I mentioned on another thread that Furunos (at least from the 1640 up) have this feature (ie motion trend vector) and how I reckoned that this was the 2nd most important feature to look for in a GPS unit (after accuracy). Nobody responded to that, so I'm probably flogging a dead horse. However, I'm trying to help my son make the best $/function decision re a GPS/sounder and was wondering if this feature is available on other brands.
Basically what it does (if you decide to turn it ON) is put a line across your screen from your boat position showing you the direction the boat is moving. This can be either with the motor on or if drifting. So if you want to set yourself up to drift over a particular mark you simply put the boat in a drifting position above the mark so that the vector line goes through the mark as you drift.
If you want (as I prefer for bottom bouncing drifts) to drop your line directly on the mark rather than dragging sinkers through it, the feature is a fantastic help in that with practice you can set the boat up so that the rear of the boat is properly positioned when you drop your line so that the boat doesn't turn in the wind and current and take your bait off the mark .
Similarly if you want to anchor up, you adjust your boat's position above the mark so that the line goes through your mark/waypoint, get to an appropriate distance and drop the anchor. Current affecting anchor rope might have some impact here.
Is anyone aware of this feature on other GPS/sounder combos? I find it such a useful feature that I wouldn't consider buying a GPS that didn't have it.
thanks
