Queclink GV75

Queclink GV75 — Proven IP67 Waterproof 2G GPS Tracker for Motorcycles, Marine and Heavy Machinery

The Queclink GV75 is the original foundation of Queclink's GV75 waterproof tracker series — a proven, battle-tested IP67 device built for vehicle tracking applications in the harshest environments. Where standard fleet trackers are designed for the controlled environment of a car or van interior, the GV75 is designed for the elements — motorcycles, watercraft, marine vessels, quad bikes, agricultural machinery and heavy equipment that operate outdoors in rain, mud, saltwater and extreme temperatures.

With multiple I/O interfaces including an RS232 serial port and digital I/O, the GV75 goes well beyond basic GPS location — supporting temperature monitoring via external sensors, driver identification, remote immobilisation and Garmin navigation integration. Its 1,100mAh Li-Polymer backup battery provides extended standby time and tamper protection if vehicle power is interrupted, and a 3-axis accelerometer enables sophisticated motion detection, driving behaviour monitoring and power management.

As an authorised Queclink distributor in the UK, Tracking Hardware UK ships the GV75 directly from our London warehouse — with trade pricing available for telematics service providers, fleet operators and resellers.

Key Features

• IP67 waterproof and dustproof — fully sealed enclosure rated to IP67, withstanding complete temporary immersion — purpose-built for motorcycles, watercraft, marine vessels, quad bikes and outdoor machinery in all weather conditions

• 2G GSM/GPRS quad-band — established 2G connectivity supporting 850/900/1800/1900 MHz for real-time and periodic tracking across UK and international networks

• RS232 serial port — connects to external accessories including Garmin FMI navigation devices, temperature sensors, RFID readers and fuel level monitors via the 8-wire cable

• Digital I/O — configurable digital inputs and outputs for ignition detection, door sensors, remote immobilisation and accessory control

• Temperature monitoring — RS232 interface supports connection of temperature sensors for cold chain, refrigerated transport and environmental monitoring

• Driver identification — supports driver identification via wired accessories including iButton readers (via RS232-to-1-Wire accessory) and RS232 RFID readers for fleet accountability

• 3-axis accelerometer — detects motion, impact and orientation for crash detection, driving behaviour monitoring and intelligent battery management

• 1,100mAh Li-Polymer backup battery — large backup battery providing extended standby time and maintaining device operation if vehicle power is interrupted

• Crash detection and accident data collection — captures pre and post-impact data for accident reconstruction and insurance evidence

• Driving behaviour monitoring — tracks harsh braking, acceleration and cornering for driver safety scoring

• Tow and motion detection — triggers alerts if the vehicle is moved without ignition

• Geofencing — configurable zone alerts when vehicles enter or exit defined areas

• Up to 10,000 buffer messages — stores data locally when out of coverage and transmits on reconnection

• Under 2.5m GNSS accuracy — u-blox All-in-One GNSS receiver for precise real-time positioning

• OTA control — remote firmware and configuration management

Driver Identification Options for the GV75

The GV75 has no Bluetooth interface, so it is not compatible with our BLE driver identification keypad. It does support driver identification through its wired interfaces — an iButton reader connected via Queclink's RS232-to-1-Wire accessory, or an RFID reader via the RS232 serial port. Driver IDs are logged alongside all GPS and telematics data, providing accountability across motorcycle fleets, marine operations and heavy machinery. If you want BLE keypad support in the same waterproof format, choose the GV75CG. Contact us to discuss the right reader and GV75 bundle for your fleet.

GV75 vs GV75CG vs GV75MG — Which Should You Choose?

The GV75 family covers three network generations. The GV75 uses 2G GSM — suitable for cost-sensitive deployments in areas with reliable 2G coverage and a shorter deployment horizon. The GV75CG upgrades to LTE Cat 1 for faster data on modern 4G networks with a wider 9-90V power input — the recommended choice for most new UK and European deployments. The GV75MG uses LTE Cat M1 and NB1 for broader global IoT coverage — best suited for international deployments across multiple countries.
