In order to set it you need to know the water level at the time of survey. For Grenada, I use summer pool when looking at home but no idea if that's accurate.

Does anybody have the lake level of the big four and water level offset preset at home to look at lakemaster before you fish. Like what I'm trying to ask is... if bulta or Sardis is at 212 for instance What would be the water offset to lakemaster without being on the water. I usually set it when I get to the lake but if you want to study maps at home it would be nice to preset water offset compared to lake level and look at fishing spots on the big 4. Believe this would be a great sticky also. Sorry so wordy but hopefully the question is understood. Just would like to look up water level of a lake and then know what to set offset to plus or minus

I always have to reset on the water.
You have to get on the water, get on a contour line with the depth and then enter the difference (+ or _) to whatever your fishfinder depth is as your offset to be accurate.
