Raymarine’s Quantum 2 solid-state radar uses the latest Doppler target identification, plus CHIRP pulse compression, to identify moving and static targets at long and short ranges. Doppler processing detects the radar echo’s frequency shift in the return signal to determine moving versus stationary targets. Color-coding indicates whether targets are getting closer (red) or moving away (green). Quantum 2 also highlights and color-codes potentially dangerous static targets within about 650 feet forward of the boat. From $1,950. Raymarine, Nashua, New Hampshire, (603) 324-7900. raymarine.com
