The CapturePro with Proplate is an ingenious system. Holder suitable for both Arca and for Manfrotto. The Manfrottosystem can be adapted to the standard moderate Arcasystem a few easy steps and enclosed tool attach. Unfortunately, Allen is a little soft. But sends for assembly. The system maintains both good on the belt and the backpack. To fasten the belt should only remember that clearly draw a DSLR with a heavy lens and battery grip on his trousers but. So tighten our belts :-)
