I recently picked up a handheld magnetic sweeper from here http://www.bluestreakequipment.com/ and I love it! I can't believe all the rusted roofing and barn nails, screws, staples and other crap I am finding.

This company doesn't cut any corners with its products. Great packaging (wooden crate), build quality (strong but also light feeling at the same time) and most importantly they don't skimp with the magnets (this is where all the weight is). Very strong! I am finding that it is picking up a lot stuff that is slightly buried beneath the gravel that I can't see.

I’m armed and I’m drinking. You don’t want to listen to advice from me, amigo.
