Go Free Wireless Toolkit
The GoFree open protocol data strategy groups data into 5 different Tiers. Access to data varies, but essentially all data is free to use if it enhances the desirability of Lowrance MFDs.
Specifications for Tier 1 and Tier 2 (view only) are available to download for free - follow the links below.
