Product Description

Simrad HALO 4 Pulse Compression Radar  

The first high-performance, open-array Radar system to make use of pulse compression innovation. Incorporating the best attributes of conventional pulse and FMCW Broadband Radar systems, HALO 4 Radar uses pulse Compression innovation to give an unmatched mix of long and short discovery Array, high target meaning, and minimal mess.

It is this devotion to technology that saw Simrad HALO called Winner of the National Marine Manufacturers Association (NMMA) Innovation Honor at the 2015 International BoatBuilders' Exhibit & Seminar (IBEX).

Solid State modern technology suggests marginal warm-up time as well as optimum ocean-going integrity, while compliance with upcoming Low Exhaust criteria makes HALO Radar secure to run in anchorages and marinas.
