Airmar R409C-LWM Transducer Ultra Wide Beam CHIRP

Overview

Who This Is For: Tournament anglers and serious recreational boaters running CHIRP sonar who want maximum target coverage and fish-finding sensitivity in a single transducer. If you fish competitive events or demand every edge, this wide-beam design gives you the coverage to find fish faster.

Product Summary: The Airmar R409C-LWM is a dual-frequency CHIRP transducer built to sweep more water under your boat than conventional narrow-beam designs. The 40° wide beam on low frequency paired with medium-frequency CHIRP gives you expanded coverage across the water column and precise target separation — meaning you'll see suspended fish and structure that other anglers miss. This is the transducer tournament captains are choosing when the bite gets competitive.

Key Features

• Ultra Wide 40° Low-Frequency Beam (40–60 kHz) — sweeps a much wider cone of water beneath your boat — you cover more ground with each pass and catch fish in the gaps other transducers leave behind.
• Dual-Frequency CHIRP (40–60 kHz and 80–130 kHz) — transitions from wide coverage to precise medium-frequency definition — wide beam finds the school, medium beam pinpoints individual fish and hard targets.
• 2 kW Power Output — delivers strong, clean signal return in deep water and poor conditions — your display stays crisp and responsive even on rough days or when fishing deeper structure.
• Depth and Water Temperature Sensor — real-time temp readings help you identify thermal layers and seasonal patterns — critical data for tournament planning and consistent catch rates.
• Xducer ID Technology — automatic recognition by compatible CHIRP displays — no manual setup or compatibility guessing, just install and fish.
• Urethane Housing — engineered to survive saltwater, UV exposure, and hard thru-hull installations — this transducer will last through years of tournament seasons.

Specs & What's Included

Compatibility: Works with any CHIRP-capable fish finder display (Humminbird, Lowrance, Simrad, and others that support 40–60 kHz and 80–130 kHz CHIRP). Thru-hull installation only. Fiberglass hulls only with deadrise 0° to 25°. Not sure if this fits your boat and display? Call or text us at (833) 831-4077 — we'll tell you straight.

In the Box: Airmar R409C-LWM transducer only. Bare wire connection — you will need to splice to your boat's transducer cable or use an adapter harness specific to your display unit. Mounting hardware and installation materials sold separately.
