I have a Helix 7 SI combo on order and they hope to start shipping around 9/1. I found it for $639 plus $5 freight. I think it will be a big help to me since I fish in 3 private lakes and the deepest one is only 18', I mostly in 6 -12' of water. I hope it's as user friendly as they say because I will need it to be :-)))))
