Breath Hold Dive Log contains all the fields that you might need to make logging your dives quick and easy.

Record details such as:

• the dates and times you dived
• who your dive buddies were
• your dive locations
• weather and water conditions
• dive types, disciplines, weight and kit used
• your max depths, breath hold times and breath up durations
• notes about the trip and and any species encountered

Using one or more marker pins the map will display all dive locations where they have been provided.

Tapping the marker pin will display a label containing the log name, the trip date and the location name.

Tapping the label will navigate to a read only version of the 'Dive Details (read only)' page. No changes to the record can be made here.

Use the navigation bar to return to the 'Dives Map' page.

The map can be zoomed and panned in the usual manner.

Use the navigation bar to return to the 'Home' page.

When navigating from the 'Dives List' page the full details of either a new or an existing record is displayed.

The scrollable screen is split into sections that can be collapsed or expanded.

For a new record the 'Log Details' and 'Location' sections are expanded by default.

A section's expandable state is saved with the record details.

Each section has an information button that gives a brief explanation of the fields in that area.

In order for a record to be saved the three mandatory fields, 'Log Name', 'Trip Date' and 'Location Name' must be complete.

The dive location for the record is shown as a marker pin on the map. It is only possible to zoom, not pan.

It is only possible to edit the dive location coordinates using the 'Edit Map' button.

The 'Reset' button is only available for new and unsaved details and enabled once the mandatory fields are complete. It will reset all fields to their default values.

The 'Delete' button is only available for existing saved details and will delete the displayed dive record returning to the 'Dives List' page.

It is only possible to return to the 'Dives List' page by using the 'Cancel' or 'Save' buttons. There is no back navigation.

On return to the 'Dives List' page any changes to the log record name, location or trip date will be reflected.

It is only possible to navigate to this page using the 'Edit Map' button when editing the dive details.

To manually place a marker pin on the map for the dive location pan and zoom as necessary. Tapping the map will place the marker pin accordingly.
