I picked up a used Ulterra MSI and now I am debating on which Helix to match with it. I am just looking for the best bang for my buck, I started looking at the Helix 7 but it appears the 9 is a bit better for resolution? The 10 I can't even understand what is $500.00 better over the 9?
I eventually plan on having two on my 16' tiller boat, one at the front and one at the back, but for now I am putting one up front where I fish the most.
Is the 9 the best for the money? Any reason to consider the 10 or 12?
Thanks!
