New Retra Flash starts shipping

A revolutionary underwater lighting system.

The new Retra Flash is packed with innovative features never before seen in underwater flash devices. Take a closer look to see why it’s already being called a game-changer.

World’s first underwater flashgun with a fully circular flash tube. We made no compromise when it came to power and quality of light. The new Retra Flash produces a smooth and powerful light output like no other flashgun this size can offer.

Made for the 21st Century. Retra Flash is the first underwater flashgun with Smartphone Connectivity via Bluetooth (patent-pending technology). Set advanced features like HSS, Smart SL or update the firmware via the free Retra UWT App.

We are dedicated to building systems. The new Retra Flash is an underwater lighting system made for the future.

An unparalleled testing regime. A combined total of more than 1,4 Million test shots were made with prototype and pre-production units of the new Retra Flash. We’ve tested the material to destruction and made improvements anywhere possible. The final result is a robust flashgun that delivers anything you ask from it.

Standard features no other flashgun can offer: Leakage detector (patent pending technology), Multi-level AA battery indicator, User programmable modes and more. We’ve taken hundreds of hours to analyse the feedback we received from field usage and implemented this knowledge into features that matter to you the most.
