E70498
Marine Electronics Specialist Insight: The Quantum 2 (MPN E70498) is the industry benchmark for compact, intelligent radar. This "No Cable" version is the ideal solution for upgrading an existing Quantum system where cables are already chased through the hardtop, or for fully wireless installations using built-in Wi-Fi. It features Doppler target processing, which instantly color-codes moving threats—red for approaching and green for retreating—drastically simplifying night navigation.
Intelligent Safety with Doppler Target Processing
The Raymarine Quantum 2 Q24D (MPN: E70498) brings military-grade situational awareness to the recreational captain. Unlike traditional radars that only show "blobs" on a screen, the Quantum 2 utilizes Doppler technology to detect moving radar echoes. By comparing frequency shifts, the radar automatically highlights moving targets in contrasting colors, allowing you to identify dangerous incoming vessels in a split second.
This solid-state radome uses CHIRP Pulse Compression to deliver superior target separation at both extremely close ranges (as close as 18 feet) and long ranges up to 24 nautical miles. The E70498 is designed for rapid deployment, featuring Instant-On technology that eliminates the warm-up time required by older magnetron radars. Weighing up to 50% less than traditional units, it is the perfect choice for sail and power vessels alike.

Frequently Asked Questions
1. Why is this model sold without cables?
MPN E70498 is designed for replacement scenarios or custom installs. If you are replacing an original Quantum or Quantum 2, you can use your existing power/data cables. If this is a new install, you will need to purchase cables separately.
2. Can I use this radar purely wirelessly?
Yes, Quantum 2 can transmit radar data via its built-in Wi-Fi to Axiom displays. However, you will still need to provide a 12V or 24V power connection to the radome via a Raymarine power cable.
