I have never used a Troy, but our md club has one guy that seems to have at least one of everything (don't know that for a fact, but he does own many different detectors). This guy doesn't buy them - he is just unbelieveably lucky and enters detecting contests all the time - and more often than not walks away with the top prize - or at least another detector - and he's been doing it for a long time. At least one in his stable is a Troy. (I don't know if it's an X2 or what) but, anyway, he likes it. I see him using the troy pretty often for parks and schools. He won't part with his PI PRO for the beach, and I see him occasionally using one of this other detectors - Garrett, Fisher, Whites, Minelab, Tesoro... but, like I said, the Troy is probably his 2rd choice after his DFX ...He says its a simple but very fast detector - much like the Tesoro....and he likes to use it for competition hunts.
I also know the Troy people are very good about supporting the hobby. They have donated "kiddy" detectors several times for our club fundraisers. (Great little detectors for the 5-9 year old bunch).
