When we posted a guide to the scuba hand signals every diver should know , many of our Facebook fans responded with their favorite signals.

Big Shark Behind You!

Sometimes, you really need some emphasis!

Bull@!#$

Keep this in the reserve in case you don't see that really big shark.

Hooray!

Epic animal encounter, successful dive, passed skill test ... there's plenty to celebrate on scuba.

I Have to Pee

They say there are two types of divers out there: Those who pee in their wetsuits and those who lie about it.

I Love You

Aw, buddy love!

LOL

Don't lose your reg!

You Broke My Heart

Maybe underwater isn't the best place to profess your love.

You Pay for Drinks

When you're killing time during a safety stop, happy hour often comes to mind.
