Cressi Neon Wrist Computer

The Neon is an intuitive, reliable dive computer with a fancy style. It will become easily your best friend for any scuba diving or freediving session. It has the dimension of the watch, will accompany you in every moment of your journey, adventure.
It is the seventh project designed, developed, and produced in Italy by the Cressi subsidiary Cressi Elettronica. It is an elegant and polyvalent proposal, under its sporty aspect and attractive watch hides a complete dive computer and apnea that stands out for its versatility. Suitable for the advanced diver or for technical diving and for apnea or snorkeling, but surprisingly simple for the average diver by providing information clearly and simply with just two buttons. It has a diameter of only 48 mm and a high contrast display of 37 mm.
Intuitive new menu navigation system and parameter input for maximum usability. The ease of configuration, navigation through the different menus, and access to a large amount of information are always very intuitive. You can choose between four modes: Air, Nitrox (EAN), Gauge, and Free for maximum versatility. The computer uses the Cressi RGBM Wienke 9 tissue algorithm for diving safety. The safety factor is customizable, from conservative to more conservative. It is possible to set multiple dives with different gasses. Possibility of using two different mixtures in the same immersion, 1st mix from 21% to 50%, 2nd mix from 21% to 99% O2 with 1% increments. Ascent speed with graphic indicator and visual and acoustic alarms. Acoustic, visual, and screen illuminated alarms: PO2, CNS, ascent rate, DECO, DECO skipped, maximum depth exceeded (optional). Optional safety stop ("Stop") in case of dives in the safety curve. Indication of no-fly time and desaturation time. High-intensity backlight function (4000 Mlux, more than twice the number of computers with the highest illumination power to date). Temperature, time, instant PO2, maximum depth allowed, and mix used visible underwater at the press of a button. User-replaceable battery. Approximate autonomy of 4 years (50 dives per year). Logbook: 50 dives per modality or 40 hours.Reset option via the menu. Eliminates residual nitrogen memory for use in dive centers for rental or teaching. The dive computer can be linked to a smartphone using the BT Interface (sold separately). It communicates with the dive computer via an IR connection. Use the Cressi app (available for Android and iOS) to download diving sessions and monitor training. The device is powered by a long-lasting CR2450 button battery which can be replaced by an authorized Cressi center by verifying perfect watertightness.

CONSTRUCTION

• Anti-impact technopolymer case. This composition allows great lightness, resistance to the blows, and aesthetic aging. The computer case is extremely flat, with a very hydrodynamic cornerless section and its dimensions are relatively contained, with a vision of the model digits.
• Extra-flat profile (maximum height 14 mm) with a completely rounded design, very hydrodynamic, and avoids possible snagging. Even the anchorage of the strap follows the profile of the box.
• Two highly integrated low-profile pushbuttons with a minimized backlash to ensure that the O-rings are watertight when working perfectly perpendicularly and to prevent the entry of particles or small grains of sand that could block them.
• Case diameter is only 48 mm | 1 7/8 in.
• Large screen UFDS (User-Friendly Display System) 38 mm in diameter vs 48 mm total box. The distribution of the information, screen contrast, proportions, and size of the digits have been studied to facilitate the reading. All data are segmented with slight separation lines that facilitate reading even in a stressful or emergency situation.
• New high-performance, low-power processor. It allows much faster data processing, more power backlighting, and sound alarms and doubles the battery life compared to previous models. CPU ARM Cortex M3 32 bit | Frequency14 MHz | Flash Memory 256 Kb | 32 Kb RAM.
• High-intensity backlit display by push-button or in case of alarm (5 seconds per push)
• High-strength mineral crystal display.
• Guaranteed resistance up to 120 m | 394 ft depth.
• Optional Bluetooth interface.
• Thermoplastic rubber strap with stainless steel buckle.
