I've used the Pro 100 forever. The 200 doesn't fit the way I train - don't have much use for momentary stim.
100 and 500 are top flight systems. I still have two old 100s that still work fine, and I've updated only because the G series is a smaller transmitter and can control multiple collars.
The only difference you get with the 500 vs the 100, is the 500 will operate multiple collars, and other remote recievers - like wingers if you have TT recievers. I have Innotek receivers on my launchers with a separate multi-station transmitter, so for me there's no practical need to pay the difference for the 500 collar.
Just think!... the difference in price will buy me a whole tank of diesel for my truck! OUch......hurts to think of it that way.
Maybe you should outline your goals. If you are going to be a seasonal duck hunter for a few weekends per year then the sport model may be for you.
But if you are going to get serious about training and run hunt tests, etc, then one of the more advanced models would be best. I would highly recommend the Flyway model. The Flyway has hunting colors for straps and matte finish buckles.
100 has 16 levels cont. and 6 momentary. i just got a 100 myself. the 200 is the opposite and the 500 has 16 levels for both. i really like the 100 cause of the price. i think you can get a reman for around 345 or so, new around 447 and the 500 is like 505 or so.
Mr. Wayne thanks for your advice. I've come to a conclusion that I will think back to this past year and focus on her main problems. She is a high energy dog and knows alot just don't have much control over her. I would like to send you a private message but I don't have enough post yet. My email is [email protected] if you could send me an email so I could get your email I have a few questions for you. Thanks in advance Donnie
