Same as you but I also have the small puck. They offer a larger coil, but I can only get out a few hours a month, so I really don't need it. But I would love to own one.
Really hits hard on some small gold nuggets. Nice relic hunter also. It was sent to me to field test prior to the final release. Not waterproof (neither am I) but it has all three coils. Nice.
The raffle was not suppose to happen. Prizes were suppose to be given to the top point getters(based on type of find) but the Organizer took money per raffle ticket and if you won you got the prize. Definetly not cool.
My TDI Prototype. Having worked on the TDI Project with Whites, we wanted a ground balancing pulse to hunt the iron dirt in Culpeper Virginia. It did compete with the other Pulse detectors at the time which were the Minelab Gp 3000/3500 and the Garrett Infinium.
