Underwater Noisemaker

You've just seen a great white. You're out of air. Or perhaps you discovered a gold brick in the sand. How do you get your buddy's attention, or help from others?

The solution

Give ReefNet's new "H2YO" a shake to emit a loud and distinctive rattle that can be heard at great distances underwater.

The benefits

There are many reasons to use an H2YO instead of alternative signalling devices:

• It can't be forgotten on shore/boat like a tank banger since it stays on your BC
• Both sound patterns are unique and easily identifiable. Neither sounds like a tank banger...the days of wondering "who's banging?!" are over
• It doesn't require an air supply like many other noisemakers
• It doubles as a gear identifier (different colours for different people)
• It's virtually indestructible
