| | Mares Ruby Scuba Diving Regulator (Site not responding. Last check: 2007-10-13) |
 | | The seat connector, manufactured with a special high-tenacity technopolymer, translates into water-tightness; its life cycle is much longer than that of traditional valves and doesn't require special maintenance. |
 | | Upgrades of the most advanced MARES second stage include: the front shield in stainless steel protects the regulator, whereas the wide thick-mesh grid breaks the water flow and prevents free flowing of air even when swimming in strong currents. |
 | | Its exclusive design, featuring eight profile screws anchoring the shield to the special technopolymer cap, highlights Ruby's exquisite design and performance characteristics. |
