    Exactly what are your reservations about the utility of forward looking sonar? I really want to hear this, as it seems to be a common thread among a lot of people that are not anchoring and exploring islands that are not charted well. Please do tell.

    My reservations are simple. The shallower the water, the less range forward looking sonar can achieve. The forward looking range of sonar is usually quoted as a multiple of depth at 8-10 times depth. That means, in 8 feet of water, your best range is 80 feet and it could easily be as little as 64 feet. So, if you’re picking your way through an anchorage at 0.5 kts, you can probably put the information from FLS to good use and avoid an obstruction. But, if you’re moving even at a 2 kts, it’s going to be difficult to impossible to get the boat stopped in that kind of range.

    In essence, when you need it most, it offers the shortest range. I’ve talked to too many people who believe FLS is going to be a cruising safety tool to keep them out of trouble. I believe the reality is, it will only help you if you already know you may be in trouble.
