Currently I have a hummingbird helix seven SI, but it doesn’t do what I’m looking for. I’m just not impressed by the separation of the fish from the trees and it’s very hard to see those little pixels. 90% of what I do is fishing brush piles, I am looking to upgrade. Here is what I am looking for in order:

Under $1000
Great clarity/definition
Good target separation
Ease of use
Good customer service

Presently I am looking at the German echo plus SV9. However I am reading differing views on the clarity and definition of the unit. Any suggestions would be highly appreciated as to any brand or model out there.
