I just ordered a new helix7 si g2 also, i have a helix7 sonar right now on the console but want the si for the bow, i have a minn kota v2 with i pilot (not link) hooked up to the helix sonar but have never used an si unit before....so scott definitely give a review! ?
Now since my sonar unit is the original helix, whats the big difference between the original and the g2 si? Thanks
