I have a 7. Works nicely for what I need it for. I actually have the model just before they added the chirp. The chirp will only clear up the images and improve it. I am not a walleye or pan fisherman. I primarily cast for bass pike and musky. I use it for the gps and finding contours and the down imaging to find the weed edges. When I do walleye fish the arcs are pretty clear and easy to read. The functionality is pretty easy as well. There are always really cheap sales on these units. I got mine for $450 with $100 mail in rebate and it came with Navionics chip for the US. I think this might be coming to the end of this series though. With the prices of the Elites coming down and new technology coming into the pipeline they don't want to dilute the market and only sell a few of each. Better to sell a ton of a few to lower production costs and stay competitive in the market place. I could be wrong though.
Is this an in store sale only? I went online and it was still $500. I need a new unit for the bow of my boat. I was contemplating the Elite 5 for the bow but if the hook is that cheap I might go that route.
