Hello Deese
The Sovereign GT is a great machine for the beach. It is considered by many experienced beach hunters to be one of the best for salt beaches. It does have a steep learning curve, but once you learn what it's telling you, you'll love it. The beaches I hunt have a lot of iron junk, and the ability of the GT to null this out makes it the machine of choice for me. As far as it's ability to disc and notch out junk and pull tabs, the GT does this well. But you have to keep in mind the "good" stuff you want to find falls in the same range as junk. To disc pull tabs means you may be passing over gold rings. Digging on the beach is easy, so I dig it all except the iron null. Even with the iron nulls I listen close to make sure there's nothing good next to it. Here is a VDI chart to show the numbers on a VDI meter to give you an idea of what you can miss by not digging what you think is a pull tab.

I own a Sovereign GT and love it. I upgraded from a White's M6. The salt beaches that I hunt on drove the M6 crazy. Lurking on metal detecting forums I quickly learned that many of the more successful beach hunters were using the Minelab Sov GT or for in the water, an Excalibur. For me the Sovereign was a good choice. If you just want a turn on and go machine you might want to go with something else. JMHO
