After having the Treasure Pro out a couple of times, I would compare it more to the 6T than the MX5. It is a nice detector (love the display) and easy to operate but from my experiences with it, I wouldn't call it a depth monster but has adequate depth for most situations. I also want to stress that I don't look at the depth of the machine by it just making a tone but it must have a correct VDI before I count it. Like most detectors the TP will give you a tone of some kind before it gives you get the numerical display. I am going to do some more testing because in my short test, it seemed to ID by catagory (quarter, dime, nickel etc.) correctly before you get the number. It is pretty stable and the only coil that I have used on it is the stock D2. Most of the places I hunt regularly are pretty trashy so the D2 is too big for my taste. I have used other machines with the D2 and have had the same opinion of the coil on those detectors too. I have ordered a NEL Sharpshooter for it and it will be here this weekend. If I can get 6 inches on a dime with the small coil, I will be pleased and will use the Treasure Pro in modern parks and tot lots. When I want to go deep then the MX5 will definitely come out. I am hoping to get a Ultimate 13 for it when I can. The Treasure Pro is a fun little machine and it will hopefully be good for what I bought it for. I think for the price of the machine with the features and performance it gives, it's a good deal especially if you just want a detector to keep in the vehicle for quick hunts or scouting out potential sites. I think that it is crazy to try to compare a $350 detector against detectors that cost 2 or 3 times that so with that being said, I like the Treasure Pro and it performs adequately and has some really nice features.
