got a question about marking a brushpile with my DI/Sonar unit.....say im trolling along at 3-4 mph and I see some bruch scrolling across the screen from right to left....as its about it exit my screen i know ive already passed over it and not around the brush....but if I move my cursor over to the brush on my screen it will pause the scrolling....if I move my cursor over and pause it even though ive passed it and with my cursor over the brush on the screen i mark a way point...will that waypoint mark where the boat is at present time or will it mark it to where that brush was when i passed over it?
