 If you are not educated in the workings of decompression

procedures please seek out training from a reputable internationally recognized training agency before using this product.

 Using pure Oxygen or Oxygen enriched gases, Trimix,

Heliox or any gas mixture that contains an Oxygen content more or less than 21% (straight air) needs special safety measures and appropriate training. Please consider the general safety considerations of using breathing mixtures other than air.

 No decompression table, program, schedule or output can

ever assure that you will not be subject to decompression sickness. Use of this software is at your own risk.

 If the diver uses the wrong value of the gas mixture he /she

or the dive computer could calculate insufficient decompression time (EAD, END, PO2, PN2) or oxygen toxicity (MOD, CNS, OTU etc.). Both situations could result in death or serious injury.

 Avoid risky situations which are marked in this manual with

CAUTION and STOP

 Do not use Nautilus Dive Planner for actual dives which

you have not been trained for.

General InformationGeneral Information

This user’s guide is designed to help the certified diver, nitrox diver, mixed gas diver, or rebreather diver to: understand the

need and application of planning dives that require decompression planning. This manual does NOT purport to be a replacement for certification courses in the subject area or will it provide information on how to conduct the operations of a single dive or series of dives. Users who utilize the values presented in NAUTILUS accept all risks of use.

This user’s guide will provide information as to the operational use of the NAUTILUS Dive Planner Software program.

The Nautilus Dive Planner Software is for the trained and certified diver, and gas mixing technician. Nautilus Dive Planner Software requires that the user analyze and verify BOTH the oxygen and helium content of any gas that will be used prior to completing any dive that has been planned with the Nautilus Dive Planner Software program. A complete log should be maintained for all gas mixtures. It is the USER’S SOLE RESPONSIBILITY to properly record the gas percentages and label the cylinder being analyzed appropriately. Improper gas analysis and transferring that improper analysis to the Nautilus Dive Planner Software may produce decompression results that

can cause injury, disability, or death.

Welcome to NAUTILUS Dive Planner Software. NAUTILUS is the new generation of Technical Dive Planning Software and the most comprehensive dive planning tool developed during the last few years. We are now 15 years into desktop dive decompression software products yet most of the products on the market are limited in their ability to deliver a wide variety of features and functions. Many have been homegrown products that have gained cult-like loyalty by some users, but still lack the full features and variable controls desired by most of today’s advanced and technical divers.

The introduction of NAUTILUS Dive Planner Software is a new approach to planning decompression dives and in the manner in which it delivers the myriad of information a diver needs to efficiently plan, compare, and analyze dives. It makes no difference to NAUTILUS if the diver is using one gas, three gases, or ten gases. It also makes no difference if the diver will dive on conventional open circuit scuba or closed circuit scuba, or a combination of both—NAUTILUS manages it all!

algorithms. NAUTILUS allows the user to make adjustments to the outputs of those algorithms through the use of gas selections, avoiding stops at particular depths, selecting maximum PO2 levels, choosing stop time or runtime, inserting micro-bubble minimization deep stops and much more!

This Version of NAUTILUS DIVE PLANNER introduces a wide range of new and exciting features that were previously unavailable to desktop decompression planning. With NAUTILUS users are able to make detailed plans and then perform a simulated dive based on that information. During the simulation NAUTILUS will track and inform the user of a wide variety of information to help you plan and execute an actual dive. NAUTILUS is not intended or designed for the novice SCUBA diver, but rather for the experienced diver or a diver who is enrolled in a qualified training course where NAUTILUS is being introduced.

NAUTILUS is a control panel for the technical diver or instructor. The NAUTILUS control panel allows the user to make rapid selections of important components of the dive plan in an easy-to-understand manner. By utilizing “tabs” similar to that on a notebook the user can quickly navigate to the area they want to work in, make the selections, save that information and then plan the dive and create the table output.

NAUTILUS allows the user to select from not one but a variety of popular and proprietary decompression

Nautilus Dive Planner Software comes in six versions. Each is a complete full working version of NAUTILUS but is limited in the maximum operating depth. These depth levels correspond with popular technical diving certification levels. We do not limit the purchase of any of the versions except for one. The licensee of one version will be able to purchase upgrades to the next depth version.

Nautilus Dive Planner Software uses tabs inside the program to allow for navigation to the individual function pages. They are arranged left to right in the order that the user will access them after the initial setup. Ultimately once the users “standard” preferences are set the tabs will not need to be accessed until the next time preferences need to be modified. This section will describe each TAB set. The next section will take you though each of them with screen shots.

We anticipate that the most popular versions will be Nautilus 140, 225, and 330. The Nautilus RE (research) version is limited in availability to laboratories, universities, military, and commercial diving companies only.

Each version of Nautilus allows for complete decompression planning with either open circuit, closed circuit or a combination of those diving modes. Users can select from air, oxygen, nitrox, trimix, heliox, nitrox setpoint or heliox setpoint gas modes. Users can plan square, multilevel, or repetitive dive profiles with complete control and interchangeability of diving modes.

Nautilus Dive Planner is the only decompression planning software that incorporates the full functions of a true decompression planning tool with a choice of decompression algorithms and models.

1.31 GENERATE PROFILE:

Here is where the actual dive profile is entered and viewed in a simple graphical display. Square profile, multilevel profile, and repetitive dives are easily plotted here and the decompression profile is viewed.
