Delete checklist from history
Slide the selected item in the "Assemblies" list to the left. A trash can icon will appear, click on it and then confirm.

Planner

It allows you to plan any dive, including the most challenging technical or rebreather dives.
Please note: The dive planner is intended for use by trained and qualified divers only. Decompression calculations are determined by publicly available decompression algorithms, but even following them exactly will not guarantee the absence of decompression sickness or other ascent-related accidents. Even if all decompression procedures are followed, a life-threatening situation, injury or death may occur.
Note: Before using the scheduler itself, pay close attention to the scheduler settings in the Setting gadget. In particular, it is advisable to create your used cylinder inventory for the open circuit. Of course, it is possible to change the settings later during the actual dive planning.

Opening the planner - List of plans

When you open the mini-application of the planner, a list of already scheduled dives will be displayed. Saving individual plans is useful if you dive in the same or similar locations and the already created plans will become universal helpers during your underwater wanderings.

Creating a new plan

  • Tap the red + button on the top right
  • Name the plan
  • Specify with a checkbox whether the plan is with a rebreather (CCR) or a conventional SCUBA (OC)
  • Determine the maximum depth and time at the bottom
  • Enter the altitude at which the dive will take place
  • Note: Altitude can significantly affect the decompression procedure. Do not neglect this setting when diving in mountain lakes.
  • Select the gases from the store that you will use during the dive. Oxygen and diluent can be edited at this time. Other gases cannot be edited at this time. This is possible in the Cylinders setting in the Settings widget or directly during the plan.
  • Press the red Start planning button

Planner interface

Mode

in the case of CCR planning, the first line is dedicated to switching the mode between CCR and Bailout plan. Both plans are calculated simultaneously and can be switched and compared freely. In OC mode this line is missing.

Graphical display of gas consumption:

The consumption of all selected gases is graphically displayed above the dive profile itself. The slanted curve symbolizes the gas loss in a given dive phase. The colour coding symbolises the type of gas and the sufficiency or insufficiency of the gas.
White = air
Green = Nitrox
Brown = Trimix
Blue = Oxygen
Yellow = Gas supply is below the specified minimum level at the end of use
Red = Insufficient gas for scheduled dive

Settings

Extensive application, scheduler, analyzer and user profile settings.

The settings are divided into four basic sections, which are listed on the bottom line of the screen: Planner, Cylinders, Analyzer, User

Note: before setting the values for the first time, you can change the metric/imperial units in the User settings to the ones you want.

Planner settings

Select the type of dive you will be shooting for CCR = Rebreather, OC = Open Circuit

CCR settings

SP Descent - PO2 setpoint to be used during descent in the planner. Note that this is not the variable descent setpoint known from the CCR Liberty setup, but a fixed setpoint for the entire descent until maximum depth is reached.
SP bottom - setpoint used in the deep part of the dive
SP deco - setpoint used for ascent. It starts at the exit start point.

OC settings and common settings

The following items are common to both CCR and OC.

SAC stress - Surface consumption on the open circuit for the duration of the emergency. Consumption is recalculated for ambient pressure. Set high consumption for realistic planning when a critical underwater problem is being addressed at the worst possible moment. In the case of a CO2 hit, consumption can rise well over 75 l/min. The SAC stress value is calculated into the plan for the time specified in the Stress time item.

SAC Deco - Surface consumption on open circuit after Stress time.

Stress time - time during which high SAC stress consumption is calculated. Consider the set length for realistic bailout gas consumption planning.

Problem solving time - the time that is added to the time at the bottom in the event of a bailout. This includes time for problem solving such as switching the gas, deploying the buoy, alerting the team, bailing out, etc.

Loop volume - the volume of the breathing loop for calculating diluent consumption. For realistic diluent consumption planning, we recommend at least doubling the actual value to account for depth changes while on the bottom and minor gas leaks.

Metabolic consumption - physiological oxygen consumption. When adjusting, take into account possible emergency situations, dive conditions and minor gas leaks.

Ascent rate zones: set the ascent rates in three different depth ascent zones. Define the depth zones to the right of the imaginary ascent profile shown by the diagonal line. The ascent velocities in each zone are to the left of the imaginary profile.
Click on a specific entry and change it in the field below.

Descent rate: set the descent rate.

