PRE OWNED SKIPPER GDS-102 SKIPPER GDS-102 MARINE ECHO SOUNDER

The Skipper GDS-102 is an IMO-compliant depth sounder that features a large, 10.4-inch high-resolution color TFT LCD. Unlike standard single-channel units, the GDS-102 can interface with two separate transducers (typically 50 kHz or 200 kHz) and display both depth readings on a split screen. This dual-sensor capability is a vital safety feature for ultra-large vessels, allowing the bridge team to monitor the seabed profile at both the forward and aft sections of the hull simultaneously.

Built with the same "Danish engineering" standards as the GDS-101, this model includes a high-capacity internal memory that stores a rolling 24-hour log of depth, time, and GPS position. This digital recording system eliminates the need for mechanical paper units, ensuring the vessel stays compliant with SOLAS and IMO regulations while reducing maintenance costs. Its intuitive menu system and dedicated rotary knobs allow for rapid adjustment of gain and range in high-pressure navigational situations.

KEY FEATURES & APPLICATIONS

-- Simultaneous Dual Display: Allows for "Bow and Stern" or "Port and Starboard" depth monitoring, which is an essential requirement for many large-scale commercial ship specifications.

-- Advanced Paperless Recording: The rolling 24-hour internal memory stores all critical depth data with time/position stamps, making it easy to review historical data for port state inspections.

-- Bottom Discrimination & Hardness: Provides a clear graphical representation of the seabed, helping the navigator distinguish between soft mud, sand, and hard rock.

-- Independent Channel Control: Gain, range, and filter settings can be adjusted independently for each transducer to compensate for different hull positions and water turbulence.

-- VGA Output for Remote Monitoring: Features a standard VGA port to repeat the dual-channel display on a secondary bridge monitor or in the captain's office.

-- Draft/Trim Correction: Supports manual and automatic input of vessel draught to accurately display "Depth Below Keel" (DBK) for both sensors.

TYPICAL CONDITION (USED/REFURBISHED)

Our refurbished Skipper GDS-102 units from the Alang yards undergo a rigorous multi-stage restoration. We pay particular attention to the Dual-Channel Transceiver PCB, ensuring both channels provide stable 1kW output and high sensitivity. The 10.4-inch LCD is checked for backlight consistency and the user interface buttons are tested for mechanical reliability. We also verify the NMEA 0183 output strings for both channels to ensure seamless integration with the ship's VDR and ECDIS. Every unit is factory-reset and provided with a detailed performance report from our Bhavnagar technical facility.
