The standard charts that can be created using nothing more than your own GPS and echosounder are nothing short of incredible. As well as looking beautiful, they have some really practical uses that can keep you in the fish.
Below is a simple chart created using Reefmaster, with the color scheme created to display the 20 - 30ft range in a different colour. The chart has then been exported from Reefmaster to a Lowrance format and displayed on an HDS plotter.
