Thru-Hull CHIRP Transducers Depth and Temperature 2 kW – 3 kW Models These externally mounted 2 kW–3 kW depth and temperature transducers feature a rugged epoxy housing and are compatible with fiberglass, wood, aluminum, and metal hulls. Ideal for vessels 40' (12 m) and larger, they are rated for up to 22° deadrise and deliver high-power performance for demanding offshore applications. Model Description Max Depth CHIRP Frequency Bands Beamwidth (Typical) R509LH Combines Low CHIRP for deep-water performance with High CHIRP for maximum target resolution— delivering depth capability to 10,000' for deep dropping and clearly defining targets along bottom structure. 10,000' (3048 m) 1500' (457 m) 28–60 kHz (Low) 130–210 kHz (High) 23°-9° port/stbd x 11°-5° fore/aft 8°–4° R509LM Combines Low CHIRP for deep-water performance with Medium CHIRP for a balance of depth and detail— delivering depth capability to 10,000' for targeting swordfish, tuna, and other deep-water species, with broader coverage for versatile offshore fishing. 10,000' (3048 m) 3000' (914 m) 28–60 kHz (Low) 80–130 kHz (Medium) 23°-9° port/stbd x 11°-5° fore/aft 13°–8° R509LHW Combines Low CHIRP for deep-water performance—ideal for targeting swordfish, tilefish, grouper, and other deep-water species—with High-Wide CHIRP for expanded coverage and high-frequency detail—ideal for locating bait schools and pelagic species in the upper water column to 500'. 10,000' (3048 m) 500' (152 m) 28–60 kHz (Low) 150–250 kHz (High) 23°-9° port/stbd x 11°-5° fore/aft 25° constant 2-3 kW Max depth 10000' (3048 m) HIGH WIDE LOW MED HIGH 0' (0 m) 3000' (914 m) 6000' (1829 m) 10,000' (3048 m) How to Choose — R109 / R409 / R509 Series • Maximum offshore depth & resolution → LH variants • Balanced offshore depth & mid-range coverage → LM variants • Excellent deep-water performance with wide pelagic coverage → LHW variants • Wide midwater coverage with strong offshore depth → LWM variants Frequency and Performance Options All models include a Low CHIRP frequency band for maximum deep-water performance. The second CHIRP band—High (H), Medium (M), or High-Wide (HW)— determines the level of detail and coverage under the boat. LHW models expand coverage under the boat, making them ideal for scouting large areas and locating pelagic species. 587.2 mm (23.12”) 169.7 mm (6.68”) 114.3 mm (4.50”) Hull Backing block Fairing Transducer Temperature sensor Stufng tube Cable BOW> 444.5 mm (17.50”) Greater Power.
