Well, comparing the 1000 dollar 93sv to a humminbird mega unit probably isn't fair. Just gonna put that out there. I paid $530 for my used 93SV from a guy off of BBC, and for that 530 I LOVE it. Side imaging could be better. But I actually love the charts. I upgraded to the Lakevu ultra and think they're good. The graph, for the price, is great. I can't speak on the high end garmin units. I have heard from other users than panoptix is the bomb. But again comparing 93sv to mega unit just isn't fair.... two totally different price points.

Garmin makes a great product and have always been a staple in the Saltwater world, but the thing that limits them somewhat is the thing they limit you to only their mapping, which I hear is good on lakes they have mapped. With Humminbird and Lowrance, both have multiple mapping options(Lowrance-Navionics & Insight)(Humminbird-Navionics & Lakemaster) so that there is a really good chance that there is mapping available in your area. If not using the Panoptix, not really seeing a big advantage to switching over. Like stated above, if using the higher end units where Mega imaging is an option, that is definitely a good route to go. JMO

I switched from them.... mapping was the desision maker for me , not having access to navionics was a deal killer.

I bought one for the bow to do Panoptix. Haven't had it on the water yet, but my early impressions of playing with it a couple of hours in the garage are not having touchscreen like on my HDS units is a hard adjustment, the operating system of the unit seems very "unelegant" compared to Lowrance. Their Homeport software is pretty cruddy compared to Lowrance Insight Planner as far as viewing maps at home on your PC and managing waypoints.

The positives are Panoptix and the ability to build your own contoured map which I will use heavily at two small public lakes I fish that Navionics etc. does not support that have a lot of humps and other structure. I also like the color shading ability to custom set depths on their map, e.g. 1-5 is light blue, 5.1ft to 10ft is a darker blue etc. - would love Lowrance to knock that off. Kind of a get what you pay for deal?

I bought the 73SV and guess I didn't do enough research. Even though it touted "17,000"lake maps, I got used to flipping between Lowrance maps and Navionics.
My Garmin won't take Navionics....
Other than that, for a $400 unit, it's easier to see than my old HDS-5 Lowrance....
