The PRO 550 with proven Tri-Tronics technology allows advanced training for the serious professional with easy access to 21 levels of momentary and continuous stimulation, tone as well as the ability to quickly switch between 3 dogs. PRO 550 features vibration and tone settings, remotely operated beacon lights on the dog device to help locate your dog in low light, the ability to add an Upland Beeper (purchased separately), and a built-in BarkLimiter, activated on the dog device, to help keep the peace at home.
Key Features:

• Classic, Rugged Design. The PRO 550 uses the tried and true tube-shaped design that trainers have come to love, but is easy to operate (and master) 1-handed so you can keep your eyes on your dog at all times, even while switching between stimulation levels and dogs. The stimulation level/vibrate selection dial is at the top of the transmitter, allowing intuitive operation. Tone, beacon lights and beeper are controlled using the switch,and buttons on the face of the handheld unit. And the control buttons comfortably line up in the hand for fingertip control. A 2 ½-inch fixed transmitter antenna eliminates the threat of a lost or broken antenna while delivering up to 1 mile range.
• Train with Stimulation and Tone. Choose from 21 levels of continuous and momentary stimulation, tone, and vibration for up to 3 dogs at a time (additional dog devices required; purchase separately). You can also remotely operate the LED beacon lights, built-in to the dog device, and an accessory beeper (purchase separately) to help locate your dog in low light conditions.
• Built-in BarkLimiter. PRO 550 features a built-in BarkLimiter, activated by the dog device. BarkLimiter features Autorise technology, which automatically adjusts correction to the optimum level needed to stop unwanted barking.
• Tough, Water-resistant, Long-lasting. Both the transmitter and the dog device collar are designed to withstand all the blows, bumps and sloppy conditions of training and hunting. The dog device comes with 2 sizes of removable, stainless, insulated contact points for reliable performance in wet conditions and extended comfort for the dog. The dog device is water-rated to 1 ATM (10 meters). The PRO 550 transmitter itself is water-rated to IPX7. The transmitter and dog device both feature a long-lasting, rechargeable, lithium-ion battery. A battery life indicator on the transmitter and dog device lets you know when to recharge the system.
