Cressi Magnetic Shaker underwater signalling device
The Magnetic Shaker makes a sound using a ball held between internal magnets. A firm movement releases the ball to strike inside the body, providing an attention signal to nearby divers.
- Mechanical ball-and-magnet system.
- Compact handheld body.
- Lanyard included.
- Cressi part number JA702000.
Agree signals with your dive team before use. Carry the shaker where it remains accessible without interfering with other equipment.
