The SS270W’s extra wide coverage delivered to a dual frequency, split-screen sounder gives fishermen a wider view of what is going on under the boat. The SS270W gives you four times the beam width at 200 kHz than other 1 kW, high performance transducers. Since the beams are the same at both frequencies, a split screen fish finder display will clearly show the same water column and bottom coverage. Fish may also appear as arches. More fish will be marked while cruising, trolling, drifting, or at anchor.
