Personally I believe they should be only allowed for use on private land, the same rules as spotlighting basically. While hunting in a favourite spot a few weeks back we had pick up a few animals by mid morning but nothing that we wanted to shoot when a guy turned up. not letting on about what we had seen (an still could) he unexpectedly pulled out a thermal an proceeded to go over the country we were looking at. Luckily it must have been to sunny or something as he never picked them up an eventually he went on his way. Now if he had been a young person or someone looking for their first deer or hadn't much experience that wasn't using a thermal then I would have happily pointed one out for them to try for after having a chat to them. but the way it happen it just never sat will with me an I cant say I felt guilty we he eventually bugged off to look elsewhere.
