I have not read the bad press about the B&G FLS ,but I am less than impressed . I had it installed a few years ago when I replaced all my electronic on board . It sends out false signals showing obstruction and then disappears . No rep could explain or solve the issue. It may be that on  the Bay we have a mud bottom ??? I should have tried to use it in the Caribbean or New England ,but forgot to and never felt I need it. Maybe next time I have a hard bottom I will try to use it and see if it works better. But right now I wish I had spent the money on a lead line.
