Lakemaster Chip And Truman Tailwater/upper Lake Of The Ozarks?

[tkeyte]

I bought a LakeMaster chip for my Humminbird 788 sonar. Got the LakeMaster card because it said it had Lake of the Ozarks. I put in below the dam at Truman and set it on Lake of the Ozarks and .....nothing. Does anyone know if the Lake Master chip doesn't cover the upper part of the Lake of the Ozarks or is it listed under a different option on the card? I got the Great Plains LakeMaster chip.

Thanks

It doesn't. You will have to get the navionics chip to see the channel contours for upper LOZ. Made the same mistake and had to call lake master directly to find out they don't map that part of the lake.
