thats just old fashioned nonsense , the only real problem with new snares is that they are more visible, to any prowler , but once they weather , and set well out they are extremely hard to see. i set out 100 brand new pegged snares . one morning and had rabbits the following morning. woodga set a hundred out not so long ago and took a good few in the evening just before dark , then took a kill in the morning , the overall total between evening and morning was nearly a hundred rabbits , all from new shiny brass snares.
