided it was not for me and sent it back for a refund, which Cabelas not only refunded my purchase price but also the shipping amount. I love Cabelas!
Decent workable tool, but the scale is small and hard to read with my older eyes. Also, the temperature on mine consistently measures about 3 degrees below actual temp, so i need to add 3 degrees each time i read it.
