Humminbird 411610-1 Helix 7 Chirp MDI GPS G4 Fish Finder

So far it is performing nicely. Many features on it that I won't use but if you only want basic depth and where the fish are it is fairly easy to figure out. Operators manual does not come with it but is accessible on line.

Excellent display and features. Highly recommended.

Easy to install and use. For it's price point there's a lot of features

I wish I would have know there is the exact same model available but with an "N" at the end of the name. The "N" stands for "Networking." That model is required to connect the Helix to a Minn Kota trolling motor for the follow-the-contour feature. (Also requires additional purchase of LakeMaster map card). Well now I'm out $600 and there is no way to add that feature to what I bought. I would have to throw this away and shell out $750 to get the "N" model (plus a LakeMaster card for an additional $150). I might spend $800 for follow-the-contour but I'm not going to spend $1,400 for it. I hate that you have to spend 50 hours online reading about their entire product line in order to figure out what you really need to buy.Even after 50 hours of research, I still haven't found what cone angle I have. So when I'm in 20 feet of water, how much bottom am I seeing on screen? Is it showing 2 feet of bottom or 8 feet of bottom?Additionally, the MEGA Down Imaging view is fine at showing structure on bottom but it stinks at showing fish. I need the 2D sonar view to see fish. But I need the chart to steer since I don't have follow-the-contour but there just isn't enough screen real estate to display all that.Additionally, SmartStrike is not available for the lake I fish so there is another feature I can't have.Otherwise it's a fine unit.

Second one I own for my boat. Installed on the trolling motor at the bow. Works amazing and has clarity, ease of use and detailed under water information during scanning. Definitely worth the purchase
