The xR3ACH is a groundbreaking new hybrid back mount, that not only serves as a back mount but also acts as a single section articulated stabilization arm.
It’s an evolution of our fixed back mount, the xBONE, adding technology from our xARM and the result is a very robust hybrid backmount, with a small footprint that can take loads up to 29 kg/64 lbs *(See note below).
The boom range of the xR3ACH is 390 mm/15.3 inches, so when used in combination with the xARM, you get a total boom range of 120 cm/47 inches.
MOUNTING OPTIONS AND ADJUSTMENTS
The xR3ACH is back mounted and fits Tiffens Steadicam Fawcett Exovest, the Walter Klassen Flex and the Action Products Vest. Mounting hardware is supplied for one of the vests, which you choose upon order.
It ships with three middle brackets of different sizes (S, M and L), used to fine-tune the position of the socket block, to ensure great fit for your specific vest and body type. The brackets can be mounted in fixed angles of 22.5 degrees, to further fine tune the set up.
It features a fully adjustable x-y socket block stage. The tilt angle is adjusted with a large knob, and the roll is adjusted like any usual socket block by two knobs. The roll adjustment on the xR3ACH socket block has a larger degree of adjustment than most other socket blocks on the market.
xR3ach Spring Cores
The xR3ACH is based on the same type of polymer spring cores used in the xARM, with an outer shell of Neoprene. Each spring core has a smooth and linear lifting capacity, and when being used near their maximum, they perform their best. Because of this, each spring core has a weight range of about 5 kg/11 lbs, allowing the operator to fine tune the arm to optimal performance. The xR3ACH normally ships with three different spring cores (Blue, Orange and Purple), to cover a range between 17-29 kg/37-64 lbs *(See note below). The spring cores are pre-extended and can be quickly changed when needed. The xR3ACH will give the operator a new idea of what it means to work fluently and smoothly with a minimal force needed to maintain any position.
THE XR3ACH SHIPS DEFAULT WITH THE FOLLOWING THREE SPRING CORES:
• Blue 17-22.5 kg / 37-49.5 lbs
• Orange 20-25.5 kg / 44.5-56 lbs
• Purple 23.5-29 kg / 52-64 lbs
FOR LIGHTER SETUPS THERE ARE ALSO TWO LIGHTER SPRING CORES AVAILABLE:
• Green 14-19.5 kg / 31-43 lbs
• Teal 8-14 kg / 17.5-31 lbs
