| Only reason I will be going with the MXT Pro instead of MXT is its only a 50 dollar difference for a few more bells and whistles. | |

The sad fact is that your difference in price may hide a vastly different level of usefulness. Some of the things that different manufacturers do is not related to the knobs, bells and whistles alone. They are related to things you simply cannot see with your eyes alone or by reading answers here from devoted users of one brand or another. This is a problem for most beginners just starting out. Some of the invisible yet crucial attributes are:
1. Field Strength of the TX field.
2. RX sensitivity and noise rejection.
3. Field pattern(s) of the machine.
4. Pulse width of the TX blanking time (in PI machines).
5. Type of discrimination.
6. Ground balance veracity (this is important - read more below).
7. Cable integrity between coil and control box.
8. Warranty.
The veracity (truth and accuracy) of ground balancing is an opinion in the engineering community - not an exact science. If you absolutely know the soil below your coil, you can design a circuit that will make it transparent down to the depth capability of the detector. That much is fact, rather than opinion. Since there are a bazilliion soild types in this world, there cannot ever be a perfect match on ground balance. Ever. This is also a fact. Thus, the claim of an accurate or truthful ground balancing are carefully worded to indicate that their circuit can take care of most, not all, soil conditions. Leaves them an out and tells the truth. This is why the newer PI machines are so popular these days. There's not need for ground balancing at all because they do not respond to mineralization.
I hope you are beginning to understand the complexity of making a choice. .You already have caution in mind by asking but to expect an answer is just so illogical. Your choice is going to be based on some physical attributes like weight, size and ease of control box use. Some of those things are important and some are simply just not worthy of concern. The invisible attributes are far more important and for those, you need to read the technical literature provided by the manufacturer. I have, in my experience, found that all traditional metal detector manufacturers of the major brands to be truthful in their advertising. Even on ground balance. If you have serious questions, you can actually look up patents held by those companies and used in their machines. Then you can read the actual theory, if you are so inclined, of their operation in detail.
Once again I will advise you to look into yourself and determing what your targets are going to be. The detector that is perfect for you to find rings, coins and jewelry will not be suitable for finding a chest full of gold. Just last week I found this absolutely enormous signal target that went the length of a stone foundation. I was very excited and started digging. I found a 12 foot pipe that had been cast there probably during demolition of the ice house which once stood there. Such is life.

It's all about that moment when metal that hasn't seen the light of day for generations frees itself from the soil and presents itself to me.
