I've been looking to buy a good fishfinder for my boat. I will be using it mostly on Flathead. I would really like one with a 7" screen, but I have no idea what other options are really worthwhile. I'm sure there are a million opinions, but I'm open to any.
If it was me I'd go with the hummingbird helix 10 or any hummingbird onyx series. They have the active map feature which lets you build your own maps of the lake on the fly really sweet feature.
I would avoid the Onix units. They are slow to boot and need to be constantly updated. Not to mention Humminbird is no longer manufacturing the Onix series. The Helix Series are good reliable units and some what affordable.
Bummer they looked like a very sweet unit. All the searching I've done has for sure put me on 2 the helix 10 best bang for your buck for sure.
What's the 2nd unit?
