  • To choose your gases, click on the "Gases" button and add or edit your gases as needed. You can specify your bottom gas, travel gas, deco gas, bailout gas, or custom gas. You can also specify the tank size, pressure, and cost of each gas.



  • To choose your depths and times, click on the "Depth/Time" button and enter your desired depth and bottom time. You can also enter your surface interval and repetitive factor if you are planning a multiple dive.



  • To choose your other settings, click on the "Settings" button and adjust your preferences as needed. You can change your units, gradient factors, conservatism level, water temperature, altitude, surface pressure, ascent rate, descent rate, minimum stop time, minimum gas time, minimum END, maximum ppO2, maximum CNS, and other parameters.



How to view your dive plan?




Once you have chosen your dive parameters, you can view your dive plan by clicking on the "Plan" button. You will see your dive plan in various formats, such as depth-time profile, gas-time profile, table format, or graphical format. You can switch between the formats by clicking on the tabs at the top of the screen.


Your dive plan will show you all the information you need for your dive, such as deco stops, gas switches, ppO2, END, gas consumption, CNS, OTU, and more. You can also see the color-coded warnings and alerts for any potential problems or hazards in your dive plan.


You can zoom in or out of your dive plan by using the mouse wheel or the buttons at the bottom of the screen. You can also print or save your dive plan by clicking on the "Print" or "Save" buttons at the top of the screen.


How to modify your dive plan?




If you want to modify your dive plan according to your preferences or conditions, you can do so by clicking on the "Modify" button. You will see a list of options that you can change in your dive plan, such as adding or deleting deco stops, changing gas switches, changing ascent or descent rates, changing conservatism level, changing gradient factors, changing water temperature, changing altitude or surface pressure, and more.


You can also use the "What If" feature to see how different changes will affect your dive plan. For example, you can see how changing your bottom time or depth will affect your deco time or gas consumption. You can also see how changing your gases will affect your ppO2 or END.


Once you have made the changes you want, you can click on the "Apply" button to update your dive plan. You will see the new dive plan in the same formats as before. You can also undo or redo any changes you made by clicking on the "Undo" or "Redo" buttons at the top of the screen.


What are the advantages of V-planner 3.91?




V-planner 3.91 has many advantages over other dive planning software and methods. Here are some of them:


Why use the VPM-B decompression model?




The VPM-B decompression model is one of the most advanced and accurate models for decompression calculations. It is based on sound scientific principles and empirical data from real dives. It takes into account the formation and growth of gas bubbles in the diver's tissues during decompression and tries to avoid them or keep them small enough to be harmless.


The VPM-B decompression model is well suited for today's technical diving because it can handle deep and extended dives with multiple gases and complex profiles. It can also handle dives with high helium content and low oxygen content, which are common in technical diving. It can also handle dives with high nitrogen content and high oxygen content, which are common in recreational diving. It can also handle dives with mixed gases, such as nitrox, trimix, triox, heliox, and more.


The VPM-B decompression model can also reduce your decompression time and gas consumption compared to other models, such as the Bühlmann model or the RGBM model. This is because it allows you to ascend faster and shallower without compromising your safety. It can also reduce your risk of DCS by minimizing the bubble formation and growth in your tissues.


Why use a bubble model for technical diving?




A bubble model is a type of decompression model that accounts for the formation and growth of gas bubbles in the diver's tissues during decompression. A bubble model is different from a dissolved gas model, which only accounts for the amount of gas dissolved in the diver's tissues and blood during decompression.


A bubble model is more realistic and accurate than a dissolved gas model because it reflects what actually happens in the diver's body during decompression. Gas bubbles are inevitable in diving, especially in technical diving, where the diver is exposed to high pressures and long durations. Gas bubbles can cause DCS if they grow too large or too fast and block the blood flow or damage the tissues.


A bubble model can help prevent or reduce DCS by avoiding bubble formation or keeping the bubbles small enough to be harmless. It can do this by adjusting the decompression stops and gas switches according to the bubble behavior and dynamics. It can also take into account the individual factors of the diver, such as age, fitness, hydration, temperature, and previous dives.


Why use V-planner 3.91 for multilevel dives?




A multilevel dive is a type of dive where the diver changes depth multiple times during the dive. A multilevel dive is different from a square dive, where the diver stays at a constant depth for the entire dive.


A multilevel dive is more common and realistic than a square dive because it allows the diver to explore different parts of the underwater environment, such as reefs, wrecks, caves, or walls. A multilevel dive can also reduce your decompression time and gas consumption compared to a square dive because it allows you to ascend gradually and use less gas at shallower depths.


V-planner 3.91 can handle complex multilevel dives with multiple gases and profiles. It can calculate your decompression stops and gas switches according to your depth changes and gas changes. It can also display your dive plan in a graphical format that shows your depth-time profile and gas-time profile. It can also export your dive plan to various devices that can guide you during your multilevel dive.


What are the drawbacks of V-planner 3.91?




V-planner 3.91 is not perfect. It has some drawbacks and challenges that you need to be aware of before using it. Here are some of them:
