Matt Weber. Chesapeake, VA. 5 out of 5 02.13.2017 at 2:15 pm If you want the best for your hunting partner then the 550 is for you! You really do get what you pay for. This system has tons of options and is easy to use. DEPENDABILITY!! The staff at outdoor dog supply is first class. Knowledgeable and honest. In a 60 day duck season I hunt 50+ days and a Garmin pro 550 is around my dogs neck on all of them!