GF Low/High: gradient factors for modifying the ascent curve of the standard ascent. GF Low modifies the depth of the first stop (a lower value generates a deeper first stop). GF High determines the degree of tissue saturation at the time of emergence compared to the Buhlmann algorithm. Simplistically, the lower the number, the more conservative. The recommended setting is 40/75.

BO GF Low/High: setting gradient factors for bailout ascent. It is assumed that when switching to bailout the diver wants to leave the water faster. For this reason it is possible to set a slightly more aggressive GF.

END: Setting the equivalent narcotic depth. Generates a warning if the END is exceeded when using a breathing mixture at a given depth. The optimum END setting is 28 - 30 m.

Oxygen is Narcotic: Indicates whether the narcotic potential of oxygen is included in the END calculation.

Deco algorithm: choose from two Decompression Algorithms. ZHL16B is originally designed for decompression tables. ZHL16C is originally designed for dive computers and is slightly more conservative.

Salinity: choose in which water you will dive - sea water, fresh water or defined salinity EN 13319 corresponding to approximately brackish water.

Last stop depth: specify the depth of the last decompression stop.

Deco step: this item specifies the decompression step size, eg. 2/3/6m or 7/10/20ft.

End pressure: Safety margin of pressure in the cylinder (how much must remain in the cylinder)

Cylinders setting

Setting up scuba tanks and mixtures. This app assumes that divers own a certain stock of cylinders in their warehouse, which they use over and over again, selecting the ones that are suitable for a given dive. In particular, rebreather divers have filled bailout cylinders that they usually do not use during the dive. For this reason, this part of the app is conceived as a kind of personal cylinder storage. You can add, edit and remove cylinders at will.

Note: When you enter a schedule, you are selecting a mixture from this store and cannot edit it at that time. However, it can be edited in the plan itself.

On-board oxygen: oxygen settings for Rebreather. Item cannot be removed. The volume and pressure of the cylinder can be adjusted by pressing the red Edit button.

On-board diluent: diluent gas for Rebreather. Item cannot be removed. Volume, cylinder pressure and mixture can be adjusted by pressing the red Edit button. In the lower boxes, the maximum operating depth of the MOD mixture and the minimum depth of use with respect to the amount of oxygen (use of hypoxic mixtures) are calculated. The MOD is calculated with a PO2 0.2 bar lower than the setpoint for the bottom to ensure that the diluent is still usable for gas dilution.

M OC cyl. Room: open circuit cylinder storage

Adding a new mixture

Press the red + button to the right of the elevator.

Deleting the mixture

Drag the mixture line to the left. A red bin icon will appear. Tap it to confirm the deletion of the mixture.

Editing the mixture

Click on the mixture to open the editor. Adjust the volume of the cylinder, the actual pressure in the cylinder gas storage.

PO2 limit: the maximum oxygen partial pressure limit that determines the maximum depth of use of the mixture. A change in this factor has a major effect on the distribution of mixtures at depth during ascent and thus on their consumption. The default value is 1.4 bar.

MOD - maximum operating depth of the mixture according to the native Limit PO2

Minimum depth - minimum depth of use with respect to the amount of oxygen (use of hypoxic mixtures).

Analyzer settings

Set the required partial pressures to calculate the MOD maximum operating depth

Analyzer

Provides a remote display to the DNA analyzer

Connection to Analyzer

Click on the three dots on the top right. A list of available analyzers within 10 meters will be displayed. The analyzer number corresponds to the serial number. The assigned analyzer will continue to be associated with your mobile phone or app. To disconnect or change the analyzer the app is paired with, press the three dots again and then press the red Disconnect from Analyzer button.

Calibration

Calibration is required before the first use of the analyzer, without which the analyzer function is not available at all. Prepare the calibration gas and press the Calibrate button. There are two options to choose from: Air and Oxygen.

Please note: It is absolutely essential that the gas you actually use for calibration is washed out! Failure to do so will result in erroneous measurements that can result in serious injury or death.

After selecting the gas, apply the analyzer to the calibration gas (in the case of air, make sure that there is actually air on the sensor - for example, by sucking the gas out of the sensor compartment so that air is flowing to the sensor) and wait for the sensor voltage to stabilize (reading in mV). Then press the Calibrate button.

Measurements

Once the application has been calibrated with the analyzer attached, simply attach the analyzer to the gas being analyzed or connect it to a gas-connected flow restrictor and open the analyzed gas cylinder. Read the gas composition values on the display. The maximum operating depths (MOD) for the gas and the selected partial pressures are also displayed.
