The 7" SNS-700EF is packed with features and provides boaters with important C-MAP MAX charting capabilities like programmable anti-grounding, flashing navaids and aerial imagery, along with dual-frequency fishfinding and color radar (when matched with optional SI-TEX MDS-1, MDS-8 or MDS-9 Radar Scanners). The system also provides the latest AIS integration software, allowing for simple integration with SI-TEX Metadata AIS Black Box modules and practical, easy-to-use AIS chart overlay functions. The unit can easily navigate in Loran TD mode - a big advantage for serious anglers who have their fishing spots saved this way.
