Increase the memory of your Lowrance unit with these SD memory cards. Store and play back sonar graphs or GPS trip details on the screen or on your personal computer.
I use this memory card for my Lowrance GPS/Sounder unit to record and transfer my waypoints and saved sounder graphs to my PC at home. Used in conjunction with the MapCreate software, it provides a great facility in updating and altering waypoints for my Lowrance unit.
