Airmar’s M135M includes a plastic mounting base which is aligned to the centerline and secured inside the hull. Then it is filled with non-toxic antifreeze.\u003c\/p\u003e\n\u003cp class=\"sr-intro\"\u003eThe transducer is inserted into the base and adjusted for the proper deadrise offset, ensuring the beam is shooting straight down for maximum echo returns. The eco-friendly coolant is the best medium to transmit through solid fiberglass and into the surrounding water.\u003c\/p\u003e\n\u003cp class=\"sr-intro\"\u003eThe major benefit of an in-hull transducer is no protruding features on the exterior of the hull, making it the perfect choice for trailered or lifted boats. Designed for smaller boats up to 11 m (36') with a solid-fiberglass hull. This transducer is available in two options: one with an OEM connector designed specifically for your fishfinder, and another as a Mix and Match™ Transducer version.\u003c\/p\u003e\n\u003cp class=\"sr-intro\"\u003eThe Mix and Match™ transducer has a 9-meter (29.5’) cable with a standard connector, plus a 1-meter (3’) adapter cable to connect it to your fishfinder. When placing your order, make sure you know which connector type your fishfinder requires.\u003c\/p\u003e\n\u003cdetails class=\"sr-specification-panel\" open=\"\"\u003e\u003csummary\u003eTechnical
