Description
Raymarine Cyclone Radar with 3-Foot Open Array – T70491
Eliminating the gap between sleek aesthetics and high-performance tracking, the Raymarine Cyclone with a 3-foot open array is a masterpiece of maritime engineering. This radar is specifically designed for American center consoles and fast cruisers where space is at a premium but open-array performance is required. For the USA operator, the 3-foot Cyclone provides an impressive 60 RPM rotation speed, delivering near-real-time target updates and a cinematic radar view that is essential for navigating high-traffic inlets or tracking birds at long distances during offshore fishing trips.
The Cyclone series features an aerodynamic “wing” design that minimizes drag and allows for operation in winds up to 100 knots. It incorporates Raymarine’s advanced Doppler technology to instantly color-code moving targets, making hazard identification intuitive and fast. With its low-profile 13.2-inch height and professional-grade CHIRP pulse compression, this 3-foot radar offers the American market a high-speed, high-definition navigation tool that redefines the standard for modern radar systems.

Common Questions for Raymarine Cyclone Radar
The 3-foot Cyclone requires a 12V or 24V DC power source that can support minimum marine cranking amps during peak transmission. While it has no gallons per hour rate, the Raymarine Cyclone Radar provides a powerful 55W pulse compression output, making it highly effective for short-to-mid-range coastal navigation.
This antenna size is the optimal boat hull application for fast center consoles because it offers low windage and high-speed target updates. The Raymarine T70491 Radar provides elite target separation, allowing the Raymarine Cyclone 3-Foot user to identify navigational markers and other vessels with incredible clarity in high-traffic zones.
Regularly check your sacrificial aluminum anode locations to ensure the pedestal is protected from the corrosive effects of the saltwater environment. Keeping the Raymarine Cyclone T70491 clean with fresh water ensures that the aerodynamic wing-style array continues to rotate at 60 RPM without any mechanical drag or salt buildup.
For the best results, use Genuine Raymarine Parts for the RayNet and power wiring to ensure the pedestal receives the necessary voltage. The Raymarine T70491 Antenna relies on these high-quality connections to deliver real-time ARPA tracking and Doppler Target Analyzer data to your Axiom display without any signal loss.
The Cyclone utilizes a brushless, solid-state motor that does not require FC-W engine oil capacity monitoring or seasonal oil changes. This Raymarine 3-Foot Radar is engineered for maximum reliability with zero maintenance, using internal high-grade seals to protect the moving parts from the harsh conditions of offshore boating and fishing.
