GPS 73 - Portable marine GPS

The GPS 73 measures 6.6 cm in width, 15.2 cm in height, and 3.0 cm in thickness. Its weight is 203.1 grams with batteries.

The GPS 73 offers up to 18 hours of battery life with AA batteries, making it suitable for extended outings.

The GPS 73 operates on two AA batteries (not included). For best performance, use NiMH or lithium batteries, especially in cold weather.

No, the GPS 73 is equipped with a 4-level grayscale backlit LCD screen. It has a 6.6 cm diagonal and a resolution of 128 x 160 pixels, ensuring clear readability of information.

Yes, the GPS 73 has an IPX7 waterproof rating. This means it is resistant to accidental immersion up to 1 meter deep for 30 minutes.

Yes, the GPS 73 is designed to float, which is an advantage in case of accidental immersion.

The GPS 73 provides several essential navigation functions:

Waypoints: Creation, projection, navigation, editing, deletion, and refining of position (averaging). Routes: Creation, editing, map display, deletion, navigation, and route reversal. Tracks: Recording, display, saving, erasing, and track navigation. Main pages: Chart, Compass, and Dashboard.

The GPS 73 allows you to manage waypoints in several ways:

Creation: Saving your current position.Projection: Creating a new waypoint from an existing one with a distance and bearing.Navigation: Guidance to a saved waypoint.Editing: Modifying the details of a waypoint.Deletion: Removing a waypoint.Averaging: Improving waypoint accuracy by taking multiple measurements.

Yes, the GPS 73 integrates a high-sensitivity GPS receiver compatible with WAAS (Wide Area Augmentation System), enabling fast signal acquisition and precise position holding.

The GPS 73 provides an RMS accuracy of less than 15 meters. With WAAS compatibility, differential accuracy improves to less than 3 meters.

Yes, the GPS 73 has a "Sail Racing" mode that helps cross the starting line of a regatta at the precise moment the race begins. It allows you to synchronize a countdown and indicates whether your sailboat will cross the line early, late, or exactly on time. You can also define the starting line by marking the port and starboard buoys or by entering their coordinates.

Yes, the GPS 73 can be used for land navigation via its "Highway" mode.

The Instruments page displays data such as wind speed, temperature, and wind direction. This information is provided by sensors connected to the device via an NMEA 0183 network.

To install the batteries:

Slide the battery compartment cover downward and remove it from the rear of the device. Insert two AA batteries, observing the correct polarity. Replace the battery compartment cover.

To power on the GPS 73, press and hold the power button (the button with the bulb symbol).

After installing the batteries, you can select the battery type in the settings:

Hold the power button down. Select Setup > System > Battery Type. Choose the option matching the battery type you are using (e.g., alkaline, NiMH, lithium).

Yes, the GPS 73 has a power/NMEA 0183 connector, allowing it to receive data from connected instruments over an NMEA 0183 network, such as speed or wind direction sensors, to display on the Instruments page.

The GPS 73 features a 128 x 160 pixel monochrome LCD screen that displays a basic chart with your position, waypoints, and tracks. However, this unit is not designed to show detailed marine charts or complex vector charts. It is primarily a standalone navigation and guidance tool.
