I did my update over the weekend, file took the first try and it was easy as pie to do.
I had a unit loaded with 3.01 from factory and I had very few problems with the original so I was hesitant to update. I fished a few places over the weekend, from 18 feet to 38 feet and it worked fine in dynamic and auto depth. I fished close to a buddy with a Ice 55 and didn't need to tune him out at all. I was using jigging spoons and buckshots and had the sensitivity between 5 and 8, I would fine tune with the target adjust to keep the marks the size I like them.
Overall I was very impressed, I was able to chart the bottom hungers easily and see them come up off bottom. With the showdown you cant distinguish between a bottom huger and your jig so you loose alot of info.
I'm curious to know what people set their ping rate at, I thought this is for open water mode more so so I keep it at 2 but I never really played around with it much.
