Electronic Navigation Console ENC3‐PRO

Seacraft ENC3-PRO Electronic Navigation Console

The ENC3-PRO is a civil and scientific version of Seacraft's military-grade underwater navigation console. It provides multi-waypoint navigation, underwater dead-reckoning position calculation, and optional GPS recalibration via an external miniature GPS receiver mounted on a buoy or connected directly by cable. The unit can be used mounted on a diver propulsion vehicle (DPV), with a surveyor tool, or as a standalone console.

How it works

• Underwater navigation uses dead-reckoning to calculate position when GPS is unavailable.
• When a GPS fix is acquired (via a surface float or short-mounted module), the ENC3-PRO recalibrates the current position and continues navigation from that fixed point.
• Divers can select and navigate to any pre-programmed waypoint at any time during the dive.

Modularity and GPS options

• Supports a miniature GPS (Type B) that can be connected directly with a 0.1 m cable or with 3 m or 10 m cables and a buoyancy float for surface reception without surfacing the diver.
• Cable lengths are quick-change and require no tools; longer cables can be wound on dedicated holders attached to a DPV.
• Can be installed on scooters or used independently depending on mission needs.

Route planning and data

• Free PC software for planning routes and programming up to 29 waypoints; points may be entered as GPS coordinates or azimuth/distance and can include short text descriptions.
• Logged tracks can be reviewed after dives and exported in multiple formats (e.g., KML for Google Earth, GIS formats, or CSV).
• All obtained GPS positions are stored in device memory for survey and archaeological applications.
