Dual-Size Aluminum Emergency Whistle Set (10pcs)

About this product

Key Features

Dual-chamber build, one carrying blast. Two resonance chambers stack the airflow into a sharper, more penetrating tone than a single-chamber whistle — loud enough to cut across a campsite or a noisy field, not just a room.

Anodized aluminum that marks clean. Engraving ablates the anodized layer to reveal bright metal underneath, so names, numbers, and logos land in high contrast.

Lanyard and keyring included. Every whistle comes ready to wear or clip on, so a finished piece goes straight from the engraver to the gift bag with nothing else to source.

10 per pack, enough for a full run. Sample a few finishes before committing to a bulk order, or personalize a whole team in one sitting.

Perfect for team-building gifts, camping and hiking kits, pet collars, referee and event-staff gear, and small-batch merch.

Good to Know

Clamp each piece before engraving. The rounded body rolls easily — a jig or fixture keeps it from shifting mid-job, which is the most common cause of a crooked mark.

Test settings on one whistle first. Too much power burns through the anodized layer and leaves a dull, ragged mark instead of a bright silver one.

Store dry and padded. Moisture and knocks chip the anodized finish; keep spares in a pouch rather than loose in a toolbox.

Keep away from young children, and don't blow a whistle close to anyone's ear — including your own when testing.
