Hi Tom, Thanks for the offer. The oldhams were such a good light but they have had a hard life, What are you guys using these days instead. Comming from WA i could always pick up parts from friends in the minning industry. I used to cave every 2nd weekend in WA but living in Melbourne its dropped to maybe twice every couple of years. Not enough i reckon! My favorite caving areas i have caved are SW/WA, Nullabor, and Tassie. I just need to kit up a bit more and id like to join you guys and your club.
