Why Em-trak Stands Out

  • Em-trak’s AIS processing engine is highly optimised for:

    • Dense traffic areas

    • Weak or obstructed signals

    • Long-range reception

    • Continuous duty cycles

  • Robust chassis, IP ratings, vibration resistance and long-term durability ensure reliable operation in harsh marine environments, a must for NZ conditions.

  • All systems connect easily with NMEA 2000, NMEA 0183, USB, Wi-Fi and major MFD/plotter brands. Ideal for both upgrades and new installations.

  • Compact sizing, flexible mounting and intuitive interfaces reduce installation time and ongoing maintenance.

  • Commercial-level performance at an accessible price point, with low ongoing running costs and a strong track record of reliability.

  • Em-trak offers extensive online resources, firmware updates and documentation, backed by global technical support and a strong warranty programme.
