DF AnkleTag

Designed for multisport events. 

Introducing the DF AnkleTag, one of the latest RFID tags to come from the designers at Trident. This dual frequency tag offers far superior RF performance to earlier tags, due to it’s twin ferrite design giving no “dead spots” over the mat.

This tag comes with the option of Passive or Active. The Passive DF AnkleTag has no battery and relies on your DF HyperMat to transmit and receive the tag read. The Active DF AnkleTag has a battery that constantly powers the tag so that it is always transmitting – meaning less chance of missing a read when crossing the line at high speeds.

The Active DF AnkleTag tag comes in two different read rates, Active 16 is designed to send out 16 reads per second and Active 64 sends out 64 reads per second. Higher read rates gives extra security of getting a read from a fast moving athlete at multisport and cycling events.

The Active DF AnkleTag comes with a 4 year battery guarantee. If your tag runs out of battery prior to reaching 4 years we will give you a prorated discount on a replacement, eg: tag lasts 730 days out of an expected 1460: 730/1460 = 50% discount.

  • Robust waterproof construction (IP68)
  • Small form factor – just 40mm x 12mm x 9mm
  • Long read range 1.5m+
  • Twin ferrite construction gives no “dead spots” over the mat
  • Two convenient slots for easy insertion into Ankle Strap

We recommend using this tag at swimming or triathlon events where it is only possible to secure a tag to an athletes ankle using an Ankle Strap.

The Active 16 or 64 is perfect for timing cycling or mountain biking events.
