Well, it was worth a shot. Looks like it will be IR if I can get the shading down. If not, I may have to look into the laser. The pin point accuracy would be great for not having to worry about the shading but make it a pain for aiming. And the price of the unit is a lot more and then you have to buy a cheap laser pointer too. Thanks for testing BernardBack to drawing board: Packaged ckt. enough to be semi portable with final test good at 20 ft in brightly lit rooms; outside early evening range fell to 2 ft. Back to laser or IR?
