TESTIMONIALS

– David Benz, Art & Water Photography
"For me, the Retra Flash Pro X is a real gamechanger. So much power and such simple and really well thought-out handling. Now underwater photography is even more fun."

– William Gladstone, Emeritus Professor
"My Retra strobes give me an unparalleled quality of light underwater. This comes from their beautifully uniform beam, reliable firing and colour temperature, the intuitive power setting steps, and the battery life."

– Magali Marquez, PADI / SNSI Instructor
"I feel confident using the Retra Pro strobe because it gives me peace of mind knowing that it detects moisture and tells me when I have a low battery.
After having worked with different strobes, I can say that the Retra Pro strobe along with the Retra LSD snoot has been a winning combination for my photography."

– Daniel Norwood, Dive Photo Guide
"After several months of constant use, I have nothing but good things to say about the Retra Flash PRO, and they have now become my go-to flashgun for the majority of my underwater photography work."

– Nicolas Remy, UWP Magazine
"I would buy them again if presented with the same choice."

– Mike Bartick, Award-winning Marine Wildlife Photographer
"The reflector is fun to use and perfectly suited for all-around use, including macro, wide angle, close focus wide angle, and oh yeah, blackwater!"

– Walt Stearns, Scuba Diver Destinations
"With the Retra Flash Prime, the quality and consistency of the light on subjects I was seeing was far more pleasing. The lighting from the Prime’s fully circular flash tube was impressively even."

Light Shaping Device
An accessory worth a special mention is the Retra Light Shaping Device (LSD). Due to its modular design, the Light Shaping Device can be easily paired with other flash devices by simply changing the mounting module.
When paired with the Retra Flash, you can also turn on the guide or modeling light on the strobe to see exactly where you're aiming your snoot. This way, there's no guesswork involved when positioning your flash light.
And with the extra slot for inserting different masks, you can easily control the diameter and shape of your light, giving you endless creative potential.

The Booster powers up your Retra Flash by giving space for 8x rechargeable AA batteries, that doubles battery life and reduces recycle time by half.
The new Booster is a singular piece that reduces chances of leakage and allows quick and easy exchange of the lid and batteries.
The new design is 50% lighter compared to the previous models of Supercharger.
Its lightweight and compact design, paired with the built-in leakage detection system, make it a must-have accessory for the 4th generation Retra Flash.
