Humminbird411610-1 Helix 7 Chirp MDI GPS G4 Fish Finder

Still learning the operation but very pleased with the purchase. Navigation in the dark will never be the same. Haven’t used the sonar yet. Will review more once I have.

Images are so clear on this, you'll see things.

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.

We live the Hummingbird! Super easy to understand, set up and use, vibrant colors!

These are the perfect weights for decoys

I use it to search for new dive sites. And it helps me gratly!

Just what i was looking for to find stucture.great.

I purchased this several months ago. I installed everything according to the installation instructions. This required removing the decks to install the transducer. It wouldn't show any data. I spent countless hours researching before I contacted customer support. I had to go through countless hours of help videos and tech "help". I had to submit installation photos then pictures of the screens with no data (which I had to be on the water for).I was sent a new transducer. I removed the decks again and installed it according to the instructions. Again no data. Went through the customer support tutorials AGAIN! I was told to update the software. I had to purchase an SD card, download the update and take the boat out again. Still no data.Now I'm told to mail the unit back for service and repair. I've never even used it. I purchased a new unit, not a rebuilt one.Their customer support drug this out so long I'm outside of the Amazon return window.Save yourself the headache and choose another brand.
