purchased the sdc and went out yesterday to try the detector out and tried to use the headphones supplied with it. The headphones keept slipping of my head when digging targets, so i put my beanie over the top, this worked but soon after it was just to hot to wear. I can get away with no headphones at present but the cicadas will be out soon. Has anyone a mod to keep them on my noggin. Or should i just buy a hard wired or wireless set of headphones.
