I was just looking at a friends post showing his CTX 3030 finds and thought I would share this. If you want to save the value of your investment here is what I purchased from Gerry McMullen to keep my 3030 in pristine condition. It comes with a WM protector and a display cover included. It is for the GPZ 7000 and it just a little big on the battery end but works just fine. Get a hold of https://gerrysdetectors.com/ to get yours.
