Took a road trip to Tesoro the other day. Met up with Rusty and bought a new 5.75 concentric coil for my new lobo s t. While waiting for Carl to do his magic balancing job on my new coil, my wife and I went over to Rusty's house to visit. My wife really fell in love with the lobo s t. We ended up going home with another lobo s t. Now my wife is bugging me for a 5.75 concentric coil for her new lobo. I guess we will be making another road trip to Tesoro next month. I tried it out on a small piece of gold I have and it really works. Very sensitive coil. I have owned a lot of detectors in my life, but Tesoro is hard to beat. There is no company that beats their friendly service. Ya gotta love em'. I really enjoyed dealing with Rusty. He reminded me of the old days when you went in to buy a product the salesperson knew the product well, took the time to listen to you and then interact and sell you the right detector. Rusty is the nicest person we have ever met. A great guy and a real asset to the Tesoro company. Keep up the good work folks.
