I've made about 5 trips to Florida over the past few months and I've found 15 gold rings in that short time. The last trip yielded 6 gold rings with the last one being a 1/3ct heart shaped diamond. This area of water has probably never been detected before. Add the fact that my Excalibur 1000 is still running flawlessly after five years and I feel like I'm unstoppable. With all of the nicks, bumps, and stickers fading and starting to bubble it's not much to look at but man will that thing find gold. I just run it with discrimination turned all the way down and the sensitivity at about 12 o'clock and it's almost a cake walk from there. I guess a little research and finding the low areas in the water didn't hurt either. With as many good things as I've heard about the Excalibur II series I'm just too attached to the one that I have now to upgrade. Keep up the good work. Rick Poole - USA
