SENTRY6 SLEEVE
An affordable 6-sensor Pitching Sleeve & Digital Coach
Lab-Grade Tech, Built for the Field
Data directly to your phone on the field or Deep-Dive Analysis on PC for a full biomechanical breakdown with side-by-side 3D model and video replay.
Extracted from the 18-sensor Suit
The "Slingshot" Focus:
We’ve distilled our full-body system down to the essentials, the hips, torso, and pitching arm
Pro Pedigree:
Sentry6 uses the same matured hardware and software as our $7,000 PITCHER3D, but in a simpler to wear, simpler to use package. The 30 years of science is well hidden away behind simple app screens.
Help Us Bring Our Working Prototypes To Market
3 levels of high performance sensors in 2 models, the Manager and the Pro. The sensors are upgradable by the user.

The Technology Pipeline
01
6-Sensor Array
Six high-fidelity IMUs ride the hips, torso, and pitching arm -the same matured hardware powering our $7,000 Pitcher3D suit, in a simpler-to-wear sleeve.
02
200Hz 3D Slingshot
Our Slingshot focus rebuilds your kinematic chain in 3D at 200Hz -pelvis fires, torso loads, arm releases. 30 years of biomechanics, hidden behind simple app screens.
03
Phone Field. PC Lab.
Get the call-out numbers on your phone between innings. Sit down at the PC later for the full deep-dive: side-by-side 3D model and video replay, pitch by pitch.
// 16 Measured Values Per Pitch
No vanity scores.
Just the physics your delivery is made of, like:
Showing 4 of 16
ARM_SLOT.DEG
Arm Slot
Vertical release angle relative to spine, pitch by pitch.
ROT_VEL.DEG_S
Shoulder Velocity
Peak internal rotation speed of the throwing shoulder
HIP_LEAD.MS
Hip-Torso Sep
Millisecond delta between pelvis and shoulder rotation -the slingshot.
REL_HEIGHT.M
Release Height
Exact height and extension of the elbow at release, every pitch.
// PC Deep-Dive
3D model + sync video,
complete biomechanical engine with relation graphics.
Get the call-out numbers on your phone between innings. Sit down at the PC later for a full biomechanical breakdown -elbow height, forearm tilt, joint tracking, all synced to your video.
// 3 Sensor Tiers ·
User Upgradable
Start where your budget lands. Upgrade the boards, not the sleeve.
Every Sentry6 Manager ships with six IMU sensors. Swap individual boards for higher gyro range as you progress: no new sleeve, harness, cabling, harness or processing hub.

Sentry6: Manager
The upgradable sleeve.
Six standard 2K and 1.5K sensors, which are accurate but not as fast as our top speed sensor. Start here for little leaguers where and grow into the 4K systems as velocities go higher.
Sentry6: Pro
The locked-in flagship.
Top-tier L3 sensors for high velocity action placed where needed (arm) and L1 where accuracy is the only objective and angular velocities never go higher than 1500 degrees/second.
Understanding the Sentry6 Ecosystem
Our hardware is built on an Open Sharing Model. A single Sentry6 sleeve can be shared across an unlimited number of players and coaches -the hardware is never locked to a single user account. You only choose the software tiers that match your workflow:

The Mobile Suite (On-the-Mound Tracking)
The LOG App (Free Subscription)
The essential data-capture bridge. It allows coaches or players to seamlessly record pitches, sync sensor data, and log captures directly from the mound.
The SEE App ($5/mo Subscription)
The mobile analysis engine. It instantly processes logged captures right on the field, providing immediate analysis, baseline comparisons, and player ranking metrics.
The Desktop Powerhouse (Laboratory Precision)
P3D BioMech PC App (Full-Featured License)
Our most powerful kinematic display engine. Built for deep-dive analytics, it allows unrestricted graphing flexibility, tracking complex multi-axis relationships between all joint and bone segments completely outside standard baseball points of interest.
"For decades, professional biomechanical data was locked behind $100,000 laboratory systems.
Sentry6 changes the game."
