From the Hottrax Championship Conditions
All competitors will be required to fit an AMB 260 Transponder (or equivalent) to their motorcycles for the purpose of accurate timing. They will be required to purchase or hire the transponder as a condition of entry. Competitors may be charged for the repair or replacement of Transponders and/or holders due to accident damage, loss or misuse at any time during the season. Transponders owned by the team may be used at no extra cost.
Transponder hire is £25 for a meeting and a bracket is available to purchase at £10 each. These are available at the circuit. Transponders must be fitted in the approved manor using the correct brackets for the transponder supplied. A deposit in cash of £40 is required which will be returned once the transponder is returned. This must be done within 30 minutes of the end of the last race or the deposit will be lost. No other electronic timing equipment may be placed within 5 metres of the Start / Finish line at any event. Any unofficial equipment placed within this area will be removed.
