Lakemaster Vs Navionics ? Good chip for Truman lake for Humminbird 597ci di hd?

[badaxed]

Bought both recently. One for Truman lake ( Navionics south hotmaps) the other for wisconsin (" Lakemaster "). I fish truman lake in the spring (CDC crappie camp) and wanted to have a new chip for my new Humminbird 597ci di hd locater.

I called navionics to see if the map of Truman lake was the same on the regular "hotmaps" and "premium Hot maps" that would work on this unit. I was told by navionics that they were identical in detail. They e-mailed me a couple of screen shots of the main lake. The few screenshots of the main lake looked good. When I recieved this chip I installed it in the new hb unit and was very dissapointed. The "South hotmaps" did not have any detail of any secondary bays or even a basic outline of the upper end of Tebo creek on this chip. I felt ripped off by navionics.

I also have a lowerance 522c-igps that i have a three year old chip of "fishing HOT Spots fhsp southern usa 286 premier lakes" that has very god detail of truman and all of its secondary bays and upper ends. This chip is not compatible with my new HB unit.

I also own a navionics map of wisconsin for the lowerance unit. This chip also gives only the main channels and very few secondary bay depths.

The "Lakemaster" chip I purchased recently for my new HB unit floored me with detail I have never expierienced in map chipping before. I have fished the upper Mississippi River for over 40 years, 30 years as a fishing guide and never saw a map or chip of this body of water that was as accurate in detail of almost every bay slough and channel. as "Lakemaster" chips are.
After review The Lakemaster chips in my opinon are hands down the best navigation software I can purchase for my HB unit.

My only problem is there are no Lakemaster chips for the state of Missiouri. Does anyone out there know of a product that offers "All" of Truman lake on a chip that is compatible with the Humminbird 597ci di hd.

Dear Badaxed,
LakeMaster released just last week a map card in both Humminbird and Lowrance versions that is an 'update' of their Illinois/Iowa card. It is now called the Great Plains card and covers Illinois, Iowa, Kansas, Missouri and Nebraska. Missouri includes Harry S. Truman. FYI
