I have 2 nightmasters, 1 permanently on the rifle (green LED) the other on a lanyard round the neck (white led) for spotting.
I think they are great, no coiled cables to get tangled, no big batteries to lug about.
How can a jimny be too small? its the size it is and does what it does very very well and thats, goes off road far beyond my Defender 90(expensive rough built leaking heap)would go.
I love mine its small but it doesnt claim to be big.
