Diving sherpa? That means you do all the carrying of cylinders, weights etc.I like the idea of seeing my wife's air without having to grab her spg. I only have to have my left arm near her tank and it should pick it up when I want that info. Same goes for when my kids start driving. Yes, they should be monitoring and reporting remaining air per our plan but that isn't always the case. Just one more layer of comfort for me since I'm their diving sherpa.
