The Delta Upland XC Dog Training Device package was designed specifically for upland hunters and comes packed with features to give you the most out of your hunts and training sessions. It features an ergonomically designed, 3-button controller with an LCD display and only requires one hand to use, allowing you to keep your eyes on your dogs. This controller can sync up to 3 collars for training multiple dogs as the same time (additional collars sold separately), and lets the user select between 5 correction configurations and choose the best option suited to the situation and dog temperament. These options feature 36 levels of continuous or momentary stimulation, as well as audible tone and vibration. The Delta Upland XC also features the integrated BarkLimiter with Advanced Bark Correction. This feature recognizes the difference between wanted and unwanted barks, as well as vibration from scratching and scraping or from other dogs’ barks to prevent false and over correction. In addition, the Delta Upland XC features a lightweight upland beeper that can produce 4 hunt sounds (including silent) and 2 point sounds (including a hawk scream) to help you locate your dog and to know when he’s on point.
