I have a bunch of extra scuba diving gear that is just setting around gathering dust. I have upgraded and no longer use it. Some is new but most is not. I have fins, masks, 3 extra bc’s (vests) booties and I don’t know what all…contact me and let me know what you need and I will see if I got it. I do not have extra tanks or regulators but I do have most everything else. As you know, you should never just jump in the water with gear that has not been checked out first but it was all working when I upgraded and quit using it. Let me know what you need. Use contact seller to let me know so I can look for it and get back to you
