How not to deploy a delayed surface marker buoy (DSMB)

An Oceanblue Film.

We specialize in exploring the wonders of the Dorset Coast World Heritage Site, which is England’s first natural World Heritage Site – it is known as The Jurassic Coast.

We are so lucky to have an abundance of marine life and wrecks sites on our doorstep which are only accessible by scuba diving.

At Oceanblue Films, we are able to capture life underwater in all its glory, regardless of water visibility in digital video and still footage for your enjoyment.

This is an educational film showing the pit falls of deploying a delayed surface marker buoy using a finger reel…..
Ideally this should be practice in sheltered waters before trying it in open water.

Music track is by Queen.

You need training… and equipment that suits your diving level

ChadsGoneDiving says:

Looks like someone needs some serious practice with SMB deployment, buoyancy and trim while deploying.

That was just downright funny to watch.

Tony "Dilligaf" Gage says:

All the gear,no idea……

Awful, just awful.
Dry practice first, then in the pool, then in shallow open water, and when proficient you can use your new skills on a proper dive.

Brian Baxter says:

what about the guys up top, they would be thinking “what the hell is wrong down there” or something along those lines. like “WTF”
