Terrific cheap insurance against hitting anything buried
I had to dig a 100' trench in my yard to bury a 1" plastic water line and also conduit with power. I know from past experience that it is a virtual certainty that sometime in the future, I am going to need to revisit this area and I will wish I knew EXACTLY where those lines are located. This tape is just the ticket. Using any metal detector, I can quickly and painlessly find the buried lines and avoid a disaster. I cut one sprinkler line digging this trench, if this marker tape had been covering it, I could have avoided that repair. I simply dug my trench (about a foot deep), laid my lines and then refilled about 8" of dirt and then laid this aluminum foil tape on top and filled the final 3-4". I tried to keep the tape in the top "shovel depth" of the trench, so I would see it on my first shovelful if I ever dig it up. A cheap and great way to permanently mark anything underground where there is a chance you will cross it in the future. It should last forever, or until I excavate it out.

Seems to be good quality
Seems to be nice, hopefully this will keep any future homeowners from hitting the mains I worked so hard to put in.

Good product
Well made, perfect and easy to use for marking the trench we dug to add a solar system from a new barn to the meter. Gave it a 4 because we had to buy so much. Only needed 175' and may never use the rest. Maybe an eBay resell?
