Testimonials:

As a long-time VFR pilot and having wrestled with the 1:60 rule and "prayer-wheel" this amazing simple alternative is without doubt the most useful tool in VFR navigation.

Ian Richards.

 

At last the guesswork has been taken out of track corrections. No pilot should attempt a cross country flight without one.

Peter Crouch.

 

The addition of a 'prayer-wheel' to the traditional Nav Aid Rule make's it one of the most versatile and useful instruments ever developed for the VFR pilot.

Paul Bedford.

 

Pilots have been flooded with 'gadgets', most of doubtful use but this navigation aid has to be the most significant aid to in-flight navigation.
