Underwater Signaling Devices


Scenario 1: You’re on your dive when you spot the most amazing Manta ray gliding by in the distance, you turn to see if your buddy is paying attention and sure enough he’s looking in another direction.

Scenario 2: You are running low on tank air, and need to surface, you signal your buddy that you are out of air, but your buddy is busy observing a family of clownfish in a nearby anemone.

Underwater communication is hard enough as it is without having to constantly try to get another diver’s attention to get your message across. Signaling your Dive Buddy when he’s not paying attention is often one of the most frustrating aspects of diving, but also one of the most important things to get right when faced with an emergency situation underwater.

Over the years divers have invented several ingenious methods to signal their buddies using simple homemade sound makers, which range from metal spoons in the form of a rattler, to sophisticated electronic beeping devices. Here is a list of a few of the better underwater signaling devices commercially available in the market today.

Acou-Stick” UnderWater Noise maker
