First off, welcome aboard.
I am in no way a detector know it all, but am currently looking to upgrade from a beginners detector. I looked at the Land Ranger Pro and it certainly has all the desireded features. ( DVI, Pinpoint and such ) Before spending the money, I'd suggest researching depth comparisons on youtube as mentioned below. Not that I think it won't be a deep machine,, I simply don't know. Just making the suggestion that you insure whatever machine you buy will get you decent depth. I can tell you that the Bounty Hunter Platinum was not especially deep in my area/soil. Another machine I was kinda interested in is the Fisher F5. They seem to have a very positive reputation. I hope you have better luck coming to a decision than I am,,, there are just so many options.
