Would appreciate some advice from the more clued up about the purchase of a decent head torch, as the one i am currently using which i won in a competition a good while ago has seen better days and i now wish to replace it, my main issue is that i want a decent, lightweight one that will not chew through batteries at an alarming rate, will be used for general activities, dog walking, and taken with me on hunting trips, doesn't have to be super heavy duty, just a decent light. I have looked at the Alpkit Gamma and Silva Twilite so far, any more suggestions? Budget up to £25 or a bit more if appropriate. Many thanks folks.
