Cressi Neon Dive Computer

After the successful Leonardo, Giotto, Newton, Drake, Goa, and Cartesio, NEON is the seventh project designed, developed and produced in Italy 100% by its subsidiary Cressi Elettronica.
NEON has a diameter of only 48 mm and a high contrast display of 37 mm.

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.

CONSTRUCTION

• Anti-impact technopolymer case. This composition allows a great lightness, resistance to the blows and to the 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 only 48 mm
• 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)
• Mineral crystal display
• Guaranteed resistance up to 120 m depth
• Optional Bluetooth interface
• Thermoplastic rubber strap with stainless steel buckle
