Omega Pacific Link Cam, full set of 4. I purchased these several years ago but am selling them because I haven't used them much. They are heavier than other companies' cams, but they are excellent, covering the range of 2-3 cams from other companies with a single unit. I used them in alpine environments, so they haven't experienced the impact load of a serious fall, but they do have a reasonable amount of wear from rubbing against rock. These are used items, so use is at your own risk. No claims or returns accepted. I will cover the shipping costs, so please refrain from price negotiations. I will not sell them individually.
