Not sure if you remember, or even heard. About a year ago or so, Barrick tried our product (the connectors) in a Nevada mine, and were quite impressed. It usually took 5 or 6 days to run their cable, but with Valdor's product, finished in a day and a half, and they found the transmition had better quality, less signal loss. Not sure how that is progressing.   Have a great day, and a better weekend, Sparky.
