It will certainly work as simply another object to bounce a laser off of, but someone would have to test it to see if it works with any other rangefinder in a manner besides that. If it works with one kind of laser rangefinder it should work with them all. I don't know how the Smartstick works, exactly, and of course they want to sell their own units and don't advertise if it works with any other rangefinder. _________________ Aim Hard!
