I bought this used and used it exclusively for stream crossings. After each stream crossing, I rinsed it with water, dried it completely, and applied silicone spray, but rust has appeared on the horizontal axis, etc. The trigger movement is smooth. Use at your own risk. I will not be held responsible for any accidents or injuries resulting from the use of this cam. No individual sales. No price reductions. Even during comment exchanges, the first person to purchase will be prioritized. I do not create exclusive listings. Once purchased, returns and refunds will not be accepted, so please carefully check the size, condition, etc., before purchasing. I sometimes go on expeditions for climbing, and in those cases, shipping will occur after my return, so the shipping time is set to 4-7 days. However, I can usually ship within 1-2 days.
