This diver, wearing an ungainly suit and helmet and helped by other sailors, enters the water via a ladder.

Divers depended on external support and assistance, including a supply of air pumped through a hose. In addition to the weight of the equipment itself, additional weights counteracted the buoyancy of the air in the suit and helmet while divers were underwater, but made movement difficult above the water. After HMCS Niobe's 1911 grounding, divers investigated the extent of damage to the ship's hull. As highly trained specialists, divers inspected ships, harbour facilities, and defences.
