Customer Reviews for Humminbird - CoastMaster U.S. Coastal V1 Map SD Card for Fish Finders

I bought this awhile back. It’s not too bad. I was hoping for more definition on underwater targets. The navigation is close, but not exactly on. Readability is good. Contours and coverage ok.
I would recommend this to a friend!

[This review was collected as part of a promotion.] I have a Helix 10 and this map works well for me. I questioned whether it was going to work at first because the owners manual did not mention Helix, just the newer models. The only thing I see doesn't work is the dry land images which I dont need. I love how the map/Helix combo works so well with the Minn Kota I-pilot motor. Less time fighting a motor and more time fishing.

This mapping chip brings out instant clarity to the bottom structures and depth changes collar anglers want to see . I use the same chip no matter where I am in the east coast and Florida gulf as well .

I made the switch from a popular charting chip and So far I’m very pleased. Very easy to navigate, accurate and most of all I don’t have to purchase anything else in the future.
