This is pretty cool technology. I've never seen a good demonstration of how it works. That's my hand on the left side showing where one camera is at the bottom of the mirror.
That little beaded chain on the handle is an amazingly efficient piece of this tool and is adaptable to others. It never gets in the way since it just moves aside. Even upside down it allows one handed operation and is easily rolled off the end of the handle with the hand. It's even adjustable for length. Just snip it to length and clip the ends together. (Note: Real GI Dog tag chain and fastners are stainless. I pulled a hunk of what looked like rock out of the ocean and found pieces of this chain sticking out. When the rock was chipped away the remains of car keys. Brass, steel, attacked by the salt. Dog tag chain looked like it had just been issued.) Safety tip: keep all of your skin clear of the area between the handles. When the rivet pops it BITES!
Windshield seal leak detector. Foaming window cleaner on the outside and air hose directed at the seal from inside. Factory urethane seal rarely has voids. Most aftermarket installers don't do so well and I end up drying lots of wet carpet.
Reminded me of several bar bets I would've won at the range on Sunday. Started with several light primer strike "bad" rounds that I bet would go bang if they tried it one more time. But the best was the young guy with the Ruger 10/22 that told me the bolt wouldn't lock back. I bet him it would and did it so fast he didn't even see what I'd done. When it was time to resume firing he couldn't get it unlocked. His buddies were laughing when I tried it and "click" ... it was unlocked. They were howling with laughter when I stepped down from the tower and flipped up his folding rear sight after he'd started shooting. Turned out he was an armorer.
Nope, it's not the great pumpkin. It's a fender cover protecting me from the dirty hub that I have to work around. Same thing works when you have to rebuild a toilet. Big trash bag over it keeps you clean while you access the parts you need to repair. This becomes especially important when you could get your hair or beard caught in something nasty.
