HI
i am a high end detector user
i bought the ace 250 for a back for me and my girlfreind to go out togehter and detect (here 3rd time out maybe 3 hours of use she pegged a 1919 s wheat at 6 inchs she spanked me taht day with the oldest find

)
i was working a site that i have been digging for about 3 weeks (about 7 days total on weekends mostly)
i figured one day that id bring the ace along just for gigles to see what this little bad boy can do
first impression it was very talky as i had not notched anything but iron out
but with the presets and notching i notched out all sept coins
so i was swithing between machines running into iron nail piles
they would ring in as a coin for a moment then peg into the iron foil range
so just to be sure i was not hearing masked tones
i would pull up the other machine dig the hole and yep is iron hallow effect
usually most all the times it did this it was pegging at a depth of 8 lots of nail is this depth range
well as i made my way threw the area to rest the machine(ace )against a tree
i got a GOOD solid coin signal it was bouncing all over the coins id range but not into trash at all!!!
prolly a wheat penny i tell my self so i dig a 3 inch hole and hit a root at 2 inchs
still in the hole this time its pegging in the silver range
as i dig around the hole out poped this
it was at an 45 ' angle just below off the the side of the root was a shocker to say the least
2nd oldest coin i dug there so far (1883 v nickel with my troy X5 at 7 inchs)
