Hello everybody.
Actually I’m fishing on a 25Km2 lake.
I have mapped most part of if but not yet some, like the center of the lake.
Since all the central part of it is 250m deep, is there a way to insert in reefmaster a manual depth /spot / track where I don’t have the sonarlog but I know how deep is?

Thank you

One option is to use the "spot depths" function and add depth points manually - this might work if you don't need too many.
