Identifying in ground before digging; Canadian clad is a challenge for sure but the Manticore is much better with it than the CTX IMO. One thing to remember is Canadian clad from 1968 to year 2000 has high nickel content. After 2000 they all became steel coins is my understanding. That high nickel can affect how they ring up on a detector. I just got my Manticore and have had good experiences finding Canadian steel clad with ferrous upper limit opened around the 61 VDI, on the 2D I usually get a visual horizontal line there and then a diagonal line from that down to the lower left. Sort of like a hockey stick (I kid you not). Recovery speed set to 3 or 4. This is mostly NOT the $1 Loonie and $2 Toonie coins though, just steel quarters, dimes and nickels ... still need to dig more dollar coins in the dirt to make a generalized statement. PS what ever happen to "dig it all"
