Having the right tool for the job makes the job easier and provides better results. The right tool for covering deep water haunts of swordfish, tuna and other species is a 2 kW low/medium frequency transducer. The CHIRP-ready R111LM delivers the deep water performance of the low frequency out to 6000 ft plus the detail-delivering returns produced by the narrower beams of the medium band. CHIRP technology delivers 5 to 10 times greater detail and resolution than conventional frequencies. This transducer delivers up to 87 kHz of total bandwidth in a single installation. The transducer is installed inside the hull of the boat in the included yellow tank. The tank is cut to the boats deadrise angle and affixed inside the hull to assure that when the transducer is installed inside the tank, it is properly oriented for optimal performance. The R111LM is a popular choice for customers not wanting to drill any holes in their hull and for trailered boats or multi-hull boats.
