Re: what sd card isgood for hummingbird chart plotter?
I am in VA. I have the Navionics Basic chip and it does exactly what I need it to. My unit is the H-Bird 898 hdsi. The platinum chip really runs a bit slower in these units, and the 3d feature is not available in most places, especially not many rivers. Having the chart when in the river is ESSENTIAL! It marks the channel, shallow areas, buoys, shipwrecks, powerlines, and all that good stuff. I bought mine 2 years old off of bbcboards.net, for $55.00 shipped. Well worth it. Most of the Nav chips go down the rivers and out off the coast about 3 miles.
