This worked well except I could not get the tides. The maps are really good and the identification of all areas are very accurate.

I use this to run the Apalachicola bay and the river. It’s pretty accurate so far from what I can tell.

Unfortunately even after spending $1100 on a helix unit you have to still spend more to get the full capabilities. But once you get this chip it is a great gps for the ocean

It is what it says it is, a bunch of maps for my fish finder. But does not tell me where the fish are. LOL

Ordered this in January to have at the coast this year only to come to find out two weeks before a week at the beach that it doesn’t work at all I have been on the phone with Humminbird without any success.
