yea, I’ve tried every combination of IR, cone angle, other settings, just can’t get it to where it was last winter. I had the thing dialed in last winter and it was perfect, I almost sold my vexilar i was so impressed with the Helix. Last winter I think the highest gain setting i ever went up to was 10, and that was high, most of the time it was 7-8.
The bottom jitter is hard to explain, I set the bottom to read say 19 ft and I see bottom at 17 ft. I know it’s 17 ft because I’ve been fishing the spot for years. it’ll read the bottom at 17, but then the chart will flicker, read 17.1 or 17.2 or 17.3 for a fraction of a second and then go back down to 17.0. I know it’s not reading something on the bottom because the chart has steep square edges and not a nice rounded curve that you would see if a fish was cruising on the bottom or something.
I might try to revert back to an older software version, but, i don’t want to screw my unit up. If anyone hears anything, post it here!
