Tri-Tronics Field 90 G3 EXP

1-mile range; 6 continuous levels; 6 momentary levels; waterproof; audio tone; easy operation. This Field 90 G3 EXP is both simple and versatile. It's a perfect problem solver at home and all-around training tool for field work regardless of the type of training you do. The Field 90 is easy to use, with one button for each function - continuous stimulation, momentary stimulation, and tone. Six levels of intensity means plenty of adjustability for every type of dog. The Field 90 G3 EXP is field expandable to control up to three dogs (additional receivers/collars purchased separately). The unit comes complete with everything you need to train a single dog (transmitter, receiver/collar, charging cradles, power supply, product/training manual, DVD, and carrying case). To increase the number of dogs which can be controlled by the system, simply purchase the Tri-Tronics Accessory EXP Receiver(s) along with the corresponding collar straps. Extra optional chargers and charging cradles are also available. Quick and simple instructions allow you to marry the additional receiver(s) to the transmitter. ~
