Match radar band to vessel class (X-band under 3,000 GT; X+S dual-band at 3,000 GT and above per SOLAS), size the scanner for required angular resolution, confirm ARPA target capacity and ECDIS integration protocol, and verify IMO MSC.192(79) type approval. For replacement scenarios, properly reconditioned radar performs to OEM specification at 40–60% lower cost.
X-band for short-range high-resolution navigation; S-band for long-range all-weather penetration. SOLAS dual-radar vessels (3,000 GT+) carry both.
Yes — provided IMO type-approval is intact, hardware unmodified, and firmware within the approved version range.
