TT Pro 500 is my choice. Had the rest ,got the best. :)
The Flyway in more than enough collar to train your retriever .
I have had Pro 100, 200, and 500, but use my Flyway 90% of the time. I do not use the constant button much and if I do I don't need 18 different levels of it so the Flyway fits my needs.
I prefer the pro 500 because of the 18 levels of continuos...it's nice to have the 18 when force training. I have had friends and club members use mine instead of their flyways when doing force drills.
As a pheasant hunter I hate the toggle switch on the TT's. I had the old style pro 200 (single) for about 15 years, it was very good.
At the suggestion of Warner Smith at Garmin/Tri-Tronics, I now also have a classic 70. The classic 70 I use as a mile long leash that won't wrap around trees for pack dog walks numbering greater than 3 dogs. It has been absolutely perfect for instantaneous selection of the specific dog that I want to reach. The other 2 were fine when I was handling only 3 dogs. But with more than 3, the 70 has proven to be a great tool.
There is no one perfect choice for all trainers, all situations, and all dogs.
Some trainers prefer to reside in the continuous mode. For them, they may prefer the instantaneous ability to go high, med or low. For them, they flyway may not be best.
One problem that I see is that trainers can evolve or have their needs change. An example is myself, now seeking to handle 4 dogs simultaneously.
I view my transmitter selection a bit like any other tool. I can switch and adapt to match the tool with the job.
If I were seeking a one size fits all choice, I would choose to pay the extra and go with the g3 pro 500
My favorite is the Tritronics Pro 500. I have had mine for 5 years and never had a problem with it. Unfortunately, I recently lost the transmitter in the fields of South Dakota. Mine was the G2 model. I plan to replace it with a Pro 500 G3. In addition to the reliability and versatility, I like that it is made in the USA and I will always buy American when I can, particlarly when it is a superior product.
Thanks for all the responses. The issue I am having with my current collar with a full charged - I will have times with no stimulation, the too much and times the proper amount. Tested on myself, couldn't talk my son in to helping out as test dummy! I got the SportDog on a recommendation of a friend but have since read that others have had similar issues and they tend to continue to occur. I have sent mine back and customer service has been very friendly. Leaning towards a TT in the future. My training buddies have a mixed bag and they concur with what has been said here. Thanks again and Merry Christmas.
I would like to hear from those who have used the Tritronics G3 sport versions. I currently use a Pro 500 for training but in a hunting environment, the transmitter can be a bit of a pain. A transmitter that can be attached to a lanyard seems much more accessible. I'd be willing to give up a half mile of range for convenience, especially while hunting ducks where retrieves are generally 100 yards or less.
Bottom line, are you looking for a training collar or hunting collar?
