I have the Flyway G3, train with it and hunt with it. As others have said i attach mine to the strap of my waders using an avery holster and works great.

I've had many, including very nice TTs, but moved to (2) Dogtra 1800's about 10 yrs ago when I had trouble with a pre-G2 TT. The 1800 is very simple - a dial with clicks for 8 levels - one button for momentary - one button for continuous. (Closest TTis probably the 90.) Two dogs run on 4, one on 5, and the dial is rarely changed for a particular dog. This prevents errors. I see all the buttons and switches on the TT models as a source of error and the transmitter seems a little bulky. Some of the Dogtra models seem to have a too-small transmitter. The LCD readout of levels on the Dogtras seems almost useless to me if you're trying to change level "on the fly." (I assume there are still clicks on the TTs.)
The 1800s have been very reliable, but I have replaced the batteries (after 7 or 8 yrs). They can't last forever and the 1800 model has been discontinued, so I am curious if there are people who have used the Dogtra 3500 (or other) AND a TT model. Lots of folks on here like their TT models, a few like their Dogtras and others, but this isn't really a comparison.
Quality-wise Dogtra and TT seem comparable from what I read. I also have heard some problems with plastic guides on receivers breaking and charger troubles on some models... so comparisons of numbers of problems and customer service would be good, but single anecdotes aren't as good as a large sample. Is there such a thing? (Maybe only Collar Clinic would know... and they might not know the manufacturer fixes???) A basic collar that works is better than a fancy one that's at the shop... (and it's better to be rich and healthy than it is to be poor and sick.)
The Dogtra Edge seems to primarily be set up - control wise - to run multiple dogs. (I guess Chris does that with a TT 70.) I'm mainly interested in training one dog at a time.
I'm a Dogtra guy...they've been good to me delivering a quality product at a reasonable price and having EXCELLENT customer service over the past 6 years I've used their stuff.

Pro 100 G3, love that collar.
I like the bigger TT controller, actually the old style worked better for me. I use a vest with a pocket and velcro strip for the antenna. This is nice because I can quickly get to the controller for a correction. When hunting I already have a whistle and calls around my neck so I don't care to have anything else there. Also when hunting in late season pheasant I usually have gloves on. I have had the TT Pro 500, Upland and Flyway (the last two are basically the same) and I do have a G3 sport which I do like for yard work or taking on walks. This is my vest and they don't make them any longer.
I am not sure why more companies do not make a pocket for controllers. I have watched ebay for a few years and have bought a couple extras of these vests but now my son has claimed one and my last puppy chewed one up that my son left laying on his crate one day.
