The SAILOR 6216 VHF DSC Class D radio by Thrane & Thrane is now part of the SI-TEX Marine Electronics lineup. Tested under tough conditions, such as in heavily trafficked and urban areas where airwaves can be overwhelmed with land mobile networks, the 6216 has proven itself. Large rotary knobs and buttons facilitate operation in a range of conditions. Professional-grade features include a powerful 6-watt built-in loudspeaker, 30-watt loud hailer with talk-back and foghorn functions, remote speaker mic options and a DSC Distress button, along with IPX8 and IPX6 waterproof rating, making it suitable for installation in exposed locations. The 90-second-replay function allows for the review of important messages such as safety advisories or critical fishing information.
