After using Lakemaster cards for a few years, I wouldn't want to have to go back to the other brand. Being able to highlight a certain depth is critical for me to troll most of the areas I do on KY and Barkley Lakes.

Yes, the level off-set works great everywhere I have used mine. I usually set my shallow water red zone at 4 feet deep. It's scary to put in that water offset and see how many red areas show up 1/2 miles from shore here.
