Hi all, I have not had a lot of opportunity to use my detector it was recently serviced and I just got it back. I've been having an issue when I detect at the beach after getting home and rinsing the detector off I found that a lot of sand has been accumulating between the coil plates. I do not have a coil cover, but this is a concern because if sand is getting in I can only imagine that salt water maybe getting in side the coil as well. I have had the same issue with another Minelab coil the n e l 15 inch attack coil. Just wondering if this is a common problem, I believe I saw a thread with sand getting in between the coil and coil cover. Just wondering how people are getting around this or if there is a recommended fix.
