I am using the Impact Cosmic on my VFT and it works great. I sighted in at 20 steps(about 21 yards) and I' m hitting 2" low at 30 steps(31-32 yards), which is perfect for me. I use ' steps' cause I don' t carry a tape measure or range finder to the stand. I' ve alway used one pin, even on a multi-pin sight, so I guess I' m used to it.

My son and I enjoyed shooting last night about 9:00 PM. The pin in the Impact I think would shine in the moonlight. We were shooting and hitting the silver end of aluminum cans at unknown distances. I' m getting more confident every day with this setup
