Cressi Shaker Magnétique

A magnetic shaker is how you get your buddy's attention without banging a knife on your tank. One shake carries further than a shout and does no damage to your gear.

What a magnetic shaker does

Underwater, sound travels well but voices do not. Getting a buddy to turn around is one of the genuinely awkward parts of diving, especially when they are ahead of you and looking the other way.

A magnetic shaker solves it with a sharp rattling sound that is easy to make one-handed and easy to recognise. You shake it, they turn.

It needs no batteries, no air supply and no setup. There is nothing to switch on and nothing to go flat on the third dive of the day.

Why not just bang your tank

Tapping a tank with a knife or a torch is the usual improvised alternative, and it works, but it chips tank coating, marks your knife and sounds alarmingly like an emergency signal to every other diver on the site.

A shaker makes a distinct, lower-urgency noise that reads as "look at this" rather than "something is wrong". That distinction matters on a busy site.

It also keeps your hands away from a blade while you are trying to point at something.

How divers use it

Clip it to a BCD D-ring with a lanyard or retractor so it is there when you need it and not dangling where it can snag.

It is most useful for photographers signalling a model or a buddy, instructors managing a group, and anyone diving with someone whose air consumption differs from theirs.

Rinse it in fresh water after every dive, like everything else that goes in the sea here.

Buying from us

We are an official Cressi dealer in Qatar and we deliver across Qatar.

It pairs naturally with a spiral lanyard or retractor so it rides close to your body, and sits alongside the rest of the signalling kit like buoys and torches.
