Bought these for a different purpose than normally intended. That is to secure my Tripod/camera on slopes or windy days. Being made of Carbon Fiber, modern tripods are so light they are easily tipped or blown over with disastrous results. By screwing these pegs into the ground, then attaching to the tripod using shock cord this should make the tripod much more stable. Light enough and small enough to fit into the tripod carry-bag they could save a fortune in damaged cameras and repairs.
These are great! We had quite uneven ground where our run was placed and I used some tent pegs to secure, but the man who set the run up recommended these. I was a bit sceptical but they went in very easily and are more secure then normal tent pegs. They've been in for about 6 weeks now and haven't shifted.
