The Booster is a singular piece that increases the performance of the 4th generation Retra Flash models (Pro Max, Prime +, Pure) by giving space for 8x rechargeable AA batteries.
The Booster doubles battery life and reduces the recycle time by more than 50%. Once mounted it is very secure so you can hold on to it while adjusting the strobe underwater.
