From the Defra site on badger cull methods:
Lamping
19. The course must explain the technique, regulations and conditions concerning the use
of artificial lighting. This includes:
a. The need for landowner’s permission when shooting (preferably in writing);
b. Practical application of lamping;
c. The need for additional people when using artificial light;
d. Clarity on who must be licensed according to the tasks carried out;
e. Prohibited, authorised (licensed) and allowed (no specific licence needed) methods
of taking/killing badgers;
Use of Night Vision Equipment
20. The course must explain the technique, regulations and conditions concerning the use
of night vision (NV) equipment. This includes:
• Use at a range of no more than 60m over a fixed bait station, which is known to be
a safe, secure shooting location;
• Use from a fixed, preferably elevated, shooting position;
• Only Generation 2 or 3 Night Vision equipment with IR illumination must be used as
a rifle scope (or comparable digital NV equipment with IR); and
• A separate NV spotting device (also with IR illumination) and/or lamp must be used
by a second person to scan the wider area for unexpected non-targets, e.g.
livestock and members of the public.
It follows that night shooting using Night Vision equipment, as with use of a spotlight and
rifle, will also require a minimum team of two people.
