1. Initial Synchronization
1
Ensure Bluetooth is enabled on both smartphone and WearOS device.
2
Open ONESHOT on Mobile > Settings > "Sync to WearOS".
3
Select your rifle profiles and ammo loads to transfer.
Note: Standalone mode allows the watch to function without the phone after initial sync.
2. Environmental Calibration
For accurate POH, the watch must calibrate its internal sensors:
| Sensor | Calibration Action | Ballistic Impact |
|---|
| Barometer | Stay still for 5s | Density Altitude (DA) |
| Magnetometer | "Figure 8" motion | Coriolis & Eötvös Effect |
| Bluetooth | Connect Chrono | Real-time Muzzle Velocity |
3. Field Operation Workflow
A
Range: Input distance via crown or voice command.
B
Wind: Set 9 o'clock / 3 o'clock average and peak gusts.
C
Solve: Watch executes 10,000 Monte Carlo iterations locally.
D
Hold: Display shows Drop (MIL/MOA) and POH (%).
4. Haptic Wind Indicators (Advanced)
Configure haptic pulses to communicate wind holds without breaking cheek weld:
- Short Pulse: 0.1 MIL Left
- Long Pulse: 0.5 MIL Left
- Double Tap: Solution Updated (DA Change > 50ft)
5. Battery Optimization
To maximize battery during a 12-hour hunting session:
- Enable "Always-on Display: Minimalist Mode"
- Disable Wi-Fi (Use Bluetooth LE only)
- Set POH Refresh to "Manual" or "On Motion"
