Lakemaster Minnesota v4 vs v7

Right now I have the v4 lakemaster chip for mn, the newest one looks to be v7. I normally fish p4-p6 on the river, from what I’m reading only p4 has been updated in the newest version and the rest are still the same charts, is that correct? I wish humminbird had a spot on their website to compare the different versions, there doesn’t seem to be any way to do this other than going through the lake list on each one.

Just wondering if its worth it to upgrade or not from the v4? Any other improvements over the older version for ipilot etc?

Not a one to one comparison on the same screen but the chip information is available here. You could open both PDF’s and compare.

long story short, they add more surveyed lakes every version that comes out. if you only wanted Pool 4, check out chartselect.

as far as improvements from the old version vs new for ipilot, the lakes that have been updated from the standard definition to their surveyed lakes will improve ipilot link’s features
