Big LED digits
Four LED panels side by side, one per digit, with the shooting pair on a panel of its own. Digits nearly 30 cm tall. Five brightness levels, set from your phone.
NockClock · Wireless LED archery timer by SBT
The archery timer with a clear countdown for every end.
A wireless LED archery timer for clubs and competitions. Big digits the whole line can read, run from the phone already in your pocket — no app to install, and no cables across the range.
Designed, developed and assembled in Britain · serviced in the UK · built to order in small batches
Green while shooting, amber for the last 30 seconds, red when time is up.
Features
Everything the shooting line needs. Nothing it doesn’t.
Competition sequences
A whole two-detail round from one Start: red preparation, green shooting, amber for the final 30 seconds, then the next pair. The lead pair rotates automatically.
Emergency stop
One press freezes the clock, flashes the display red and sounds the alarm. Resume carries on exactly where it stopped.
Nothing to install
No app, no accounts, no updates to chase. The control page is served by the display itself and works in any phone or tablet browser, on any make.
Control from your phone
The display makes its own Wi-Fi network. Join it and the control page opens by itself — big buttons, readable in daylight. Lock your phone or walk away and the round carries on regardless.
Buzzer and siren
A buzzer at the display plus a 12 V siren loud enough for the whole line. Mute the siren for indoor rounds with one tap.
Two displays, in step
The second display mirrors the first exactly — countdown, colours and messages — so a long line, or both ends of the field, can see the clock.
Messages between ends
Break and Delay countdowns, a Finished screen, and your own scrolling messages, sent at a tap.
Battery powered
Each display runs from its own 12 V lithium (LiFePO4) battery, with a bar on screen that warns you when it is getting low.
How it works
Set up in minutes
1
Place the displays
Stand them where the shooting line can see them and switch on. They run from their own batteries, so there is no mains cable to lay.
2
Join the Wi-Fi
Pick the timer’s network on your phone and the control page opens by itself. No app, no sign-in, and no internet needed at the field.
3
Start the round
Choose a sequence and press Start. Preparation, shooting and the next pair run on their own, with sound — you are free to watch the line.

Questions
Archery timer FAQ
What does an archery timer do?
It shows the shooting line how long is left to shoot each end, and signals when to come to the line, start shooting and stop. NockClock runs the whole sequence itself: red for preparation, green while shooting, amber for the final 30 seconds, and red when time is up, with the buzzer and siren marking each change.
Does it handle AB/CD details?
Yes. A two-detail round runs from one press of Start, and the lead pair (AB or CD) rotates automatically after each end. The pair shooting is shown on its own panel, and between ends the display shows who is up next.
Do I need an app, or internet at the field?
No to both. The display makes its own Wi-Fi network; join it on any phone or tablet and the control page opens in the browser. Nothing is installed, and no internet or mains power is needed at the range.
How far away can archers read it?
The digits are nearly 30 cm tall on a 640 × 320 mm LED face, sized to be read from the shooting line and the waiting line. With two displays in step, one can stand at each end of a long line.
Can it be used indoors?
Yes. The siren can be muted with one tap for indoor rounds, leaving the buzzer at the display, and the brightness has five levels.
Can we see it working before we order?
Yes. We bring the timer to clubs to demonstrate it, and deliver and set up every set in person, showing whoever will run it how it works.
Where is it made, and who services it?
NockClock is designed and developed in Britain — the electronics and the software that runs every sequence are our own — and each set is assembled and tested here by hand. Like almost all electronics, some parts, such as the LED panels and processor modules, come from specialist manufacturers overseas. Servicing and repairs are done in the UK, by the people who built it.
How much does it cost, and how long does it take?
£1,500 for a set of two displays — an introductory price on orders placed before 31 March 2027. Each set is built and tested to order, with a lead time of about six weeks. Schools, registered charities and clubs ordering more than one set can ask about pricing.
