Navionics ~ driving me insane!!

I recently purchased Hotmaps 07 for my h20. Almost every lake on my chip is messed up, depths are off and the shape is way off! On the h20 it looks nothing like the lake???? whats the deal?

I have hotmaps built into my humminbird and have noticed a lot of map offset on some lake. Where everything is correct but my map seems to overall be further south on the screen than where I actually am. Also the maps are only as accurate as the depth info they had available when they created them.

Just what I have noticed anyway.

Depths are only accurate to level of lake when mapped on ANY chip.

What you are looking for is how accurate is it to breaklines or breaks on structure.

That being said the HD maps are the ones on any chip that are close to decent. The rest of the maps just give you a general idea. Which is still better than nothing on any of the chips.

I got the Hotmaps 07 for mine and it seems pretty accurate. Ive only got my H2o to be accurate to 22ft. so obviously it will be a little off.

They are the only ones that map any lakes for Colorado. They are awful, I wouldn't be surprised if Crayola owned the copyrights on them. My Expedition GPS can't even find them on searches either.

I've got the same set up. For the lakes i fished so far it has been dead on. My EPE usually floats between 12.9 and 16.8 feet. I see the depths are a little off but it still puts me at the top or bottom of breaks or ends of points dead on. The water levels have dropped i'm sure since some of these lakes were mapped. Just my .02 cents

I have the lakemaster 07' chip im my H20c and it is crazy accurate..

If I'm on the Whitefish chain and stop on the 20ft contour it's 20fow or really close.

Mille Lacs is right on.

Clearwater is the only lake so far a little off but that lake has very steep sharp structure.

I have the Nav chip for michigan and the northern premium chip and still perfer the 07' Lakemaster. even the 08' Lm chip did not impress me like the 07'

even looking for small humps and holes the thing is deadly accurate on 99%of the lakes if fish.
