David Lafforthun's "The Annihilation of Trap-Shy Nuisance Beaver" DVD details a system never seen before on video. This system makes beaver as easy to trap as mice. This is a proven method of trapping beaver and cleaning them out fast. This technique is the best open-water system for fur trapping on the market, and will catch even the smartest of trap-shy beavers. Many trappers have a hard time catching educated beavers, resulting in time wasted on checking ineffective trap sets, and therefore creating an overall loss of profits. On the other hand, David's method alows you to clean out beaver colonies of 6-8 beavers within 2-3 days, using only four sets.
