I'd been agonising over choosing a scope-mounted gun light, getting bogged down with specifications, beam length, duration etc. etc. The rabbits here are now very wary and come out at night only. I was confused and becoming more reluctant to part with my money in case I made the wrong choice. Just before Christmas I walked into my local farmers' supplies stores for something else when I saw a Cluson box containing the MLS-1 Masterlight kit. At the salesman's insistence (I didn't need much persuading) I opened the box and had a good look. With the vat. knocked off, I persuaded my wife to buy it as a present. How glad I am I bought it!! Superb, bomb proof, excellent beam. The scope clamp is excellent, if not the most elegant, but it makes for speedy mounting/dismounting, with minimum faffing adjusting the beam when you set it up again. Highly recommended. Rabbits' eyes really shine when locked on. I find beam length statistics for lamps a little superfluous here on the west coast. There is often so much moisture in the air at night that, after a certain distance, all you can see is a fog of water droplets.
Is it worth investing in filters I wonder, and which colours work best in which circumstances?
