+## Format Notes
+
+- **File Version 5**: Standard format for wet caving devices
+- **File Version 6**: Enhanced format for dry caving devices with optional Lidar data
+- **Byte Order**: Both V5 and V6 use little-endian (LSB first) for all 16-bit values
+- **Compatibility**: V6 is fully backward compatible with V5 for all common fields
+- **Lidar Data**: Only present in V6 format when device captures 3D point cloud data.
+- **Magic Bytes**: Used for data validation and format detection
+- **Data Length**: Specifies the total bytes of Lidar data (must be divisible by 6)
