Always dive with a compass.

Yes and this one work great. Fits on the nose of the scooter and very easy to see when flying. Here in TO, you can get them from Mountain Co-op.

Do you have problems with deviation due to the motor, etc.? I would love to mount a compass on my scooter.

There maybe a slight deviation if you were to take a reading before you start out with the scooter, but with the compass on the nose, just point in the direction you want to go, take a bearing, and move out. To be honest, with the compass mounted on the nose of the scooter, even the SS18, the distance from compass to motor is still more then wrist to motor. So the deviation is less then if you were to hold onto the compass.

I gotcha. You are saying that so long as the compass remains attached to the scooter, the deviation is consistent. So, although you might not get an actual magnetic heading, you can still get a relative heading (straight, 90 degrees from straight, etc.). So, I guess that with one compass heading from the wrist, you can then get what the deviation is compared to the wrist and keep that in mind when following the course from the scooter compass. Is that what you are saying?

Pretty much, don't even use a wrist mounted compass now because the variance is constant.
