Fishing ocean temperature breaks is a tried-and-true method of finding kingfish, dolphin, marlin, sailfish, tuna and wahoo. Schools of bait tend to follow such edges as they might follow a game trail. Predatory fish usually aren’t far behind. Access to sea-surface temperatures is where a satellite service such as SiriusXM Marine comes into play. With the company’s Marine Offshore package and compatible hardware, you access high-resolution SST images on a multifunction display (MFD).
