What it does

The shot timer integration connects MyKit.info to an SG Global Smart Shot Timer over Web Bluetooth. You never tap a submit button at the range — the flow is:
  1. Pair your timer from the Profile page once per session.
  2. Select a drill on the Range Day Drills tab — a Timer button appears on each drill when a timer is connected.
  3. Pick a firearm (optional) and the app switches to the Performance tab for that drill.
  4. Run the drill — hit the physical start button on the timer, shoot, stop.
  5. Results submit automatically when the timer stops and appear live in the Performance tab.

​
Browser support

Web Bluetooth is required. Supported environments: iOS support is planned via the Expo mobile companion app.

​
How results are stored

Shot timer results share the same range_drill_results table as manually logged and watch-sourced results. They are tagged source = shot_timer and show a Shot Timer badge in the Performance tab. Per-shot split times are stored alongside each result and expandable in the results list.
The passed_par flag is computed server-side from the drill’s par time — the same logic used for watch and manual results.

​
Pairing

​
Supported devices

The integration works with the SG Global Smart Shot Timer (Sport and GO models). The timer advertises via Bluetooth as SG-SST4A… (Sport) or SG-SST4B… (GO). MyKit scans for any device whose name starts with SG-SST4.

​
Connect your timer

  1. Open Profile (/dashboard/profile).
  2. Scroll to the Shot Timer section — above Connected Watches.
  3. Click Pair Timer.
  4. A browser Bluetooth picker appears — power on your SG timer and select it from the list.
  5. The section updates to show ● Connected · <device name> once the link is established.
Chrome requires Bluetooth permission the first time. If the picker appears but the timer isn’t listed, make sure the timer is powered on and within ~10 m.

​
Disconnect

Click Disconnect in the Shot Timer section of the Profile page. The connection is session-scoped — it clears automatically when you close or refresh the tab.

​
Connection scope

Web Bluetooth connections are tied to the browser tab. Pairing on the Profile page establishes a connection that persists across client-side navigation (Range Day, Performance tab, etc.) for the duration of the session. If you navigate to an external page or refresh, you will need to pair again.

Pairing troubleshooting

​
At-Range Workflow

​
Before you head to the range

  • Make sure you’re using Chrome on Android or desktop Chrome.
  • Create the drill in Range Day if you haven’t already (name, par time, round count).
  • Add the firearm you’ll be shooting in the Armory.

​
Step-by-step

1

Pair your timer

Open Profile → Shot Timer and click Pair Timer. Select your SG timer from the Bluetooth picker. The section shows ● Connected once linked.
2

Go to Range Day → Drills

Navigate to Range Day and open the Drills tab. Each drill now shows a blue Timer button alongside Watch and Log.
3

Click Timer on your drill

A firearm picker appears. Select the firearm you’re shooting (or leave it blank) and click Start.
4

Wait for the Performance tab

The app switches to the Performance tab for that drill, filtered to your selected firearm, and shows a ● Live indicator.
5

Shoot the drill

Hit the physical start button on your SG timer. Shoot. The timer stops automatically (or you stop it manually).
6

Result appears automatically

MyKit receives the SESSION_STOPPED event over Bluetooth, saves the result, and it appears in the Performance tab immediately — no tapping required.
7

Repeat

Hit the timer button again for the next rep. Results keep streaming in as long as the Bluetooth connection is active.

​
PAR time

If the selected drill has a PAR time set, MyKit writes it to the timer’s PAR setup before the session so the timer beeps at par automatically. No manual configuration on the timer is required.

​
Adding notes

Notes are added after the fact — not at the range. From the Performance tab, click Edit on any result and enter notes in the form.

​
Session reset

The active drill and firearm selection clears when you navigate away from Range Day or disconnect the timer. To start a new drill, click the Timer button on a different drill from the Drills tab.

iOS / Safari

Web Bluetooth is not supported on iOS Safari or any iOS browser. The shot timer feature is unavailable on iPhone and iPad until the Expo mobile app ships. Use Chrome on an Android device or a laptop at the range.

Still stuck?

Open the browser developer console (F12 → Console) and look for errors prefixed with BLE or shot-timer. Share those with support.
