I have a swarovski 2-12x50 z6i scope bought about 3 years ago. After 12 months the battery went flat. Over the last 2 years I have gone through about 4 more bateries. Been onto the shop where i purchased this and they say send it back to Swarovski uk. Not the best time to be without a scope and only one rifle for deer. Has anybody had the same problem? and if so did it need to go back or did they sort it out?Also been told that if I keep using it then I could burn out the illuminated reticle.
