Examples? This interest me to operating a boat at night. Don't need to see my hand in front of my face but a fast transition to say 2 ft. would be the diggidy. http://tnvc.com/shop/matbock-tarsier-eclipse-nvg-focus-enhancer/ Or Drill a 5-7mm hole in a lense cap |

im not getting how just drilling a hole in a bare cap is going to refocus the lense for upclose looking? Don't ask me for sciencing - but... well, it just does. http://www.ar15.com/archive/topic.html?b=6&f=18&t=399269 It's "something something depth of field something aperture something exit pupil size something something focal distance something." That's why it works. 
You do lose a lot of light (surprise surprise) with any of these devices - so they're not "100% of the time" devices, at least not for me - but they're nice to have in the kit bag. ~Augee |

The RFR had no light loss.... Here is a Vid we did on the Tasier
