Raymarine Quantum 2 Q24D
The Raymarine Quantum 2 Q24D is a lightweight, solid-state CHIRP pulse-compression radar optimized for nearshore fishing and sportfishing craft that want fast updates and easy integration with multifunction displays. It undercuts many larger systems on price and installation complexity while providing Doppler motion detection that helps anglers spot birds and bait schools; however, it sacrifices some long-range capability compared with the higher-power open-array and premium Furuno options. For crews focused on coastal fishing efficiency and simple onboard networked systems, the Quantum 2 offers an appealing mix of affordability and modern processing features.

Review Summary
"Boat owners like the Quantum 2 Q24D for its compact, low-power Doppler performance and value for small to mid-size fishing boats, but some long-term users report limits in long-range detection and occasional false-motion alerts versus larger magnetron systems. It’s considered a good affordable Doppler dome if you accept its range trade-offs."
