Understanding how HIT works for you?
A minimal introduction to the technology, what it does, and how it supports safer decisions after a head impact.
Precision
in every
impact.
In the world of safety, precision matters. HIT technology transforms complex data into actionable insight. Using metrics like G-force, rad/s and cumulative G-force load, HIT doesn't just count the impacts — it translates them.
Research from leading experts, including Rowson & Duma (2013), shows that the combination of linear and rotational forces is the most accurate predictor of concussion risk. That's why HIT tracks both metrics in every impact.
By combining these data points, HIT provides a clearer, more reliable view of brain stress and fatigue — helping athletes, parents, and coaches make smarter decisions about when to rest, recover, or continue training.
Rowson & Duma, 2013 — Concussion Risk Prediction via Linear & Rotational Acceleration
No single measurement
tells the full story.
Measures straight-line impact forces — like a direct blow to the front, back, or side of the head. The higher the G-force, the greater the linear acceleration experienced by the brain.
High G-force events are linked to bruising, skull fractures, and focal brain injuries.
Common in high-speed sports or direct collisions — cycling, rugby, equestrian, and snowsports.
HIT logs every G-force event in real time, alerting when thresholds are exceeded.
Measures rotational velocity — how fast the head spins after an impact. Rotational forces are widely considered the primary driver of diffuse brain injuries and concussion.
Rotational forces cause the brain to twist inside the skull — the leading cause of concussion and DAI.
An impact can have low G-force but dangerous rad/s — invisible to G-force measurement alone.
HIT tracks rad/s alongside G-force on every single impact for a complete picture.
Tracks the total accumulated impact load over time — across a session, a week, or an entire season. Even sub-concussive hits add up and can cause long-term harm.
Repeated sub-concussive impacts — none dangerous alone — can accumulate into serious long-term risk.
HIT monitors load across every session — helping coaches and parents spot fatigue before it becomes injury.
Cumulative load data supports smarter rest and recovery decisions throughout the season.
(Gravitational Force)
A measure of linear acceleration — how quickly the head speeds up or slows down in a straight line during an impact.
G-Force Load
The total accumulated impact load over time — tracking how repeated sub-concussive hits build up across a session or season.
(Radians Per Second)
Measures rotational velocity — how fast the head spins after an impact. The primary driver of diffuse brain injury and concussion risk.

Safety Features.
When signing up, users add an emergency contact and set an adjustable impact threshold. If a crash exceeds this threshold, the device sends a text with the user's last known location to their contact. A 45-second window allows the user to cancel the alert.
Users can share their data with up to three trusted individuals, allowing them to follow movement and progress directly through the platform upon saving activity to the Logbook.
