Tried a new hand signal for a blind lift in a tight Philly alley and the rigger just stared at me.
I learned you can't improvise when the spotter can't see you, so now I always use a radio for those spots. What's your go-to for a zero-visibility setup?

What's the backup plan if the radio fails mid-lift?

Honestly, that's why hand signals are NON-NEGOTIABLE. You need a clear set everyone knows BEFORE the lift even starts. Simple ones, like a flat hand for "stop" or a thumbs up for "good to go." I've seen crews use light signals at night too, like a flashlight. The key is having a plan that DOESN'T rely on tech at all.

Sounds a bit over the top for moving some boxes.

But what if the hand signals get missed in bad weather or low light? Seems like you'd need a third layer, something physical like a rope tug system, for when both sight and sound fail.
