■ Lift Bag
Attach the lift bag securely to the object to be recovered, then inflate it using an alternate air source to raise the object toward the surface.
Because the lift bag is equipped with an exhaust (dump) valve, expanding air can be vented during ascent, allowing controlled buoyancy adjustment.

■ Marker Buoy
A compact surface marker buoy (SMB) that is easy to carry underwater.
Attach it to the recovery object to mark its location so it can be identified from the surface.
It can be deployed and released easily from underwater.

■ Rope
Rope is used to establish search patterns and secure the lift bag to the recovery object.
Durable nylon rope is generally recommended because it is strong, flexible, and easy to handle.
Polyethylene rope is inexpensive but tends to slip and is less suitable for precise underwater work.
A rope diameter of approximately 10 mm provides a good balance between strength and ease of handling.
