Conclusion: the MRX is the ultimate in really portable traffic detection systems for pilots on a budget.  These products are a pilot's best friend in busy airspace and it truly is amazing how it picks up traffic before you can possibly detect it yourself. Priced at USD499 it is a no-brainer to order one right now and make flying for you and your passengers much safer."
