Leakage Detection & Prevention The Retra Flash has a very low chance of leakage and even warns you if water ever enters the battery compartment. Built-in leakage detection Double O-ring protection Battery compartment waterproof sealed from electronics Circuit protection

The Pro Max has the highest power output of the new Retra Flash Series, a fresh OLED back panel display and offers the highest level of versatility that is appreciated by all underwater photographers. Engineered to Perfection For over a decade, a group of engineers and underwater photographers have teamed up with a single goal in mind: develop a true lighting tool for underwater photography. To reach this goal, we continuously examined feedback from photographers during every step of the development process. The end result is a travel friendly strobe that delivers top-tier performance in any lighting condition. So, whether you're a professional or just diving into the world of underwater photography, the Retra Flash will be your trusted companion on all your underwater adventures. 4th Generation of Underwater Strobe Technology With our 4th generation series, we listened to all your comments and made changes to the Retra Flash to better suit your needs. Electronics were completely redesigned with efficiency and performance in mind 4th Gen. Retra Flash uses less power for the same light output Optical triggering system is more reliable and able to read optical input even from sub-optimal fiber optic cables. Intuitive Back Panel Controls We've spent hundreds of hours analyzing feedback from photographers on the field and tweaking our designs to bring you a back panel you are immediately familiar with. We're also introducing a brand new innovation that is the centerpiece of the new Retra Flash Pro Max. The OLED display shows relevant information based on selected mode. The information is uncluttered and clearly displayed - even in sunny shallow waters! Information that can be seen on the display: Current mode Power setting Battery life indicator Capacitor recycle indicator And more! A reliable power source is the key Our 4th generation Retra Flash models have a completely redesigned battery compartment that can now hold 8x AA cells without the need for a separate battery compartment, when using the Booster. The Retra Flash is also the only underwater strobe with a built-in leakage detection system that warns you if water gets into the battery compartment. 

The Retra Flash Pure is a new addition to the Retra Flash family. The Pure is our entry level strobe, designed for anyone looking to dive into the world of underwater photography. The Retra Flash Pure features a smaller flash tube, which makes it a perfect match for the LSD snoot, allowing you to take breathtaking macro images. Performance in numbers Flash power: 70 Ws Power source: AA rechargeable batteries Circuit protection TTL Bluetooth connection Bayonet connection type: A1

Designed by underwater photographers for underwater photographers - with this in mind, Retra UWT has dedicated itself to developing 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 match. But it's not just about guide numbers. "All you need to remember about guide number is not to use it as a guide for buying a flash. 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 dispersed beam, but the latter is more desirable underwater." Alex Mustard in "Underwater Photography Masterclass " (2016) The user interface created by photographers. By listening to underwater photographers who have used the original Retra Flash, the developers 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 on battery compartment flooding. Therefore, Retra-UWT introduces a double O-ring on the battery cover and leak detector. In the unlikely event of battery compartment flooding, the Retra Flash will notify you to check the battery compartment as soon as possible.  Performance in numbers Flash power: 100 Ws Color temperature: 4900 K Pilot light output (angle): 300 lm (20º) Recycling time at 100% power (4x Eneloop pro): ~2 s HSS ready: YES Power levels: 13 Leakage warning device: YES Bayonet connection type: A1

Focus on quality of light Retra Flash is the world's first underwater flashgun with a fully circular flash tube. Combined with a completely new reflector design it produces a high quality light output no other flashgun this size can offer. It's not all about guide numbers. 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 User interface made by photographers We've spent hundreds of hours analysing photographers feedback from the field and tweaking our designs. The end result is a back panel you are immediately familiar with. Controls are large and tactile, for all types of hands or gloves. You will always get what you expected when using the control panel of the Retra Flash.  Underwater flashgun for the 21st century The new Retra Flash connects via bluetooth to your smartphone or tablet (patent pending technology). Check the status of your flashgun, set advanced features like HSS, Smart SL, Pilot Adjust and get firmware updates with the "Retra UWT" App. The new Retra Flash is a true system that is also built for the future.  Design your light without boundaries With the bayonet mount your Retra Flash can be transformed into a specialist lighting tool. Diffusers for blue water, green water and a special diffuser for sharks are available. For macro work there are several options to reduce the angle of the light beam. Secure mounting is the way.
