Garmin introduced its Fantom radar, with MotionScope technology (using the Doppler effect), as an open array in early 2016. The company added 18- and 24-inch domes ($1,599.99 and $2,799.99) to the lineup in November. MotionScope highlights targets in different colors as they move toward or away from your boat. Both units also offer pulse compression technology for high-resolution returns, low power consumption, and instant on with no delay from warming up. A MARPA setting allows simultaneous tracking of 10 targets. Fantom detects targets as close as 20 feet and as far as 48 nautical miles.
