Humminbird 602007-1 LakeMaster Premium Northeast V1

Excellent product. First use was on Lake Winnibigosish. The lake maps on the LakeMaster Premium micro-SD card provides increased resolution of lake contours that allows the angler the ability to identify structure that should hold fish. Appeared to very accurate.

[This review was collected as part of a promotion.] The mapping on the VX chips is superb. The multicolor display you can set up is excellent. Paired with being able to adjust the water levels, it will keep you out of trouble when navigating on the water.

This will sound like a sales pitch but this lake contour info is 100% putting more bass in my boat. Using this info in concert with the OBN app on my app to pre scout locations is a TOTAL GAME CHANGER! I am no longer a hopeful bank beater searching for a bite. Yes, that still happens but in controlled situations and locations of my choosing based on contour info as it relates to likely fish behavior.

[This review was collected as part of a promotion.] Would not think of navigating these waters without this chip

Perfect product. Quick arrival. Appropriate packaging.

These updates are amazing

Easy to use! Improves the basic map by adding a lot of extra details, more accurate.

[This review was collected as part of a promotion.] I bought a Humminbird Apex 16 because of the Minnkota autopilot interface. Unfortunately, that capability is only as good as the Humminbird database, which is lacking. While the Lakemaster Premium V1 boasts contours in 1 foot increments, that is not the case for the lake that I fish regularly. The database for Greers Ferry Lake in Arkansas has 3 foot interval contour lines. This would not be a problem if they were accurate. Even with the water level offset feature, there are wildly inaccurate contours and entire pinnacles that are missing. Compared to the highly accurate Garmin database with 1 foot contours, I would characterize the chart plotter portion of the Apex as a very pretty Fisher Price navigation aid. Not well suited for trolling for walleyes where precise contours allow precise bait and lure presentation.

Humminbird does not cover one of the best Large-Mouth Bass fishing lakes in Florida called HeadWaters near Stick Marsh. I purchased both the lake master and Coadtal maps because I read on Google that it covered Headwaters but ut does not. I can get a Headwaters map for cheap Lorance reveal unit but not for a high end Humminbird!!!

Don't buy this, navionics is way better. In fact the lakevu maps that are base with garmin are significantly better. I can't believe you actually advertise how great this is, it is not premium mapping as indicated. Look at the screen shots from the same lake below.
