Aropec Tank Rattle

The Aropec Tank Rattle is a simple yet effective signaling device for recreational and technical divers alike. It’s designed to clamp securely onto your cylinder valve or first-stage, generating a clear, resonant rattle when you tap or shake the tank. Made from durable materials and fully seawater-resistant, it ensures reliable performance dive after dive.

Key Features:
Adjustable Clamp:
Stainless-steel clamp fits a wide range of valve sizes and first-stage shapes; secures tightly without tools.

Sealed Rattle Chamber:
Hard-anodized aluminum tube houses corrosion-proof beads; produces a loud, attention-grabbing click underwater.

Quick-Release Design:
Snap-on mounting allows fast attachment and removal; won’t slip even under current.

Hydrodynamic Profile:
Slim, low-profile housing minimizes drag and avoids snagging on gear or reef.

Corrosion Resistance:
All metal parts are marine-grade and treated to resist saltwater corrosion for long service life.

Multi-Purpose Use:
Use to signal diving partners, alert boat crews at the surface, or draw attention of reef fish and macro subjects.

Compact and easy to use, the Aropec Tank Rattle adds an extra layer of communication and fun to your diving toolkit.
