Some approximated densities at 20˚C/68˚F water. • Average Ocean water has approximately 1.025 kg/liter. • Mediterranean Sea has approximately 1.027 kg/liter. • Red Sea has approximately 1.029 kg/liter. • Black Sea has approximately 1.012 kg/liter.
2. If you decide to change between modes before the 48h interval or full desaturation you have to go to desaturation reset menu and make a manual desaturation reset. By pressing the SEL at this menu the mode starts blinking. By pressing right or left you may select between SCUBA, gauge or apnea modes. By pressing SEL the setting is confirmed. 1.7 SQUARE AS A DIVE COMPUTER Square is a full-featured diving computer, capable of multigas decompression calculations, ascent rate calculations and warnings.
LEFT BUTTON action backlight bookmark APNEA manual stop the dive SCUBA start the “stop watch” counter mode press Short Long Short Short Short Long Short Long 2.2 2.2.1 Altitude diving Altitude classes, altitude warning and no-fly time after a dive. Going to altitude is in a way similar to starting an ascent from a dive: you expose your body to a lower partial pressure of nitrogen and consequently you start offgassing.
2.2.2 Altitude and the decompression algorithm Atmospheric pressure is a function of altitude and of weather conditions. This is an important aspect to consider for diving, because the atmospheric pressure surrounding you has an influence on ongassing and offgassing of nitrogen. Above a certain altitude, the decompression algorithm has to change in order to account for the effect of the change in atmospheric pressure.
Decompression dives in mountain lakes In order to assure optimal decompression even at higher altitudes, the 3m/10ft decompression stage is divided into a 4m/13ft stage and a 2m/7ft stage in altitude ranges 1, 2 and 3. If atmospheric pressure is below 610mbar (altitude higher than 4000m/13300ft), no decompression calculation is carried out by Square (automatic gauge mode). In addition, the dive planner is not available in this altitude class. 2.
After a desaturation reset the NOTE: change between the modes: Gauge, Apnea and Scuba are possible immediately. However, since the gauge and apnea modes are not tracking your tissue nitrogen loading, it is recommended to keep the initial intervals between changes on modes. WARNING: Diving after having reset the desaturation is extremely dangerous and is very likely to cause serious injury or death. Do not reset the desaturation unless you have a valid reason to do so.
2.5.1 Square enables you to use up to two gas mixtures during the dive (air and Nitrox only). The two mixtures are labeled 1 and d, and must be in ascending order of oxygen content. English a maximum value of ppO2max of 1.6bar. For oxygen concentrations of 80% and higher, the ppO2max is fixed at 1.6bar and cannot be changed. The MOD for gas d is the switch depth for that gas. This is what Square uses for its calculation, warnings and suggested switch point.
if after Square has changed NOTE: the decompression schedule to reflect the missed gas switch, you descend again below the MOD for gas d, Square reintroduces gas d into the calculations and the decompression schedule changes accordingly. 2.5.1.4 2.5.1.2 Switching back to a gas mixture with lower oxygen concentration There may be situations in which you have to switch back to gas 1 from gas d.
WARNING: 2.6.1 English represent situations that require the diver’s attention, but ignoring them does not represent an immediate risk. It is up to you to decide which ones you would like to be active and which ones not. The available warnings are: CNS O2 = 75% Square tracks your oxygen uptake via the CNS O2 clock. If the calculated value of CNS O2 reaches 75%, Square will emit a sequence of audible beeps for 12 seconds and the value of the CNS O2 will be blinking in the lower right corner.
Square emits a sequence of audible beeps and the DECO STOP symbol blinks, both for 12 seconds, when the L0 no-stop time ends while diving with an active MB level higher than L0. 2.6.5 L0 no stop time = 2 minutes when diving an MB level When diving with an MB level higher than L0, the underlying L0 information is not directly visible on the display (though it is accessible as alternate information).
DEPTH ASC SPEED m ft m/min ft/min 0 0 7 23 6 20 8 26 12 40 9 29 18 60 10 33 23 75 11 36 27 88 13 43 31 101 15 49 35 115 17 56 39 128 18 59 44 144 19 62 50 164 20 66 If the ascent rate is greater than 110% of the ideal value the SLOW symbol appears. For ascent rates higher than 140%, the SLOW symbol starts to blink. WARNING: The ideal ascent rate must not be exceeded at any time since this could lead to microbubbles in the arterial circulation which could cause serious injury or death. English between 7..
The audible signal is repeated for 5 seconds in one minute intervals after the first occurrence and for as long as the value of CNS O2 stays at or above 100% or until the ppO2 drops under 0.5bar (see chapter Diving with nitrox or with another decompression gas for a list of depths at which ppO2 equals 0.5bar for some typical Nitrox mixes). 2.6.11 2.6.10 During the dive, Square alerts you of precarious battery situation by displaying a steady battery symbol on the screen.
English Depth: the depth is given in 10cm resolution when metric mode. When the depth is displayed in feet, the resolution is always 1 foot. At a depth shallower than 0.8m/3ft, the display shows --. Maximum possible depth is 120m/394ft. No-stop time: calculated in real time and updated every 4 seconds. Maximum displayed no-stop times is 99 minutes. WARNING: During all dives, perform a safety stop between 3 and 5 meters/10 and 15 feet for 3 to 5 minutes, even if no decompression stop is required.
2.7.3 Safety stop timer If a minimum depth of 10m/30ft has been reached during the dive, at a depth of 5m/15ft the safety stop timer will start according to settings either automatically or you may start this by pressing a button. If you go below 6.5m/20ft, the timer will disappear and the no-stop time is shown again. Upon returning to 5m/15ft, the timer will start again if set to automatic. As long as you are shallower than 6.
L0 information in background 2.7.7 No-stop No-stop Display shows L3 no-stop time. Level stop No-stop Display shows L3 level stop information. The white STOP symbol appears on the display. Level stop Decompression Display shows L3 level stop information. In addition to the white STOP symbol, also the black DECO symbol appears to indicate that also L0 is in decompression.
Once PDIS depth has been reached, you should stay on the zone that is -0.5m..+3.0m / -2ft..+10ft from the shown PDIS depth. If you descend below this zone the PDIS counter will be deactivated and Square calculates a new PDIS depth. WARNING: Dives in gauge mode are performed at your own risk. After a dive in gauge mode you must wait at least 48 hours before diving using a decompression computer.
As in SCUBA mode, press right to view the time of day for 5 seconds in the bottom row left and other alternative information at the bottom row. In the display below the time of the day has been selected (23:43) combined with average depth (12.8m). data is saved in 1 second intervals. The higher amount of saved data requires more space and the consequence is that approx 10 hours of log data can be stored in Apnea mode. English While in gauge mode, the average depth can be reset.
3. SQUARE ACCESSORIES 3.1 HR belt Square receives the signal of the various low frequency heart rate belts, for example Polar or Scubapro belts. The position to wear a HR belt is shown below. Alternative information can be selected by pressing right button. The information can be scrolled in following order: 1. Sequential dive number Adjust the strap so that it is comfortable to wear but so that it holds on the place. When using a diving suit the HR belt must be directly against the skin.
SQUARE PC INTERFACE 4.1 Shark English 4. The communication between Square and PC/Mac is possible only with a Shark. 4.
