Blind Spots All-In-One Pilots Ruler

The Blind Spot's Original Pilot's Ruler has been designed to offer pilots maximum support, in the simplest way. The concept enables the pilot to solve VFR navigation problems and provide useful information, both at a glance, in only a few seconds and with only one instrument!
The use of the ruler is extremely simple & fast.

The pilot can concentrate more on flying, less on calculating, thus fly more relaxed and safer.
