DST Training · App

Your training ground in your pocket.

The DST Training app connects your smartphone or tablet to the light barriers via Bluetooth. Every pass appears instantly on the monitor – with measured time, target time and deviation.

  • Monitor: all passes live, with colour-coded deviation from the target time
  • Course layout: several light barriers in a row, each with its own target time
  • Storage: save series of runs and compare them later
  • Configuration: e.g. lockout time against double triggering
  • Privacy: all data stays on your device – no cloud, no tracking

Draft: add Google Play link once available.

Built tough for the outdoors.

Our DST components come in signal colours so they stand out at the course immediately. Everything fits into a lockable case – the tripods travel in their own bag.

DST light barrier, yellow, with antenna

Light barrier module

Timing module with its own GPS-synchronised clock: captures the time right at the timing point. Alignment mode with beep, OLED display, battery with USB-C.

DST central module, red, with antenna

Central module

Receives the times from up to 6 timing modules by radio (max. 150 m radius), confirms each one individually and forwards them via Bluetooth to the app or tablet.

DST emitter, yellow

Emitter

Counterpart to the light barrier on the other side of the track. Instead of using a reflector, the emitter sends the light beam itself – for passage widths of up to 20 m.

DST pressure hose module on a tripod with hose

Pressure hose module

Timing module with the same time capture – triggered by a hose laid across the course.

Aluminium case with light barriers, emitters and central module

Everything in one case

Scope of delivery: 2 light barriers incl. emitters, central module and double batteries – stowed safely in an aluminium case with foam insert.

Carry bag with stainless steel tripods and marker flag

Tripods & flags

Stainless steel tripods and marker flags in a robust carry bag.

Technical data

Time resolution1 µs, hardware capture *
Light barrierDistance to emitter max. 20 m
Radio rangemax. 150 m radius around the central module, i.e. max. 300 m diameter
Timing modulesmax. 6 per central module (light barrier and pressure hose modules)
RadioWiFi to the central module (channels 1–13), Bluetooth Low Energy to app or tablet
Transmissionacknowledged, with retries; buffer for 5 times (timing module) and 64 (central module)
Parallel operationGroup ID 1–255 separates several systems at the same location
Interference filterMinimum trigger duration 0–5000 ms, lockout after triggering 0–10000 ms
OperationOLED display, rotary switch, beep
Power supplyBattery, charging via USB-C

* Resolution of the digital capture. The achievable accuracy of the overall system depends on GPS reception, light barrier and setup, among other things. Timing modules need a clear view of the sky.
