Rickie, if you buy one I'll come over and watch you play with it . I would like to see one in action or video of it on the water in use. Without knowing much about it, to me it seems like if you were using it idling around looking for stuff that the sweep rate is to slow and you'd miss a lot of stuff. Maybe later versions will have more crystals and have tha option to update the screen every 90* instead of 180*. Slow trolling it may be fine though.
