I recently sold my MXT and have a few accessories left over. I have a set of Sun ray pro gold headphones in great shape. I also have an SEF 10x12 butterfly coil in perfect shape, still in the original box. I did use the coil for a very short period of time on a school soccer field, grass only. The coil has had a cover since day one. i am interested in an ACE-250 for my son. The detector needs to be in as good condition as the headphones and coil.
