Depending on the day we can probably weld them up at my shop, then bring them over. Otherwise, I have 2 MIGs and a stick welder that are 110v that I can bring out to the range. No generator, though.
I have one of those walking wheel measuring things. The wheel is small but I've measured grass with it before. Goes up to 1000ft.
I also have a very old survey transit but no tripod or pole for it. I know I can see through it but I have no idea if it still works for measuring.
