The NavPro 900 and 1200 MFDs offer optional high-resolution WI-FI radar that makes it easy to install and rig SI-TEX’s 4kW, 24-inch compact radome on just about any vessel. By mounting and wirelessly syncing the SI-TEX MDS-12 Network Radome to a NavPro unit, boaters can turn these popular and affordable MFDs into powerful 36-nm range radars that deliver excellent target resolution and a range of features boaters expect from professional-grade SI-TEX radars.   Overlaying  radar targets onto the feature-rich Polaris Charts provides navigators with enhanced situational awareness and safety, even in the most challenging conditions.

In addition to the included Polaris Charts, SI-TEX’s NavPro Series is also compatible with optional Navionics Platinum+ cartography.
