Question
pikerliker
I have a Lowrance ifinder H2O and have an issue. I purchased it new in 08 and bought a used navionics map chip from a co-worker (mid west states). I have noticed almost since I bought it that what reads out for depth on my H2O does not match the depth reading that I am getting on my sonar. I recently have noticed that my position is off quite a ways. I was recently driving on the ice about 100 ft or so parallel to the shoreline on a local lake. My H2O showed my position as about 100 ft or more on the land side. So in short it was a minimum of 200 ft off from my actual position. These units are supposed to be accurate within a couple of feet. My question is do you think it's the map chip or the H2O itself?
Thanks ~piker
