Anyone checked clearance with a rangefinder?

Just curious if that works at long distance, if at all, or at night, etc. Ones with an inclinometer say they measure clearance of power lines, for instance, though I'm not sure if that would work from inside a truck. I heard about the "GiraffeG4", but that looks like it requires one to drive up to an object to measure it, which pretty much gets you stuck anyway.

 

Yeah, but mostly for things that aren't marked like awnings at gas stations, if one were delivering to convenience stores, for example.

 

Thanks, I guess people don't follow you in a line like me, and then sit there wating for me to hit them going backwards, so they can sue... not that I'm paranoid, but there's almost always someone behind me, especially at worst times.

Like I was saying about checking out parking lots, no matter where I park, someone stages their car so I practically have to hit it to get out of there.

Anyway, I might try talking a retailer into letting me play with their rangefinder to see if it's worth the trouble...

 

Not sure what you're talking about... on the truck itself or as a point of reference somewhere else? I'm just trying to get away from driving up to something that I can't get around if it's too low.
