LJ, I own a ctx3030 but i haven't used it for about six months now. Mate there is a few guys on here that use them in the coin and relic section. Its a great beach detector and you will enjoy using it, plenty of hi traffic beaches down your way mate. If i was down your way i wouldn't hesitate to go out on the beach hunting with yah. LJ, There is some great info on the minelab treasure site and heaps on you tube as well. There is a good book called "Gold beneath the waves" I recommend you to read this book, good luck.
