Reel and spool
Dive reels and spools are reels that are used during dives.
They are used as spool for a diving parachute for example and allow the use of a parachute from a depth of 10m to 50m depending on the length of the line used.
The spool is a simple steel or plastic spool that is held with two fingers. The length of the wire is often limited.
Reels or spools can be very long and can be used for cave diving.
Finally, some stainless steel or aluminium models will be more durable than plastic models.
