[DRH]

I installed a Standard Horizon CP155C GPS unit with the Bizer C-Map chip for Winnipesaukee in my boat last year and found it to be a very valuable navigational aid. If you just boat in familiar water, it's value is probably not as great. But if you like to explore areas of the lake you are not familiar with, I believe a chartplotter is a very useful tool.

Using the Winnipesaukee C-Map chip, the chartplotter displays on the screen your current position superimposed on the Bizer lake chart and shows your exact location relative to markers, land, shoals, etc. True, you should also have a current lake chart with you, but I have found when boating in an area of the lake I am not familiar with that sun glare, haze, reflections off the water, etc., can sometimes make it difficult to identify what land masses you are seeing. (Are you seeing the mainland, or one or more islands? Sometimes it's not easy to be sure.) With a chartplotter GPS using the Bizer chip, you will never be in doubt.
