the sunray in-line probe is much superior to free-standing pinpointers, IMHO. The best parts about having the inline probe, is that a) the sound comes in through your same headphones, and b) it's operating off the exact same settings (tone ID's, disc settings, etc....) as your detector settings. After using one for awhile, you'll feel very naked NOT having one on a machine. A lot of fun, and they keep your holes much smaller.
