[Senter Cove Guy]

Normally, a second diver would be preferred during ice diving, however, for a fairly simple recovery, it's not really necessary. You'll notice in the picture that the diver has a yellow rope attached to him while diving. A rope tender on the surface holds the other end of the rope. The diver and the rope tender communicate with each other via rope pulls. The diver has a main breathing tank and regulator and a backup tank with a second regulator. If the diver needs help getting back to the surface, he gives the rope a series of tugs and the rope tender pulls him back up.

Ice diving always requires appropriate thermal protection which is usually a dry suit, thermal underwear, hood and gloves.
