I used this once outdoors, but I've been using the main unit indoors, so I'm selling it since I haven't had a chance to use it. There's a small scratch on the clasp (see photo 2), so I've marked it as "slightly scratched," but otherwise, it's in good condition. This is an accessory specifically for MATT. It has a ring that snaps on easily and a shoulder belt that can be adjusted with a buckle. Please understand that this item has been stored at home. If you have any questions, I can upload additional photos, so please feel free to contact me.
