O-Ring-Set for battery compartment lid Pro Max/Prime+/Pure

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.
