I have a Fisher F75 with a SunRay probe, don't use it much, the shaft cam could be replaced. I am looking for a Garrett AT Pro. I have been on this forum for years and sold thing on here. I don't post much, I do read on here. The F75 is one of the first ones out, it was sent back to Fisher for an upgrade, Mike Scott was the one that I talked with at Fisher, I picked up my CZ3D from him. The SunRay probe is also one of the first ones. I use my 3D more then the F75, thank you for looking if you pm me I will give you my number, I live in the Peoria IL area
