Over the years I’ve encountered a few geocaches that uses lasers.  They are always fun geocaches.  I will be a guest on the GeoGearheads podcast on January 23rd to discuss lasers and geocaching.   While preparing for that broadcast I discovered this little stat.

Laser One Degree

We have done the math and over 30m (~100ft) an aiming difference of just 1 degree from a fixed location means a difference of 1.5m (~4ft) at the target.   To put that in perspective a coin under one end of our most popular laser represents 1 degree change in angle.   We learned a lot about aiming issues when we built BFL 8: Hot Blooded (Predator).  Adding lasers to your cache can be quite tricky.

We’ve found that the Laser Loci is a great way to incorporate lasers into your cache.  It removes fixed point aiming as an issue.
