Insert the punch pin to safety the F-bracket to the gimbal.
Cautionary Tip: When in low mode and
adjusting the camera position by sliding the
dovetail, be sure to support the camera.
An F-bracket is required for the gimbal, and this new arrangement of components must be
balanced, both statically and dynamically.
Traditionally, it’s considered harder to operate in low mode than in
high mode. Why?
Several factors may work together to make low mode
operating harder. The operator usually holds the sled further
from his body than in high mode. The operator’s hands are
not at the same height. Many times, the post is tilted from
vertical. The boom range is sometimes reduced. The rig may
not be in dynamic balance. The operator often cranes his neck
to see the image. In addition, every director wants the lens
height lower or higher than one can properly reach. And it’s
just plain weird to have the monitor so far above the lens.
Dynamic balance in low mode
Rebalancing is often ignored because it’s next to impossible to spin balance in low mode. But dynamic
balance is critical for precise work.
If the operator does not change the length of the sled or the monitor position, the sled remains in
dynamic balance when flipped to low mode. (Remember, the monitor flips on its center of gravity.)
If the operator changes the sled length and/or the monitor position, the Archer

sled must be
rebalanced dynamically.
Tip: Dynamically balance the sled with the camera and monitor upside down (high mode). Then as
your final step, move the gimbal away from the camera, so it hangs right side up in low mode.
But one still has to hold the camera further from one’s body, and the monitor is
still above the lens. So practice until low mode is as easy as.... it can be.
