Course Mapping

Had a good play about with my system yesterday with on skiers present.

 

Mapped the course a couple of times & was interesting to notice how the timer beeped

several metres before the boat got to each buoys.

 

I mapped it at about the ski pole & I'd guess the system triggered about 2 metres or more before the pole passed the buoys.

 

I Know GPS position is never much better than +/- 3 or 4 metres.

 

What do other people find?

I don't know what system you are using, Zero off or Perfect pass, but in Zero Off, you should map a slalom course when the gates are even with the READ HEADS and NOT the pylon. In the jump course, you map with the gates even with the pylon.

I mapped mine the other day(SG Z-box) at the engine box per instructions received from PP and when I went through the course at speed it beeped right as the bow hit the boat guides at the gates and each turn ball. Did the same thing on 2 courses in both directions. I guess it doesn't matter if it's consistent, just thought it was strange.

My boat has an outboard... so do I map it when the outboard the in between the gate buoys, or when the middle of the boat is at the buoys?

 

It probably wouldn't make much of a difference either way, but I did find at strange that the instructions referenced the engine box for the mapping and not the ski pole.
