For your consideration is this Oceanic puck 150' depth gauge in very good 9.8 preowned condition cosmetically and serviced mechanically 10.0. I would grade this item a 9.8 out of a perfect 10  because of  imperfections on the viewing lens. The gauge was cleaned, serviced, new oring installed and inspected prior to listing. If you have any questions or need more pictures please do not hesitate to write me and I shall get back asap.
