Knobs and switches man!!! That's what it's about!! I just can't get on board wit this new tech. These kids today with there smart phones and screens and minus. I can see the day when a detector will be just like a smart phone. You just buy an app for any model machine the company offers and download it to your detector. You could have multi machines on one unit. Me I will just show up with my old school Tesoro with the knobs and switches and be a novelty to them. They will think I just stepped out of the 70's. Heck I may even grow my sideburns out and buy some polyester to wear when I go tectin. Some big o'l chrome cop sun glasses and a trucker hat....yeah that's the ticket.
