+== Download dives from a dive computer
+
+Download of dives is possible from dive computers with a FTDI USB interface, or with a Bluetooth interface.
+
+First, establish a link between the dive computer and the mobile device. 
+
+For USB dive computers, USB cables "normally" used
+for uploading dives to a desktop/laptop computer do NOT work: these cables often have a full-sized male USB plug
+on one end which plugs into the USB port of a desktop/laptop computer. For downloads to a mobile device
+one needs a USB OTG (USB On-The-Go) cable. In most cases it is required to plug the USB
+cable "normally" used with the dive computer into a USB OTG cable which, in turn, plugs into the mini-USB
+receptacle of the mobile device. The
+OTG cable often has a full-size female receptacle at one end which accommodates the full-sized male plug
+of the USB cable "normally" used (see image below). This means that two cables are used to connect the dive computer to the mobile device.
+
+image::mobile-images/USB-OTG.jpg["FIGURE: USB-OTG cable",align="center"]
+
+For Bluetooth-equipped dive computers, establish a Bluetooth connection between the dive computer and the
+mobile device. Use the tools on the mobile device to achieve this. For of Android mobile devices,
+the Settings -> Bluetooth tool is probably appropriate. Ensure pairing of the dive computer and mobile device.
+_Subsurface-mobile_ performs communication using both Bluetooth and Bluetooth-low-energy (BTLE).
+The appropriate choice of Bluetooth communication is made by the software and the user need not be concerned with this.
+
+With propper communication between dive computer and _Subsurface-mobile_ having been set up, dive download is simple.
+From the main menu, tap _Manage dives ->  Download from DC_. A screen is shown requiring that the user specify
+the names of the vendor and model of the dive computer. For instance, when using a Shearwater Petrel 2 dive
+computer, the vendor is _Shearwater_ and the Dive computer name is _Petrel 2_. From the two dropdown lists
+at the top of the screen, select the correct vendor and dive computer names (see image on the left, below). If
+using a dive computer using a Bluetooth connection, then tap the check box labelled _Bluetooth download_.
+
+Now tap the button labled _DOWNLOAD_. The downloaded dives appear in the bottom part of the screen, the
+most recent dive at the top (see image on right, below). Be patient because the download can sometimes take a few mimnutes.
+Each dive has a check-box on the left hand side, used for selecting which dives need to be added to the
+_Subsurface-mobile_ dive list: dives that are not checked are ignored. With the appropriate downloaded dives
+having been checked, tap the button at the bottom left labled _ACCEPT_. All the selected dives appear on
+the _Subsurface-mobile_ dive list. The downloaded dive information can now be edited as described in the section
+above xref:S_Edit_Dive[Edit a dive].

+== Viewing the dive location on Google Maps
+
+The site of a specific dive can be viewed in two ways using the _Details View_. 
+The Action Bar at the bottom has a GPS pin on the
+left hand side. Tap that pin and the dive site is shown in Google Maps. Close Google Maps by using the Android _Back_ button.
