Humminbird602010-1 LakeMaster Premium - Wisconsin V1

Pro: initially had an issue getting Helix unit to recognize the map. The problem was not the map it was me not understanding directions . After following direction I put the chip in and turned Helix on snd chip was found and worked great on my fishing trip.Con:I wished the first year it had multiple updates as other mapping companies have. I could not use one of them because of the new trolling motor I just ordered is supposed to use the map (yet to be tested).

This is a nice addition to my graphs as the maps for the water I fish is much better than previous mapping that I have purchased.

The new color pallets made the lake "pop" and it helped me zero in on so many new spots on a lake I've fished my entire life. Love it.....the google maps overlay is useless feature....and smartstrike is a bit of a gimmick.

I have purchased well over a thousand dollars of lake-master chips for the many helix units I have. The new 2d shading feature is outstanding. now with a glance, I can pick out dropoffs of flats much easier. I like the option of the three views and the ability to customize all three. I fish weed lines a lot and the ability to switch to an aerial view quickly is great. Lakemaster is an awesome mapping chip. I have these in all my helix units. Lakemaster provides superior mapping to other chips I have bought for the upper Mississippi River. highly recommend.
