So there you have it. iBobber really works I've used it to catch carp on lakes by positioning bottom baits near shelvs. I've used it to catch really big pike in Ireland I've just dangled all this thing off the edge of a boat and been able spot the underwater features, and shoals of silverfish. It's a really great tool and that uses the latest technology so it doesn't drain your battery. But the best thing about it is the price. It's under a hundred pounds. You can't go wrong.
