Warning: I thought the new wireless elevator test tools were just a gimmick until I used them on a job in Phoenix.
I was working on a high rise there and the old wired tester was a pain with all the long shaft runs. A guy on site had a set of those Bluetooth enabled tools and let me try them. I could check door lock circuits from the pit without running a line all the way to the machine room, which saved a ton of time. So, what's your take, are these wireless tools actually worth the money or just another thing to break?
Grabbed a set for a hospital job in Tucson last month and @paul_owens25 is spot on about the time savings. I was checking lock circuits on a 12 floor bank and being able to stand in the pit with my phone was a game changer. No more running lines through the shaft or yelling at someone on the radio. The battery life is decent too, I got through a whole day on one charge. Only downside is when you drop a tool and the Bluetooth disconnects, but it reconnects fast. Definitely worth it for me, just don't leave them in the truck overnight in the cold.
