When they first came out with dive computers we all said, salt water and electronics, that’s not going to work!
Two years ago I was going to buy a color display and give one of my older computers to my wife but after the DM hit her with the tank that was the end of her OW training :(
On my Cochran computer you thump the screen to turn on the lighting but I’m not sure how touch screen would work with 7mil or drysuit gloves.
