The older model using galvanised wire but still serviceable, rewiring with Stainless steel wire would save a few grams
No longer needed
It is an older unit but they do last well, 610 grams on my scales and personal opinion I think they work better than snow stakes as climbing anchors but only when used in pairs, these were mainly used as anchors for the big winter tents so never taken a climbing fall
Asking $50- plus postage for the pair which I think is a fair price, current retail is $48- each
I'm moving on all of my winter and climbing gear so keep your eyes open as my crampons etc will gradually get listed
