I know absolutely nothing about night shooting equipment other than what I own at the moment which is a fairly large Deben light which clips on top of the scope - this connects to a heavy battery with a switch in between. Yes I've shot lots of rabbits using it but it is cumbersome. It's so long since the battery was used (it's been in storage pending the purchase of a house) it's now probably knackered. So I've been looking at various YouTube footage and the IR stuff has caught my imagination - but I know nothing at all about it, all I can say is that some time ago I bumped in to advertisements suggesting one bit of kit or another - all about £2000 to £4000 (no thanks). Is there some reading up I can do on the subject to get with it - I've Googled but I can't get past heavy scientific stuff which is too deep for my requirements.

Assuming there are some suggestions are there any recommendations for off the shelf kits please?

Thanks
