I wish that Garmin has just paid Navico for the rights to start with and then made the best product they could. Raymarine did that and quite a few people claim that Dragonfly does better down imaging than Lowrance. We, the customers, would have been better served, this mess would have been avoided and the Garmin brand wouldn't have been damaged. Water over the dam.
Bail on Garmin. Haha!!. I make my decisions based on what I want in performance, not whose name is on it. Absolutely no way I would give up 7610, Panoptix, Garmin 2d or my GT8, GT50 and GT51 transducers. Also not giving up my HDS running 83 kHz or my Vexilar Edge3. There are specific circumstances where each helps me find or catch more fish.
I can't say enough good things about the Vexilar company. Perfect score on customer support in my book. Lowrance burned a ton of other people in the past and me specifically. I still have and use Lowrance. I regret they treated customers in the past the way they did, but the 83 kHz is still a stellar performer, sometimes unbelievable. I did get mad at them but I'm not going to spend extra money on something else just because the box says Lowrance on it. There are Garmin customers who justly feel short-changed over the DownVu/ClearVu fiasco. I'm not one of them. I have the GT xd's.
About all that I can say is that each unit I have, regardless of brand, performs the specific functions that I bought them for. I did return a Raymarine product after it did not perform as expected and as customer support said it would before the purchase. But I bought it from Cabelas so there was no hassle returning it. That when I began researching Garmin and ended up with the 7610. I am very pleased with my current setup.
There are two things I want that I don't have. First, a cheap 5-6 degree high wattage transducer. I'm to cheap to shell out the money for one of the big Airmar's that would do this. Second, I wish the technology would improve to the point that a fish on the bottom would be differentiated from a rock on the bottom next to it. Once upon a time I bought a Genetron GT9 because quite a few claimed it would do this. It did not.
