>>2330767That's got to be the most expensive and complex "solution" I've ever heard, considering how many dives and man hours it would take. Also, how the fuck is the drone gonna get down to the open shaft if it's unconnected to the wire network until it reaches the end? Do you want the divers to fucking carry it? AND hook it up when they're several hundred feet deep, and experiencing nitrogen narcosis? At 250 feet, that's like taking 5 shots--a perfect time to be fucking around with complicated and expensive equipment. But I'm the retard, sure.
