RetraFlash PRO X 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 quality of light
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)
What's new:
Up to 25% faster recycle times and up to 20% more flashes per battery charge thanks to a optimised flash triggering system
New lightweight housing with an 8% reduction of total mass (all existing accessories remain compatible)
Redesigned optical sensing module with improved signal processing
Direct mounting for the E-Opto converter (no optical cable in between)
Improved TTL accuracy and TTL maximum power output (all existing converters remain compatible)
Reinforced mode and power dials in case of impact
Dedicated HSS mode on the control panel
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.
