The transducer and control box sells for 1500. You can find it cheaper if you're patient and shop around. Then you have to have a compatible Garmin unit. It can be used in any situation, but it also can aggravate the fire out of you. There are more fish than you can imagine near your boat all the time. Doesn't mean they'll bite though. A lot of them spook, or just check your jig out and swim off.
Shoot me a message when the shellcracker start turning on, plan on coming down your way a few days and pestering them.
