I received the headphones they increased the sounds about 4 times.
Now I can pick up the signal of a gold nugget the size of a wheat grain at 8 inches where with Minelab standard was 3 inch.
I have a hearing loss of 75 percent both ears.
My nephew was able pick up sound at 12 inch’s.
I am thinking I may buy a Garrett 2500 with Eagle eye from you but still checking them out.
I would like a deep seeker to find caves and tunnels but limere on money.
