Join the Halcyon App Contest and Win a Symbios Dive Computer

We’re excited to invite you to be part of something new and fun—the Halcyon App Contest! It's our way of celebrating the dive community and all the incredible moments captured beneath the surface. The first edition of the contest is officially live and will run through July 31, 2025. If you’ve captured a special moment underwater, now’s your chance to share it with the Halcyon community—and maybe even win a Symbios Handset Dive Computer.

 

 What’s the Contest About?

Every two months, we’ll launch a new contest theme inside the Halcyon App. Our first theme is simple but powerful:
Best Underwater Photo

Whether it’s a reef bursting with life, an eerie wreck, or a calm cave dive, we want to see what makes your dives unforgettable.

 

What Can You Win?

The prize for this round is one of our most exciting innovations: the Symbios Handset Dive Computer. It’s built to support everything from recreational dives to advanced technical exploration, with an intuitive interface and full app integration.

2. Use the hashtag #MyHalcyon in your caption
3. Share your post with your friends and fellow divers—the Halcyon team will review the top 5 most liked posts

Why We Created This

We launched the Halcyon App earlier this year as a way to bring divers together—whether it’s sharing gear setups, logging dives, or simply connecting with others who share a passion for being underwater. This contest is another way to celebrate the stories, images, and spirit of our community.

And don’t worry, if underwater photography isn’t your thing, new themes and contests will be launching every two months with more chances to win.

Who Can Join?

The contest is open to all Halcyon App users aged 18 and over.
