The AcuteB is nothing less than a miracle. In an incredibly compact form (the size of a stack of VCR tapes) and weighing 4.8 kg (10.6 lbs), you still have a seven f-stop range of from 9– 600 Ws, the equivalent of 160 full power flashes per battery charge.
Using the AcuteB Head you can just put it all in a backpack and walk away, with nothing short of an entire studio on your back. The integrated radio slave module gives you full creative freedom, you can place the pack almost everywhere without any of the hassle and limitations created by the use of sync cables.
The bottom line?
You can – and will – bring high-quality light wherever you go.
