STUNTMAN High Stability Chest Mount with Ball Joint for Action Cameras
Quick take
The STUNTMAN High Stability Chest Mount with Ball Joint is designed to steady an action camera or gimbal by combining a larger shock-absorbing chest plate with wide, elastic chest-and-shoulder straps. The ball joint makes it easy to aim and adjust height, which is especially useful when you lean forward on a bike. The main buying caveat: while it feels sturdy and secure, some riders do not see a big stability upgrade compared with a generic chest mount.
Pros and cons
Pros
- Wide base plate and shock-absorbing elastomer help reduce unwanted movement while you ride.
- Ball joint lets you point, adjust height, and offset the camera for a centered lens.
- Elastic chest and shoulder straps are described as high strength and designed to stay put during movement.
- Designed for common action-cam ecosystems, including GoPro, DJI Osmo Action models, and Insta360 (two-prong mount style).
Cons
- Video stability gains may be less dramatic than expected on rough trails, since chest mounting can still transmit vibration.
- Phone mounting needs a separate STUNTMAN smartphone adapter.
- Compatibility depends on the camera using the two-prong mount setup (not every action accessory will fit directly).
What buyers think
Buyer feedback centers on build quality, stability feeling, and how adjustable the setup is. Multiple reviews highlight that the mount feels secure during movement and that the wide chest plate helps keep the camera more settled compared with cheaper, flexible chest straps. Reviewers also commonly describe the ball-joint style adjustment as a practical advantage for aiming and positioning. There is some mixed evidence on the size of the stability improvement, with at least one rider saying the difference versus a generic chest mount was minimal on a compared trail, even though the mount still felt well made. Overall, buyer-review evidence supports the idea that this is a sturdy, versatile chest mount, with stability improvements that may vary depending on your activity and expectations.
Why a ball-joint chest mount matters for action video
Chest mounting is about controlling camera angle and reducing wobble from strap bounce. The STUNTMAN design combines a shock-absorbing elastomer base plate with a two-prong camera mount interface, then adds a ball joint to adjust where the camera points. That matters if you ride in a forward-leaning position, because the mount can be tilted to keep the horizon and framing more natural without forcing you into an upside-down setup.
Key features and how they affect real use
Wide chest plate and elastic strap layout
A larger, shock-absorbing base plate plus wide chest and shoulder straps are meant to distribute load and stay secure. Reviewers frequently contrast it with flimsy “bundle” chest straps that flop during running, and describe the STUNTMAN straps as more substantial and easier to adjust.
Ball joint adjustability for aiming and centering
The ball joint lets you direct the camera, adjust height, and offset it to help keep the lens centered. This is useful for dialing in framing across different activities, like biking, hiking, or pairing the mount with a gimbal setup. It also helps you match the camera to your body position so you spend less time correcting angle after you mount up.
Bike-friendly positioning
Because you often lean forward on a bicycle, the ball joint is intended to level the camera without remounting in an awkward orientation. If your goal is consistent horizon framing, this adjustability is a practical feature.
Compatibility notes: two-prong mounts and add-ons
The mount is designed for action cameras with a two-prong mounting system and is listed as compatible with GoPro (including HERO13, HERO12, HERO11, HERO10, HERO9/8, MAX, and Fusion) and DJI Osmo Action (Action 5 Pro, 4, 3, 2), as well as Insta360 models like Ace Pro, Ace, ONE RS, and ONE R. Smartphone and specialty camera setups require additional STUNTMAN adapters (sold separately), so plan for that if you want more than a standard action-cam fit.
Pros and cons (buyer-fit summary)
Who it’s best for
- Cyclists who want a secure, adjustable chest placement for an action camera or gimbal.
- People who frequently change camera framing and need aim/height flexibility.
- Buyers moving up from generic, lightweight chest straps that feel like they shift or flop.
Who should avoid or consider alternatives
- If you expect chest mounting alone to eliminate shake on rough trails, be aware stability gains may be smaller than hoped.
- If you need to mount a phone or non-standard devices, verify you have the right STUNTMAN adapter.
- If your camera accessory uses a different mounting method than the listed two-prong setup, you may need a different mount.
Performance expectations: what to realistically anticipate
This mount is built to feel secure, and the design choices (shock-absorbing elastomer plate, wide straps, ball-joint aiming) are aligned with reducing unwanted movement. Still, chest video is affected by your body motion, terrain, and how your camera setup handles vibration. If your use is bumpy and you rely heavily on stabilization, pairing the mount with the right camera settings (and, when needed, a gimbal) is often what determines how smooth the final footage looks.

Verdict
The STUNTMAN High Stability Chest Mount with Ball Joint is a good buy if you want a more secure, adjustable chest setup for GoPro, DJI Osmo Action, or Insta360 cameras. The wide strap and shock-absorbing plate design make it feel built for motion, and the ball joint helps you get the framing you want. If your main goal is maximum stability improvement on the roughest rides, expect results to depend on your route and stabilization setup, not just the mount.
FAQs
Is this chest mount compatible with GoPro and Insta360 cameras?
It is designed for action cameras that use a two-prong mount system, with compatibility listed for multiple GoPro models and several Insta360 models, including ONE RS and ONE R lines. If you have a different mounting style, you may need an adapter.
Does the ball joint help with forward-leaning activities like cycling?
Yes. The ball joint is intended to let you tilt and aim the camera so it stays level for forward-leaning positions without forcing an upside-down mount.
Will this mount dramatically reduce video shake on bumpy trails?
It is designed to feel secure and stable, but real-world stability improvements can vary. Some buyers report minimal difference versus generic chest mounts on the same trail, so expectations should be calibrated for terrain and your camera’s stabilization setup.
Can I mount a smartphone to this chest rig?
Phone mounting is not listed as standard. You’ll need a separate STUNTMAN smartphone adapter (sold separately) if you want to attach a phone.
What devices does it work with besides action cameras?
The mount can be used with other compatible setups, and additional STUNTMAN adapters are available for items like compact cameras with a tripod socket and wearable gimbals. You’ll want to confirm the adapter you choose matches your device’s mounting method.
How secure is it while running or moving?
Buyer feedback generally emphasizes that the straps and base plate hold the camera securely during motion. It is often preferred over flimsy, low-cost chest straps that can shift or flop.
