Smart assignment
Multiple incidents at once. The app assigns the one most able to harm you where you stand, not just the nearest pin.
Cordon · Exposure · Approach
Know the cordon.
Know your exposure.
Before you step.
The Long Walk sizes physics-based standoff rings for every device on scene, assigns the one that matters most where you stand, and shows live blast and fragment exposure on your wrist as you close in.
Capabilities
Built for the last hundred metres.
Live exposure
Overpressure and fragment-hit probability update with every step, so you read your real risk as the distance closes.
Physics-based rings
K50 and K328 standoff from scaled-distance criteria, air-blast decay, and fragment hazard range, floored at the published minimum.
Phone to watch
Enter the picture on the phone, push it to the watch over Garmin Connect. No network needed in the field.
How it works
Three steps from intake to wrist.
Step 01
Enter the incidents
Add each device with its location, charge, and casing. The companion computes the cordon rings as you type.
Step 02
Push to the watch
Send the full list to the watch over Garmin Connect. The active incident is chosen for your position.
Step 03
Approach with the picture
The watch homes to the incident, shows the zone you are in, and your live exposure. Cycle incidents from the wrist.
The science
Every number is documented.
The calculations behind The Long Walk are set out in full, with derivations, figures generated from the shipped models, and references. The papers reproduce the standard tools where they apply, and extend them where fragmentation governs.
