Skipper GDS101 Echosounder is a marine echo sounder designed to provide continuous depth information for vessels. The device displays echo sounder graphics on a color LCD screen, while also displaying relevant navigation data to assist marine officers in monitoring the depth below the hull during voyages, docking/undocking, or navigating in shallow waters.

series offers configurations for different needs. According to product information,GDS101 system is suitable for commercial vessels, cargo ships, passenger ships, service vessels, offshore vessels, professional fishing vessels, and any vessel requiring echo sounder equipment that meets IMO requirements. According to product information, the SKIPPER GDS101 meets or exceeds IMO requirements and is available with multiple standard interfaces, including NMEA 0183 input/output.

SKIPPER GDS101series offers configurations for different needs. According to product information,10.4 inch LCD color display uses a

10.4-inch LCD color display

with day/night display modes and adjustable backlight. The echo sounder graphics are displayed continuously, making it easy for operators to observe changes in depth and seabed topography as the vessel moves.

GDS10124-Hour History Memoryseries offers configurations for different needs. According to product information,GDS101

has a history memory that continuously stores depth data, time, and available navigation data for the

past 24 hours

Skipper GDS101 is a single-channel echo sounder, with standard transducer connections for resonant frequencies38 kHz, 50 kHz, and 200 kHz. According to product documentation, only one transducer/frequency is displayed at a time and the user selects the corresponding transducer in the menu.

Different frequencies are suitable for different operational requirements:

NMEA 0183 input/output connection

GDS101 supports communication NMEA 0183 input/output, allowing data exchange with other maritime systems. NMEA input can receive navigation data, while output can supply depth data to external devices such as VDR, ECDIS, repeaters, monitoring systems, or integrated bridge equipment.

Thanks to its standard connectivity, the GDS101 is easily integrated into various vessel configurations, from simple systems to multi-receiver bridge systems.

External printer, VGA and peripheral device connections

According to the product description, SKIPPER GDS101 has external connection ports forprinter, NMEA input/outputand in appropriate configurations. These technologies help improve the quality of positioning data when the operating area has corresponding augmented signal support.NMEA input/output. The external printer allows printing of current data or historical data stored in memory, serving for shift logs or technical inspections.

Some documents also state that the GDS101 can connect to an external standard printer and supports standard interfaces for marine echo sounder systems.

Depth Alarm Function

Skipper GDS101 is equipped with alarm functions, including shallow and deep depth alarms depending on the configured settings. The device can also connect to external alarm systems, increasing awareness when the vessel enters areas with unsafe depths.

The alarm function is crucial when the vessel sails near shore, enters ports, passes through shallow channels, or anchors in areas with tidal changes.

Complies with IMO and Wheelmark certification

SKIPPER GDS101 is described as meeting or exceeding IMO requirements, and also hasIMO Wheelmark certification. This is an important factor for vessels requiring marine echo sounder equipment that meets international standard requirements.

Some sources currently classifySkipper GDS101 in the product groupDesigned for fast installation, low cost, and ease of use., so when purchasing replacements or for maintenance, it is necessary to clearly check the condition of the goods, component availability, certifications, and corresponding replacement plans.

Why choose Skipper GDS101 Echosounder?

SKIPPER GDS101is the right choice for vessels needing a marine echo sounder system with a large screen, clear interface, NMEA 0183 support, alarm functions, and 24-hour historical memory. The device can connect to an external printer to print current or saved data, and supports multiple 38/50/200 kHz transducer options to meet the requirements of each vessel type.

For ship owners, ship management companies, and marine electronics service providers, the GDS101 is suitable for replacing, maintaining, or upgrading existing SKIPPER echo sounder systems on board, especially for systems requiring IMO Wheelmark certification and standard data communication.

Notes when ordering the Skipper GDS101

Before ordering or replacing the Skipper GDS101 Echosounder , it is advisable to clearly check:

• Is the package a complete system or just the operator unit.
• Does it come with a transducer (38 kHz, 50 kHz, or 200 kHz).
• Is the current transducer on board compatible with the GDS101.
• Does the system require a single frequency or a multi-transducer configuration for menu selection.
• Is an external printer needed for historical data printing.
• Is a VGA connection to an external monitor required.
• How the receiving device needs NMEA 0183 input/output.
• Are IMO Wheelmark, DNV/MED certifications, or classification society documentation required.
• The GDS101 may be a discontinued model in some markets, so stock status and spare parts availability should be checked.
• After installation, check offset, depth alarms, NMEA output, data history, and transducer signal quality.
