“Thanks guys I agree, I to feel the more machines you can learn the better off a person is , but to me there no point in keeping a machine that's only good for one field when you have a machine that will cover many fields just as well,Hell I may just decide to keep em both their both paid for.”
Everyone has an opinion Tank and mine is that it won’t hurt you to hang on to both units. Where the gold is small or the mineralization is not too steep the GB2 is just an excellent unit. Even in my fairly harsh ground it is superb on low conductives, really excels on the small stuff. Your MXT will do better on slightly and larger low conductives and will better handle tougher ground minerals. Features such as SAT and ground tracking offer you versatility when searching over tough / variable conditions.
Keep contingencies in mind too. What happens if you are out searching a remote area and for several possible reasons either unit malfunctions. It sure is nice to have a back-up unit available. These units complement one another very nicely, and you can see that I own both for that very reason. That’s aside from MXT’s versatility with other metal detecting pursuits, for example…coins and relics.
On the subject raised just above about using the GB2 for coin hunting I thought I would throw the following excerpt in just for the heck of it…by the chief designer Dave Johnson of First Texas….
“The GB2 is an excellent gold prospecting machine, designed for that one purpose only without the slightest consideration for someone who might decide to use it for some other purpose. In the end however it is a metal detector and will detect metal objects other than gold nuggets. Sort of.
When it comes to general in-the-park-coin-beeping, the GB2 really sucks. I say this not as an undercover Minelab hack, but as the guy who designed the thing in the first place. Almost any good coin beeper on the market, almost regardless of how inexpensive, is going to be better for coin beeping that a GB2. The GB2 is a gold machine, designed to find the smallest nuggets, after all these years there is almost nobody who says that something else does that particular thing better, the results speak for themselves, last year was the GB2's best sales year in history. I hope nobody is buying them for beeping in the park because almost everything we sell at any price will do a better job at park coin beeping than will the GB2.----Dave J.”

Jus' like women--one mans pain 
is yet anothers pleasure 
GB Pro is definately cutting a wide swath BUT numerous models and variation screwups at inception have blackened the name 
but buds absolutely luv'm bigtime. Places they've pounded for years with ALL others minelab through tesoro have taken a back seat 
go get ya' some---John
- well the bug will be less bulk and weight
