RetraFlash PRO Underwater Strobe
Developed by underwater photographers for underwater photographers - with this claim Retra UWT has dedicated itself to the development of one of the best underwater flash units in the world.
Focus on light quality
With a unique flash tube design and a completely new reflector, Retra-UWT has achieved a light output that no other flash unit of this size can offer. But it is not only about guide numbers.
"All you need to remember about guide numbers is not to use them as a guide when buying a flash. The guide number is determined by both the light output and the spread of the beam. A focused beam produces a much higher guide number than a widely scattered beam, but the latter is more desirable underwater." Alex Mustard in the Underwater Photography Masterclass (2016)
The user interface created by photographers
By listening to underwater photographers using the original Retra Flash, the developers have optimized the user interface. The interaction and functionality of the new Retra Flash is even more intuitive and precise.
Double O-ring and leak detector for the battery compartment
Our goal is to achieve a 0% statistic for battery compartment flooding. Therefore we introduce a double O-ring on the battery cover and on the optional leak detector. In the unlikely event that the battery compartment is flooded, you will be notified by the Retra Flash to check the battery compartment as soon as possible.
