After checking the web for reviews on Lowrance and Humminbird both and finding horror stories anymore about customer service from Lowrance and wait times of months, not to mention being charged to repair units under warranty, I decided to try this out as I called them several times with questions and got excellent responses each time.
Mounted on the trolling motor on the front of the boat and I have to say it is sweet. Works exactly as advertised with no problems. SI is awesome compared to older graphs.
I have also done a software update using a sd card which worked flawlessly. So far this unit is well worth the money.

My husband and I just bought a Pontoon Boat for fishing and pleasure. We both enjoy fishing so we wanted to get some good equipment to go along with the boat and this unit was highly recommended. It may even be more than we need right now because it is "Loaded" with all kinds of good things. The graphics are easy to read and clear. The depth finder with alarm is very helpful. Even when the sun is shining on the screen, it is clear and easy to read. The sonar gives a real wide angle of what is below us and in great detail.
This unit has more maps than we will ever use, but it is good to know they are there should we decide to hit some other fishing areas.
Our boat dealer was kind enough to instll this unit on the boat for us and the hookup they used moves it in all different directions and allows us to remove it easily before trailering the boaot home and pop it on when we are ready to hit the water.
I don't see how anyone could be disappointed with this unit.
My husband, who is not a "Techie" (has problems running a computer) has learned very quickly how to operate this unit. We LOVE it.
We highly recommend it.
When I had a couple of questions, support from Humminbird was excellent too!

This device seems to do everything it says it will do, but; You need to study, study, study the displays to be able to understand what you are looking at. I am sure that I will enjoy this more after I have used it for a few months. The gps, used with a LakeMaster chart is awesome. The si, and di views need to be used at a steady speed (still to be determined in my case) but they do work as advertised. If you can afford it, the larger screen is advised. I would buy this again if I need another aone.
