Yes the digital readout is pretty small. I always try to keep my coil about an inch off the ground, I noticed that in their video also.I had to go back and check Garretts brochure, they list the 6.5"x9" coil as a DD. I think they made a typo, their only concentric listed in it is a 9"x12". What are your thoughts on the 5"x8" DD for open areas like ball fields or dry sandy areas or do you think the concentric would be a better performer there?
