Optimal arm height on the vest body and its effect on sled balance and control
DisputedParticipants disagreed and reached no conclusion. Read the findings as positions, not as an answer.
What the thread found
- Many operators position the arm lower toward the hip, with the chest plate aligned toward the navel, bringing the load closer to the body's center of gravity for greater stability.
- Arm height on the body does not change the balance of the sled itself.
- Arm height should be chosen based on lens requirements: a higher lens calls for a higher arm position, and vice versa.
- Load the arm so it stands slightly below horizontal; the operating hand then delivers a gentle upward impulse.
- Several operators run both arm sections angled slightly downward to prevent spring rebound; one account states that spring arms work optimally at approximately 10 degrees downward, while iso-elastic arms tolerate near-horizontal positioning.
- Different vest models place the socket block at different heights; most are adjustable or adaptable via aftermarket parts.
- Multiple operators recommend attending a professional workshop to learn proper setup.
Depends on
- Arm height preference varies among operators; higher versus lower positioning involves both personal comfort and the specific rig configuration.
