Absolutely totally and completely correct! This is “a ways into the hobby” type stuff where you aren’t going after obvious 2 way hits anymore....you’re trying to make sites that have been hunted hard by others to produce,and you do that by progressing in the hobby. It is an absolute FACT that once signals start getting out of “obvious range” that they can indeed hit from one direction nicely and not make a sound at 90 degrees. More often than not it is the coin sitting at a weird angle OR you get an indication of a lower conductor or iron at the 90 degree sweep because it’s partially masked. I have gotten very deep coin signals at no more than 20 degrees(out of 360 total,10 one side,10 at 180!) and they indeed turned out to be coins. Not ALL of them,but enough to really wake me up. How did I know? LOOKING at the numeric indication on the CTX,and this is why,if you don’t want to take a chance on everything,that this machine shines.
This response is not to discount anyone else’s experience or criticize advice...quite the opposite. If you KNOW that these things can happen,you are more apt to go try it on some really “one way” signals for yourself. Biggest factors are...it HAS to repeat(even at that one angle) a great deal of the time,and the signal CANNOT APPEAR TO BE MOVING AROUND! Look at that one blade of grass,that one flower...your potential coin signal CANNOT deviate from that one spot.
Excellent Groper...
