Mares Genius Dive 495125 Water Sports | sku-923272351

The Mares Genius wrist dive computer, model 495125, is listed under Water Sports with an LED tank transmitter. UPC: 792460380586. SKU: sku-923272351. Its color TFT display has a mineral-glass lens and measures 2.7" (68.6mm) diagonally. The computer uses the ZH-L16C algorithm with gradient factors and predictive multi-gas functions. It supports Air, Nitrox and Trimix, with up to 5 gases. The tilting digital compass works up to 80 Degree and has bearing memory and a stopwatch. The display has adjustable backlight brightness and a night mode. The included hose-less LED transmitter sends cylinder-pressure data to the computer by coded RF after the two are paired. The computer displays pressure and calculates gas consumption and time remaining before reserve. It can monitor up to five transmitters when optional transmitters are added. The stated pressure display reaches 4,350 psi (300 bar); the specification list also states up to4350 psi (300 bars). The transmitter specification gives a maximum pressure display of 0 to 5000 psi (0 to 350 bars). It attaches to a 7/16" threaded HP port on the first-stage regulator and uses a user-replaceable CR123 battery. An optional transmitter is also referenced as SKU: MRSQT. Altitude adjustment reaches approximately 12,100' (3,700m), and the depth display reaches 492' (150m). A quartz movement keeps time, date and dive time; the display also shows temperature. Clock settings include 12/24-hour format, time, date, time-zone shift and wake-up alarm; the specifications also list dual time and a daily alarm. Bottom-timer mode has resettable average depth and stopwatch functions. The decompression planner includes an additional surface-interval function. The logbook stores more than 1,000 hours of dive profiles at a 5-second sampling rate and provides multiple graphs. The rechargeable lithium-ion battery provides 40 hours of dive time per full charge and has a charge indicator. Bluetooth connects the computer directly to a smartphone. During a dive, it can show maps and a detailed tissue-saturation graph, and its underwater menu allows certain settings to be changed. It has future-decompression and proprietary runaway-decompression alarms, plus audio and visual alarms. The computer is upgradable and can display imperial or metric units for fresh or salt water. The transmitter's LED shows tank status at the surface without the computer and signals pressure thresholds during a dive. It turns on at 145 psi (10 bar) and turns off below 145 psi (10 bar). It also turns off if pressure stays unchanged for more than 4 minutes, then turns on again after a change greater than 14.5 psi (1 bar). At 2600 psi (180 bar) or more, it initially blinks Green 10 times at 4-second intervals; the 2600 psi (180 bar) threshold can be set through an Android app. The listed warning colors are Green at 2600 psi (180 bar) or more, Yellow at 1450 psi (100 bar), and Red at 725 psi (50 bar). Green and Yellow blink at 4-second intervals; at 725 psi (50 bar), Red blinks once every second.
