Ulterra gmail looking for fish finder.

I purchased an ulterra and mounted it. Works great. It's a 80 lb MDI IP. I'm looking for a fish finder to see fish. My console locator will do the rest. I'm fishing wing dams and want to see if fish are present. My console locator foes not show fish very well. I think it's a hb 858c. What's a good locator to see fish that I can use the ulterra with? Thanks for any help.

The Helix or Solix units will show fish much better than the older Humminbird units like what you have.

Hopefully you got one and love it!

I don't know how gmail got on my post. Things acting very weird.
