This is probly been covered a million times but I missed it and im new to the high tech electronics. Im wondering how to use the water level offset function. My home lake grenada fluctuates alot and im hoping this will help me out. How exactly do I figure the offset? Say for instance rite now our full pool is listed at 215.00 and water level is 202.40 so its 12.6 foot below full pool. Would I just set the offset to -12 and roll on?
Nope, it would be closer tho. Take a reading and adjust accordingly, make you map match your depth finder reading. Most of the time that is not the same as the pool readings and what you would think.
I think I can handle that! Thank you Mr. John!
No problem man, good luck
Yep, like Rees said. Get on a contour line on your chart, read the actual depth and adjust accordingly. You're good to go!
GOOD LUCK, Drew!

Sorry, I meant Erin! My bad!

Going further with what Reese said, the reason you can't just adjust from summer pool level to current level is you have to know the lake level when the map was charted. (for a corp lake the level could flucuate a lot during the period of charting) If you knew the actual charting depth then you could adjust a lot closer but you would probably still have to set it with actual depths as Reese said.
Erin, let's clarify something. Are you talking about the offset in the Lakemaster chart or the offset in your unit? 2 different things. If for chart what the other guys said is the way to do it. But your unit has a offset feature in it also. It can be used to offset death for transducer in the water.
I can't ever find that one!!!:banghead:banghead:bangheadQuote:

Depth Offset (for adjusting xducer immersion depth in the water) is under the Setup tab ...
Depth Offset should always be adjusted before adjusting Water Level Offset ...because Depth Offset is "offsetting" the actual digital depth readout to account for the water above the xducer ...
And then the digital depth readout is used as the "target" for adjusting the Water Level Offset (for the LakeMaster spot sounding to match the digital depth readout) ...
Depth Offset need only be adjusted 1 time (or after Restore Defaults) ...
Water Level Offset should be adjusted every time water level in the Lake fluctuates ...

Thanks, Rickie for clearing that up for us.

Depth offset. Nice. Now I don’t have to constantly do math in my head while fishing
Rickie, if your xducer 2 ft below the surface, then your depth offset should be set at +2 , correct?

Correct ... Depth Offset is "offsetting" the digital depth readout value ...Quote:
