Whether you want to explore creek channels, cruise in the open sea or along the coast, catch fish both offshore and from canal banks, you cannot do without a chart that gets more and more precise and reflects the ever-changing conditions.
Anglers can use SonarChart™ for their favorite fishing activity. Freshwater fishermen know how important it is to have shallow water details for lake or river beds in order to spot holes or other underwater structures which are the best places to find species like carp, tench or bass. Surfcasters, casting bait from shore, will be able to rely on very dense detail, with contours every 1 and 3 feet. This way they will be able to better identify wave breaking points where species like sea bass and gilthead bream normally linger. Others who like fishing in the open sea, going after tuna or snapper can also find appropriate contours.
SonarChart™ is included with plotter GPS cards like Navionics+, Platinum+ and HotMaps Platinum. You can also get it on your Gold or HotMaps Premium by using Navionics Updates.
