SI-TEX ColorMax 5 Chartplotter is a compact 5-inch chartplotter designed for boats that need essential navigation features in limited helm space. The active matrix color LCD, external antenna setup, and weatherproof construction make it practical for regular marine use.
An ultra-fast processor, GPS/WAAS receiver, C-MAP MAX/NT+ compatibility, and Guardian anti-grounding feature support route work and chart-based awareness on coastal passages. The unit also offers split-screen display, Depth Graph input, NMEA-0183 interfacing, and optional expansion into a combined charting and fishfinding system.
Key Features
- 5-inch active matrix color LCD with 240 x 320 resolution fits tighter helm layouts while keeping chart data readable.
- External GPS/WAAS receiver supports accurate vessel positioning for navigation tasks.
- Ultra-fast processor helps deliver faster chart redraw and page changes.
- Guardian anti-grounding feature checks charted hazards ahead of the vessel.
- Stores up to 500 waypoints or marks, 25 routes, and 1000 track points for routine route management.
- Depth Graph input, Tide Info, Find, GOTO, MOB, and NMEA-0183 support add useful functionality beyond basic chart display.
Applications
- Small helm stations that need a dedicated chartplotter without a large display footprint.
