Convert SL2 to CSV

Understanding sl2 and csv file formats

SL2 files are proprietary data files generated by Lowrance sonar and fishfinder devices. These files store sonar log data, including depth, temperature, and GPS coordinates, in a binary format. CSV (Comma-Separated Values) files, on the other hand, are plain text files used to store tabular data, making them easy to open and analyze in spreadsheet applications like Microsoft Excel or Google Sheets.

Why convert sl2 to csv?

Converting SL2 files to CSV format allows users to analyze sonar data in spreadsheet software, perform custom calculations, and visualize trends. CSV files are also more accessible for sharing and further processing.
