SCA-251 - TUSA Element
The SCA-251 two gauge Element console features the IQ-650 Element dive computer and a 4000 PSI pressure gauge in a compact low-profile two color boot. The computer console is a full-featured, user-friendly instrument with an innovative interface designed exclusively for divers.
The 4000 PSI pressure gauge features a helical bourdon tube for a more accurate display of remaining air. This gauge features TUSA’s Lumi-Nova luminous face. Easier to read and several times the brightness of standard luminous gauges with longer luminescence times.
The Element is an easy-to-use, single button, puck-style computer offering a myriad of dive data details plus some new features including a Deep Stop function all in an affordable package.
Deep Stop Function
Several TUSA computers feature a deep stop function for additional safety. The deep stop mode is activated when a dive exceeds 80 FT (24M) for more than 1 second. Upon ascent, the computer will display a Deep Safety Stop screen and the recommended stop depth for a period of 2 minutes. This deep stop is highly recommended as additional opportunity to off-gas, but is not mandatory. If the diver chooses not to serve the stop it will not adversely affect the remaining No-Decompression Limits of the dive.
