Lakemasters chip for Idaho?

[66birdman]

Has anybody used the lakemasters chip for idaho?  I just got a sonar unit with built in GPS but I dont want to waste the money on the chip if it doesnt have CJ and Cascade on it.

Navionics has Cj and Cascade. Lakemaster is now owned by Humminbird and am not sure if they will work for other brands of GPS these days.

I'm a Lowrance guy and the insight and/or navionics has a great map for both. I have an HDS mounted on my Atv and the mapping with insight is fantastic.

I bought a Humminbird 385CI.  Will the Navionics work in it?

It will only get used for one season though.  I am moving back to North Dakota in June so unless it has the lakes I fish up there too I wont be spending all that money on a chip.
