The Pro 550 is a training collar only. If you are looking for a similar training system that also has GPS tracking, check out the Garmin Pro 550 PLUS.
"Take the best collar we sell, the Pro 500, add built-in beacon lights and a bark collar, then add 3 more STIM levels to the top end, add vibration, and then knock $110 off the price. That's the new Pro 550."
The PRO 550 is the perfect training collar for folks looking for a system that has it all.
Like the other two Pro Series collars, it has built in BEACON LIGHTS and a BARK LIMITER.
Both Kinds of STIM:
Gone are the days of having to pick between more momentary or more continuous. The PRO 550 has it all and at a substantially lower retail price.
Tone and Vibration:
The Garmin PRO 550 is the first Tri-Tronics tube unit to include vibration selectable from the transmitter with the V on the dial.
More STIM levels:
The PRO 550 is a 21 level training collar. The smooth transition between stimulation levels allows you to gradually increase stimulation and find the exact level that your dog needs. The three new levels at the top make sure you have enough top-end to train even the highest-intensity dogs.
The PRO 550 replaces the Field 90, Flyway Special, Pro 100, Pro 200, Pro 500 and the Upland Special.
