I have had SI up front for several years, it like other toys we have is a tool. If I am fishing boat docks, and I do a lot, it helps me pinpoint where brush may be out away from the dock. Now if I am in 25' of water on a brush pile for crappie or using a drop shot, I may not use it. It all depends on what you see as an advantage for how you fish.
For the record I tried going without it for about 6 months, had to have it back up there.
Wishin I was fishin!! ..............>(((//*>
