No, the Supercharger is only compatible with the Retra Flash Pro/Prime and Retra Flash ProX/Prime X models. 

If there are at least 2 millilitres of water inside the battery compartment of the Retra Flash, the built-in leakage detector will be triggered.

Follow all diving safety protocols and check the battery compartment at your earliest convenience. Remove the batteries and use fresh water and mild soap to clean the battery compartment after a flooding incident. 

• Check the battery compartment and battery compartment cap for any kind of indication of water or moisture. If you are using a Supercharger check for any kind of indication of water or moisture inside the Supercharger battery compartment as well.
• Position flashgun vertically with the dome facing down and check the front dome for any kind of indication of water or moisture inside the flashgun. If there is any kind of water present inside the flash DO NOT use the flash. Remove the batteries and contact us for assistance at: develop@retra-uwt.com.
• The battery surface may have come in contact with the housing due to damaged wrapping on the battery. Reposition your batteries and try again. If the problem persists batteries may need to be replaced.
• Upgrade Firmware.
• If the problem persists, but there is no water or moisture inside any part of the flashgun, Firmware is up to date and you are using new batteries, contact us for assistance at develop@retra-uwt.com.

We suggest lubricating o-rings every 10 times the battery compartment is opened/closed. We supply a silicone grease with the Retra Flash, however, any silicone grease suitable for EPDM can be used for lubrication.

Yes, the Light Shaping Device Ultimate consists of two modules;

- The optical tube that shapes the light and is the main component in the LSD,

- and the mounting module that can be exchanged to fit any strobe or flashgun.

You can change the mounting module on the LSD Prime and Ultimate models within minutes by removing the four screws that connect the optical tube and the mounting module.

This way, if you decide to change your strobes you don't need to buy the whole LSD again, only the mounting module.

In real situations, scratches on the glass of the optical tube have no visible impact on the light.

Always rinse your gear with fresh water and dry completely with a clean towel or rag before storing.
