Currently have a Lowrance 522C IGPS. The 5″ screen is a little small when I split the screen to show map chip features and sonar reading. SO, thinking of ordering a second unit to run sonar on one unit and mapping on the other unit. Question is what’s the best option a 5300 GPS to use a map and use the 522 as a sonar unit. Any thoughts and recommendations would be much appreicated.
Thank you in advance
