I am talking about dropping a waypoint of something that I just scanned with my transducer, not something I marked from home. Obviously if I am marking a location from my home I am not expecting it be exact because at that point, it’s like you said, it’s general map data, not sonar data. When I create waypoints from home I am only selecting general areas, points, flats, etc. not a specific piece of structure.
What I am talking about is idling over a target, scanning it with the transducer, seeing a piece of structure in the sonar data, selecting it, dropping a waypoint so I can return to it and fish it that same day, but once I turn around and try to pass over it again and fish it, I am not finding the target. Even when trying to turn around, pass over it again and rescan it, confirm its location and get a better look at it, even though it shows I am passing over that waypoint just going the other direction, I have trouble finding that target again. I have done the things others have suggested like going at it from a different angle, trying to pass over it again and create a second waypoint to make it more accurate, etc. but I am rarely able to find that target again even when I drive to it and then beyond the waypoint I just made. I will say most of the time I am doing this it is with down imaging because I know that Side Imaging offsets are greater. Maybe next time I will find the target with down imaging but when returning to it I will pay more attention to the side imaging so that even if I am off by a few feet I should still see it in the side imaging and what side of the boat it’s on.
So my questions remains, with a Lowrance HDS Pro unit, if I select a target on the screen and create a waypoint, it creates the waypoint at the target and not the current location of the boat/head unit, correct?
