New Features
Introducing PINGVerter v1.0.1
PINGVerter is a new Python-based convertor for sonar logs collected with consumer-grade fishfinders. PINGMapper now uses PINGVerter as the primary processing engine for decoding sonar logs. It is designed to ease adding support for new sonar data acquisition platforms and filetypes. Find out more below...

Support for Lowrance®
It is now possible to process sl2 and sl3 files with PING-Mapper. All of the processing features PING-Mapper made possible for Humminbird® are now available for Lowrance®. This includes EGN corrections, shadow removal, depth detection, substrate mapping, etc.

~1.3x Speedup
PINGVerter and PINGMapper now feature an improved mechanism for reading sonar logs, inspired by sonarlight. This results in ~1.3x speedup when running the Small Dataset Test.
Recently released v2.1.0
The recently released v2.1.0 also had important improvements and bug fixes including:
- Sonar Log Filtering
- Coverage and Trackline Shapefile Export
- Fix to Bankline Shapefile Export
