I've got the old t20 , with a doubler on so I suppose it's the equivalent to a t50
I've inserted the new AS pill , and is good to 250 yards easy
I've just bought the EVO 75 ,with same pill but not had it out yet , there supposed to be the dogs dangles , out to 500 yards
If your only going to 100 yards them a t38/50 will do you proud ,
I just like to see further a field so to speak
One more thing mate are you using a ajustable mount with the torch ?
