I will look into the bounty hunter and and whites. I have also been reading about the euro tek pro. Looks like no ground balance on the euro tek but really good reviews. I am still confused on which one. I can't ever remember being back and forth so much when buying something. Seem just about all are good.
You noticed that did you! :-)
When it comes down to it, a better MD is not really going to find very much more than the one you have. You will get more options.. Multiple tones that help you know (after you dig enough stuff) what the target MIGHT be, before you dig it with just the sound.. VID which give you and idea of how conductive the target is.. i.e. on my machine a Quarter is 84+- a steel bottle cap rings up as a jump VID 80-90 with 50-60 -90 but sometimes depending on the amount of rust, length in the ground, amount of moisture etc etc can ring up a 84! It is not exact and something you must learn to interpret. Ground balancing, auto tracking, discrimination, notching, coil selection. all just options to help you dig less trash .. and last but not least the higher end units have a little more power sometimes, getting you a little more dept.. But it is more the options, speed of processor etc. Ground balancing is one thing that can be a little more important depending on the type of soil you are using it on..
Beach wet salt sand is typically a different type of machine and should be considered before you buy if that is something you plan to do.
To be honest, when I started I just went with whites as it was well documented as one of the best customer service, American Made, and it had all the nice options with a price to option list that seems good. I am happy with it. Other I know went with an F2, and of course 6 months later felt for some reason the AT Pro would find them more stuff so the Upgraded.. A lot of it has to do with hanging out on these forums and getting the feeling you are missing something when in fact the location you are hunting and the amount of time you have logged with your machine has more to do with what you find than the machine you use when talking about entry and mid level VLF (very low frequency) machines.
Hope that helps a little.. sometimes you gota just set a price, and pick the best bang for the buck!
