yep... don't get me started... I didn't have one quite that big, but bought into the early laser stuff I think I paid $600.00 for an early laser that wasn't visible in "day light" back in the day... about the same era I think $800.00 for my 1st "day light laser" I think it took 3 of the biggest of the camera sized batteries 3/4" X 1.5" per battery...
I was so disgusted, when I saw how fast they got both better & cheaper, I swore off modern shooting electronics, almost permanently ( still have 3 of those original scope sized Pro Point dot sights on 3 of my old competition semi autos )
