Airmar B285HW Transducer 1kW Wide Beam CHIRP

Overview

Who This Is For: Anglers running Chirp-ready fishfinders who need wider bottom coverage without sacrificing detail. If you fish deep structure, suspended fish, or want to cover more water column on each pass, this wide beam transducer delivers twice the coverage of standard high-frequency units.

Product Summary: The B285HW is a thru-hull bronze transducer built to show you what standard narrow beam units miss. It runs 150–250 kHz across a constant 25° beam width — meaning you get consistent, crisp sonar images from shallow to deep water. That wider cone means better coverage of suspended fish and structure that sits between tight beam lines, all without the performance hit you'd expect from going wider.

Key Features

• 150–250 kHz Broadband Chirp — transmits across a full frequency range instead of single bands — your fishfinder can process the entire spectrum at once, giving you better target separation and sharper bottom definition.
• Constant 25° Wide Beam — twice the bottom coverage compared to narrow beam high-frequency transducers — you'll see suspended fish and structure in the water column that narrow beams miss completely.
• 1 kW Transmit Power — enough punch to cut through weeds, turbidity, and depth to reliably mark fish and structure without overwhelming your display.
• Depth and Temperature — real-time water temperature at any depth — helps you pattern fish and confirm thermocline location without a separate sensor.
• Bronze Housing — durable saltwater-rated construction — won't corrode in inshore or offshore environments where aluminum would fail.
• Xducer ID Technology — automatic transducer recognition by compatible fishfinders — plug it in and your unit configures itself; no manual setup required.

Specs & What's Included

Compatibility: This transducer works with Chirp-ready Airmar and compatible third-party fishfinder systems. It requires a mix-and-match cable — the cable is not included. You'll need to verify your fishfinder supports Chirp and confirm cable compatibility before ordering. Not sure if this works with your setup? Call or text us at (833) 831-4077 — we'll tell you straight.

Installation Specs: Designed for boats up to 30 feet with hull deadrise up to 24°. Urethane acoustic window handles thru-hull mounting in fiberglass hulls.

In the Box: B285HW transducer only. Cable sold separately — you'll need to order the correct mix-and-match cable for your fishfinder model.
