  • What’s the difference between the 3D Shelf Edge chart and the 3D Shelf Edge Synthetic chart?
    The 3D Shelf Edge was created just like our other 3D charts, based on tens of different sources of sonar data, including our own. The various colors represent the different depths (red=shallow, yellow=less shallow, then to green, blues, and all the way to deep blues and purples for the deepest areas).
    The Synthetic was created similarly, but using additional data that interprets the hardness and ruggedness information of the ocean floor. The bright/whiter areas are rugged (significant depth changes over short distances) and the dim are flat. The brighter an area is, the more rugged the bottom. If you’re looking for lots of relief, look for bright areas. If you want flat areas, look for dim areas. If you’re looking for Tilefish, which often burrow into muddy bottom, you’ll probably want to look for dim areas (little to no relief) blue in color. The blue signifies soft muddy bottom, while red signifies hard, normally rocky bottom. If you’re targeting a big grouper, you’ll want rocky (red) big relief (bright areas).
