Breakaway Snare
Breakaway fox snares claim to break when holding non target species, such as badgers and deer, allowing them to escape uninjured.
There are a variety of different breakaway snares designs in the UK, some of which are copies of US snares. However by far the most popular breakaway fox snare is the DB Snare and you will rarely see other breakaway designs in actual use.
The Glenn Waters Breakaway Snare (photo above) is one variety of breakaway snare sold in the UK. In order to reduce costs it incorporates a half S-hook breakaway into the snare eye rather than having two separate pieces. It also lacks the Relax-A-Lock feature of the DB Snare. There is no data on how effective it is on releasing non target animals, yet it is permitted to be sold in the UK.
