Buyer’s Guide — How to Choose Marine Radar

The biggest decision is range vs dome size. Larger domes offer better long range performance, but 18 inch units are more than adequate for most cruisers.
Doppler processing is now essential — it highlights moving targets and makes collision avoidance far easier.
Finally, choose radar that integrates cleanly with your existing chartplotter. Garmin works best with Garmin; Raymarine with Raymarine.

Which Radar Should You Choose?

Choose the Fantom 18 for most cruising boats.

Choose the Fantom 24 for maximum range offshore.

Choose the Quantum 2 if you use Raymarine.
