Just wondering if anyone can help me? I'm looking to purchase a new terrier locator, as I've had enough of the Deban terrier finder(with the disco lights and sounds!). The people I know in the terrier world all rave about bellman and flint, you could say its considered the rolls Royce of locators! But someone mentioned ortovox locators(D3 to be precise), I've tried to research this and all I can find info on is the reciever boxes. Do they produce collars? Or a transmitter that you attach to a collar? Or does anyone own one that they can tell how good they are? I would buy a bellman and flint,
