I'm extremely happy with this fish finder and am looking forward to all the advanced features. This is quite an upgrade for me coming from a 5" screen, non mega, non Side or down imaging Lowrance Hook. I was very interested in the ability to network this with my Ipilot Minn Kota trolling motor, which I found out I will have to upgrade to the link or advance GPS Ipilot model, but at least I'm set up on the fish finder now, less to upgrade in the future. I can't wait to tell the fishfinder where to go and let me just concentrate on the fishing. I was going to settle for the G4 MSI / MDI non networking model because of the difference in price, but then one day I logged on and saw this G4N model on sale for $244 off the normal price, making it the same price as the non networking model, the only thing is I would have to wait 6 weeks to get it for some reason. It was such a good deal I was worried they weren't going to send it to me, like it was a glitch or something but they did, and it arrived earlier than they said. I will have to wait a few months to use it on the water since its 15 below zero in Minnesota right now and all the lakes will be covered with ice until May, but I hooked it up in simulator mode so I can learn how to use it before actually getting out on the water, what a cool feature that is! I am amazed at the quality and resolution of the Mega Side and Down imaging, they are not exaggerating on the ad photos! This thing has all the features I wanted and it's intuitive and easy to use too! Those fish better look out this summer, they won't have a chance hiding from me!
