There is however some interpretation required to define "relaxing"
Every CO I have talked to won't (or can't) give a clear answer as to what this actually means or which products are or are not "relaxing" locks
regulations read as follows: ================================
Snares
It is only legal to use a snare to trap a wild animal on land you own or with the written permission of the landowner. The maximum legal circumference for snare loops is 15 inches, unless at least half of the snare loop is covered by water or if the snare employs a relaxing snare lock. A relaxing snare lock allows the snare loop to loosen slightly to reduce the possibility of strangulation. Regulations on snare size and lock are designed to prevent accidental loss of domestic animals.
