Wanted to read some opinions on eastern nc river mapping on units. I had a 7610 Garmin in 2017 and it was ok for mapping. The Lowrance live 9 I have now in dash is fine as well. I'm thinking of trying a Hummingbird helix at the console of my next boat. Curious what others opinions/experiences are with the mapping on the bird.
Thanks in advance for whoever takes the time to post.
