Thread: Best map card for Truman Lake

No contest. Lakemaster

LakeMaster for me by far. With the way Truman lake levels can go way up and down it is sure nice to be able to adjust the contours to get accurate depths with out guessing and trying to add or subtract for current lake level. I also like the shallow water highlight. I have mine set at 5'. Makes it easy to see where you need to steer clear of.

Do you know if you can adjust Nav? I just installed two new HDS7 gen 3 and was told to buy the nav. Hope I didn't make a mistake.

No adjustment on Navionics. LakeMaster chips are only compatible with Humminbird. Before I switched to Humminbird I had HDS units with Lake Insight. It was pretty good mapping for Truman lake and never got me in trouble when running new water.

Definitely Lakemaster, with the depth shading and being able to adjust depth contours to current lake level is a big plus, especially on Truman. One other thing I like about Lakemaster is that you can pull up any lake on the card in your driveway, kinda nice if going to a unfamiliar lake and want to get a look at before you get there, don't think you can do that with Nav.

I have a Lakemaster chip from my old boat that I'll make you a deal on. My new boat has Garmin and the chip is Humminbird only. PM me if interested.

I have had Navionics several years and plan to buy Lakemaster soon.....With Navionics I can do a "go to" to any lake the card covers and look at it from the drive way or any other place....Just letting you know......
