I have a Petzel Zoom that I?ve used for about 7 years and a Petzel Tikka I got last year.
The Zoom has the Halogen bulb fitted this is the one I put in my bag if I?m fishing in the woods as it allows me to find my way out without falling on my arse all the time.(But I don?t use it for baiting up or rig tying) it's a superb heavy duty bit of kit but the battery only last about 8 hours with a standard bulb and only 4 with the Halogen. The Halogen bulb is so bright shine it in your mates face and that?s his night vision goosed for the next two weeks and it will put the swim down if you shine it onto the water, on one occasion I was actualy mistaken for a Helicopter landing pad
Zoom
Most of the time though I use a Tikka it's a great little head torch. The battery?s last ages 110 hours (I use rechargeable from Argos 4 for a fiver) and its light weight..
Tikka It has developed one crack where the head band goes through and one on the top near the button that you press to open the battery compartment, but this has not affected the usability of the torch.
If I could only have one it would be the Zoom with a standard bulb fitted it will do all I need and although it?s heavy on the head and heavy on the battery?s it?s indestructible and in the 7 years I?ve had it I've yet to find a fault with it.
