Surplus to requirements: Speleo Technics FX-ion battery in good condition, strap and short cable for rear helmet mounting, headset contains brand new 7 LED reflector and halogen bulb.  Complete with charger for FX-ion battery.  £50 for the complete system.  (List price is at least 3 times this, from memory - but look it up yourself.)

It'd be easiest for me to meet a buyer in the Dales and just exchange for cash.  (Or I sometimes cave in the Peak District, usually from Castleton.)

Please PM me if interested.

This is now sold.
