Opponents of the badger cull believe they will be able to better prevent marksmen shooting badgers by investing in thermal imaging cameras.
Anti-cull campaign group Gloucestershire Against Badger Shooting (GABS) raised more than £3,600 from badger ball towards a fighting fund, which it will use to try to prevent the deaths of badgers.
The money will go towards the purchase of thermal imaging equipment, which anti-culling patrols will use to try to locate badgers, particularly those wounded by any shooting.
Jeanne Berry, one of GABS' founder members, said: "The night was a fantastic success. The ball was over-subscribed with local people and supporters from across the country attending. The extra funds will help us with our wounded badger patrols."
