I have checked into this and am scratchin my head, wondering what the big deal is. First, LC has them, or will in a week. http://www.gundogsupply.com/tri-tronics-g2-exp.html
This "up to 6 collars" thing has me thinking hype though. And I am a TT fan.
I talked to the people at Cabela's this past weekend. As they understand it, or as I understand it from them, a standard transmitter will be able to operate only one collar at a time
. It is true that you can add up to six collars. The transmitter and receiver do this by exchanging coding info. with each other. But unless you have the version that allows toggling between collars, you can only operate only collar at a time.
So here is how the multi-collar thing works, I am told. You have six dogs. You buy six collars, and put one on each dog. You work one dog. You bring it back to the truck and take out another dog with a different collar. The transmitter and collar will "talk" to each other, figure the coding thing out, and you can then run that second dog using the collar. And so forth through all six dogs. But you could not take dog 1 and dog 2 out at the same time and be able to switch from one collar to another out in the field with the transmitter. So only one of those two dogs actually has a live collar on, one that you can transmit to from that transmitter.
There is the Pro G2 EXP. That allows up to three dogs to be run at one time. You can toggle between the three from the transmitter. You can actually own six collars, and the G2 EXP will "code" with any three of them, so you can run three dogs at one time. But you are not gonna be able to run six at once.
So why not, when you take dog 1 out of the truck, run it, and bring it back, just TAKE THE COLLAR OFF THE DOG AND PUT IT ON THE NEXT ONE. Sure alot cheaper than buying separate collars for each dog, but only being able to operate one at a time.
That is how it has been explained to me.
