• Supports both metric (meters, °C) and imperial (feet, °F) units
• Sort dives chronologically (oldest or newest first)

Installation

git clone https://github.com/derekspelledcorrectly/shearwater-csv.git

Common options:

• -i - Use imperial units (feet and °F)
• -r - Reverse sort order (newest dives first)

Output Format

The CSV file contains the following columns:

• # - Dive number
• Location - Dive location

• Duration (min) - Dive duration in minutes
• MaxDepth (m/ft) - Maximum depth in meters or feet
• AvgDepth (m/ft) - Average depth in meters or feet
• MinTemp (°C/°F) - Minimum temperature
• MaxTemp (°C/°F) - Maximum temperature
• AvgTemp (°C/°F) - Average temperature

Example Output

#,Location,Site,StartTime,Duration (min),MaxDepth (m),AvgDepth (m),MinTemp (°C),MaxTemp (°C),AvgTemp (°C)
