lost wrist computer, smb, reel, and bag of conch shells in jupiter

I was out sunday and a guy lost his computer while on his safety stop. He had 2 large conch shells in his bag so he tied the bag to his reel and smb and let them go to mark where his computer went down. unfortunately, the smb never made it to the surface. we were diving near the area 51. there was also a brand new anchor and chain very close to where this took place. if anyone stumbles on any of the gear, please let me know and I can put you in touch with the owner.
thanks.
