The chances of snagging the diver's equipment on line depends on awareness of the line's position relative to the diver, and the number of possible snag points on the diver's equipment. The ability to release a line snag depends on the ability to identify and reach the snag.
In 1908 she was joined by a snag scow, Tackle (30 GRT, 64 x 28 x 3.5), which was designed to operate in much shallower waters. [4] [5] She retired in 1921 after the completion of her replacement, Bear (242 GRT), and was converted into a quarter boat. [1] Her steam engine was utilized in the snagboat Yuba (410 GRT) built in 1925. [6]
Shot, line and reel on dive boat. The shot is deployed, generally from a boat, after the dive site is located using position fixing such as GPS and an echo sounder. Shots are more difficult to use in strong currents. The weight may drag along the seabed especially if the divers pull on the line as they descend.
The diver must be able to safely reach a reliable alternative source of breathing gas at all times during the planned dive. Plans for technical contingencies may include arrangements for alternative equipment, spares, alternative boat etc. The level of contingency planning will depend on the project, and the importance of the task.

In underwater diving, a downline is a piece of substantial cordage running from a point at the surface to the underwater workplace, and kept under some tension. It can be used as a guideline for divers descending or ascending, [1] for depth control in blue-water diving, [2] and as a guide for transfer of tools and equipment between surface and diver by sliding them along the downline at the ...
The Diver Life Raft and Surf Shuttle are inflatable safety devices for diving where currents or distance could create a life-threatening situation if the diver is separated from the dive boat. They are intended as flotation aids for lost divers or those facing long surface swims. [ 70 ]
