I had one last summer before I sold the boat it was on. The side imaging was cool and worked great. The gps was way off when I needed it most and the depth readings on the side bar would sometimes show I was in 20 to 30 feet of water when I was actually in 1.5 to 2 feet of water. The down imaging showed the correct depth at all times. So if you can train yourself to watch the picture for depth and the gps isn’t very important to you then it will suit you fine.
Remember the gps is only as good as the map card you have. If the map was not HD then it will not be all that accurate.
This is the perfect unit if you are new to the si di gps mapping units. Very user friendly and easy to use.
There are always some problems people are having with these new gadgets. However, I have seen very little with the helix 5. Humminbird has fixed any issue that I have had.
On of the the that’s needs to be done on new units it updating the software through the humminbird website. They install fixes for any problems quickly so even if it is brand new, you still should check for an update right away.
