Transform your dog training experience with this advanced electronic training collar system. Featuring three effective training modes - beep (1-3 levels), vibration (1-16 levels), and static (1-99 levels) - this collar helps establish clear communication with your pet. The compact receiver measures just 2.3 x 1.4 x 1 inches and weighs only 0.12 pounds, making it comfortable for dogs from 8 to 120 pounds. With an impressive range of up to 1600 feet and dual-channel capability for training two dogs simultaneously, this collar offers exceptional versatility. The IPX7 waterproof receiver ensures reliable performance during outdoor activities, while the rechargeable lithium battery provides 11-15 days of use per charge for the receiver and over a month for the remote. The adjustable nylon collar fits neck sizes from 6 to 27 inches, and the ergonomic remote design ensures easy handling during training sessions. The quick 2-3 hour charging time keeps you ready for training, though initial charging requires 4 hours for optimal performance.
