Playing with my plotter (Vulcan 5) and was trying to get the boat
speed to be the calibrated boat
speed (through the water
) that was set using the B&G displays.
The boat speed shows up as the raw paddlewheel speed (100%), not the calibrated speed (68%) that I calibrated on the B&G displays. However, the adjusted keel depth
offset does work
The plotter will show, say 7.x knots, and the boat speed will show, say, 5.x knots. As much as I like the optimistic raw speed, it is grossly inaccurate. The B&G display allows correction for this. But the plotters don't see this correction (and doesn't appear to have any way to correct for it)
I did shoot a video of what i mean, https://youtu.be/4a_O5UkNcjQ
For fun, I did check my other plotter on board (Lowrance HDS8 gen1) and it shows the same inaccurate speed like the other plotter.
Any idea how to get the plotter to either read the speed compensation that was set on the displays, or set some kind of compensation on the plotter?
