I just purchased a Deus2 WS6 Master with the 9 inch coil. It came in the mail yesterday with an 11 inch coil in the box. Before calling the dealer and asking for an exchange, I thought I would ask you Deus 2 users/experts for some help. Last night I did a little youtube research and what I found was very surprising. In those youtube videos it showed the 11 inch coil unmasking targets better than the 9 inch coil. I will be using the Deus in trashy parks and like everyone, I want the coil that will give me the best chance to locate coins hidden in the trash. I loved swinging the 9 inch coil on the ORX that I used to own. It was light and well balanced. I'm willing to give that comfort up a little if the 11 inch coil separates and unmasks targets better. I know youtube videos and real world detecting are different animals so I would greatly appreciate your opinions on the 9 vs 11 inch coil?
