I’ve been using a Gamma for a couple of years having read about it on stever’s blog. Brilliant for the money and I thought if it breaks I’ll get another and can do that twice and still be quids in over the petzl.
Well, you must use duracell batteries. It does say that on the website. Mine has developed a switch fault which seems to make the batteries run out even when it’s not on and they get a bit hot . . .
So, last week I got a Maplin one for £15 which takes any old batteries. First impressions are that the beam is a bit narrow but I haven’t actually run with it yet. I can see I might end up buying another gamma though – especially if I can do the silver paper bodge ^^ for rechargeable batteries.
