Beginners guide - A tutorial

    This tutorial is intended to get first-time users started with Apnealizer as smoothly and quickly as possible.

    Before we start

    If this is the first time you use the USB cable to connect your dive computer to your mac, then you may need to install some sort of USB driver on your mac in order to be able to use the download function. Every dive computer manufacturer has a different procedure for this, so please check your dive computer manual. If your dive computer comes with its own dive software then installing it might also install any USB driver needed.

    Let’s start!

    When you open Apnealizer for the first time, there will be some demo dives already included in the installation. You can choose to keep these or delete them, it’s up to you. We recommend that you keep them for a while since they show some nice features of Apnealizer.

    Here are two ways to import dives into Apnealizer

    • Import from a file
    • Direct download from your dive computer via the USB cable

    This tutorial will go through how to download dives from a dive computer. To import from a file see section Import dives from files

    Open the download dialog

    To open the download dialog select in the menu bar the following:

    File->Import Dives->Dive Computer Download

    You will be presented with the following download dialog

    Select the Vendor and Model of your dive computer. So for example; if you have a Suunto D5, then you should select vendor to be Suunto and the model to be D5. If your dive computer can be connected to both usb and bluetooth (BLE) then it is possible to choose which option you want. USB is recommended over bluetooth because USB has a faster download speed and is more stable. When you download for the first time, you should choose USB.

    Leave the Download Option at “Import only new dives”

    Advanced settings

    You could start the download process now if you wanted to. However, there are some very nice extra settings available that we shall look at first. Click on the Advanced Settings arrow down button (image_arrow_dwn_button)

    You will be presented with a larger download dialog with some additional options.

    The first option, Auto-set dive site can be used to tell Apnealizer to set a location/dive-site name to each dive that is downloaded. Setting a site name to every dive is strongly recommended because it will simplify keeping track and filtering of your dives in the future.

    If you know that all of your dives in your dive computer are from the same dive site, then you can check this option and write an appropriate location name in the text field. If your dive computer contain dives from a lot of different places, then it might be better to leave this option unchecked.

    Note: You can later manually set the a site name of any dive at any time. See How to set a dive-site/location to your dives

    The second option Hide dives… is a great way to hide “unimportant” (setup/warmup/fun) shallow dives. Apnealizer still downloads the dive so they are not lost or discarded, they are just hidden from the main dive view. So for example if you don’t want to see any of your warmup or fun dives, check this option and set the value to 10 meters. This will hide all dives shallower than 10 meters. If you make a mistake it’s easy to un-hide dives see How to hide/ show dives. Hiding dives is a great way to set focus on the dives that interests you without loosing any data.

    The next option, Set date and time on dive computer before download is pretty self explanatory. Not that not all dive computers support this function.

    The last option is different depending on which type of dive computer you have selected. If you are using a bluetooth (BLE) compatible device (as in the picture) then you should see a button which tells Apnealizer to forget the previously used device. This should should be done you have used your dive computer with bluetooth on another device like a mobile or other computer.

    If you are using an older device with USB-serial connection, then the last option will show a setting to manually set the com port setting, This is used for troubleshooting if you are having problems with the USB connection. This option should be left unchecked under normal circumstances.

    Connect your dive computer to your mac

    Connect your dive computer to your mac via the USB cable. Note that some dive computers also requires that you put it into a download mode (like the Mares Smart Apnea) check your dive computer manual for the correct procedure.

    Download!

    Press the Import Dives button!

    If all goes well Apnealizer will connect to your dive computer and download every dive from the dive computer memory. You should see a blue progress bar progressing across the dialog.

    If you run into trouble and get some sort of error message check the Download troubleshooting section.

    Start Using Apnealizer

    Apnealizer should now be populated with some dives and be ready to be used. The application should look something similar to the screenshot bellow.

    For a detailed description of the layout of the app see Apnealizer Overview

    Worth noting is that to the far left is the source selection sidebar, here you decide what shall be populated in the rest of the application. To the right of the sidebar is the dives list, here you select which dive you want to see in the graph view which is located to the right of the dives list. To the far right is the dive inspector pane and graph settings controls.

    Select a dive in the dive list with the mouse.

    The graph should now be populated with the dive profile of the selected dive. You should also see that the dive inspector pane (located on the far right) is populated with details of the selected dive.

    From here, there are a lot of things you can do. Bellow are some topics for further in-depth reading and learning. Enjoy!
