Saw this in the JLC mag. today. Goes for about $70.
I’m not sure how it works - i.e. how do you move it along to traverse the attic? Maybe you have to have two of them - one to stand one and one to move.
Seems like more trouble than it’s worth unless you are standing in one spot for a long period to install a fixture. I don’t see it as useful for an HI.
Most attics that I’m in the ceiling joists aren’t visible or usable, for something like that, beneath 6" or more of blown insulation.
