I have a Whites MXT 300 , I have had it forabout 4 or 5 years now. I dont get the time to use it much but I do enjoy it when I do. Mostly find junk but every now and then I might find a newer silver piece . The most valbule thing I have found was actually on my own property , I located a 2" brass pipe that ran about 160' to a large water cistern about 6' by 20' and 8' deep all brass .
I find haveing the decter makes me a local history buff , Always trying to find the forgoten stuff, I live in a area that has ben populated for a LONG time for the US so theirs alot
My faviorite spot is a former army base pre civil war to around WWII, lots of gems for the millitary buffs
In my state they charge a 40$ fee for a yearly permit to dig in/on state land , it was only 10$ 2 years ago
