The two ways of Calibur

Fencing made flexible: track hits on your own smart device with the Calibur App, or sync with standard scoring machines using the Relay.

Calibur App

The Portable Setup

By downloading the Calibur app to your smartphone or tablet (available for free on AppStore, Google Play, and Amazon), your own device becomes the scoreboard.

Who is this for?

We recommend this for fencers who want to practice outside of a traditional club environment. It is the perfect choice for:

home or outdoor training
fencing demo or school session
warming up at a competition

Relay

The Club Setup

The Relay works like a pair of reels: plug it in your traditional scorebox to make it compatible with our wireless technology. Ideal for a tidy and modern fencing hall.

Who is this for?

This is the best option for clubs to get rid of the cable-related repairs. We recommend it for clubs who:

want the freedom of wireless fencing
while training in a well-equipped hall

The Calibur App

For fencers who want a portable scoring setup without heavy equipment

Download the Calibur App from the App Store, Google Play, or Amazon. System requirements: iOS 15.1+ or Android 8.0+. Open the app and select your weapon (épée, foil, sabre or plastic foil).

Connect the Pocket Boxes: Press the white button on the first Pocket Box (the LED will turn blue). Tap the fencer icon on the left side of the app screen to pair it. Repeat this for the right side with the second box. Once connected, the LED turns green.

Plug your body wire into your Pocket Box. You are now ready to fence!

The Relay

It allows you to use your wireless setup with a traditional scoring machine

Connect the Relay to a power source (power bank or wall plug) to turn it on. Use the middle button on the device to select your weapon (Foil, Epee, or Sabre). You can also enable plastic foil mode by rapidly pushing the middle button three times in a row.

Turn on the Pocket Boxes by pressing their white buttons. The LEDs of the Relay will start as yellow, then turn green as each box connects. Once both boxes are paired, the LEDs on the Relay will turn blue.

Use two standard floor cables: plug one end of each wire into the sides of the Relay, and the other end into the scoring machine. (Note: You can also use épée body wires). That't it, you're ready to fence!

For sabre fencers

Due to the technical requirements of Sabre, you must use the Sabre Armband Set for the system to work correctly.

Put the armband on your bare upper arm. It is essential to have direct contact with your skin.

Snap the armband cable onto the metal stud on the armband. Plug the other end of the cable into the fourth socket of your Pocket Box.

Once both fencers have connected their armbands and paired their Pocket Boxes as described above, you are ready to start.
