GV57 Waterproof Marine GPS Tracker - Bilge Float Switch & Theft Alert

• REAL-TIME 4G LTE GPS TRACKING FOR BOATS & MOTORCYCLES: Know exactly where your vessel or bike is at all times - live location, movement alerts, and route history right on your phone or computer. Get instant notifications if your boat is towed, tampered with, or moved without your knowledge. IP67 waterproof and built for saltwater, rain, and harsh outdoor environments.
• BILGE WATER ALERT - STOP FLOODING BEFORE IT DESTROYS YOUR BOAT: The included float switch monitors your bilge water level in real time. The moment rising water is detected, you get an instant alert - giving you time to act before flooding damages your hull, engine, or electrical systems. Includes an onboard 12V dashboard buzzer for immediate audible warning.
• LOW BATTERY & POWER LOSS ALERTS INCLUDED: Get notified the moment your onboard electrical system drops to a critical level. No more returning to a dead battery or a flooded bilge because you didn't know there was a problem. Designed for boats stored at marinas, on trailers, or left unattended for extended periods.
• GEOFENCE ZONES + THEFT PROTECTION 24/7: Set a virtual boundary around your marina slip, storage yard, or garage. If your boat or motorcycle crosses that line, you're alerted instantly. Hardwired directly to your 12V or 24V electrical system - no batteries to replace, no gaps in coverage.
• SUBSCRIPTION REQUIRED - FLEXIBLE PLANS THROUGH SPY SPOT GPS: Cellular tracking features require an active subscription. Choose between minute-by-minute live tracking or interval-based reporting to match your monitoring needs. Compatible with the Spy Spot GPS mobile app and web portal.

The GV57 Marine Safety Bundle combines real-time GPS tracking and bilge water detection into a single integrated monitoring system designed for boats operating in demanding marine environments.

This system includes a waterproof GPS tracker, float switch sensor, and dashboard-mounted buzzer that work together to help detect rising water and provide immediate alerts. When water levels increase in the bilge, the float switch activates the buzzer to notify occupants or nearby personnel of potential flooding conditions.

The integrated GPS tracking capability provides location visibility and movement alerts, helping boat owners monitor their vessel while docked, stored, or unattended. Low power consumption supports long-term storage scenarios, and the system is designed to work with standard 12V marine electrical systems commonly found on recreational and commercial vessels.

Professional installation by a qualified marine technician is recommended to ensure proper integration with your boat’s electrical system and reliable long-term performance.

This system is suitable for a wide range of vessels equipped with bilge systems, including:

• Fishing boats
• Yachts
• Sailboats
• Cruisers
• Fleet vessels

Routine maintenance such as checking battery condition, testing the float switch, and inspecting wiring connections can help maintain reliable operation over time.

GV57 Boat GPS Tracker & Bilge Alarm Installation Guide

Ensure your vessel is protected and monitored in real-time with this basic installation guide. This manual covers the core hardware wiring and initial software setup for the GV57 Marine Safety Bundle.

1. Pre-Installation Checklist

Before beginning the installation, make sure you have the following ready:

• Tools Needed: Wire strippers, electrical tape or marine-grade heat shrink tubing, zip ties, and a voltmeter.
• Power Compatibility: Verify your boat uses a standard 12V or 24V DC electrical system (the device supports an 8V to 32V DC range).
• Safety First: Disconnect your boat's main battery terminal before handling any electrical wiring.

2. Wiring Configuration Guide

The GV57 hardwired harness features color-coded wires that connect directly to your vessel's electrical and monitoring components. Follow these core connections carefully:

• Red (VCC) Constant Positive (+) Battery Terminal;
  Supplies continuous power to the tracker.
• Black (GND)Negative (-) Battery Terminal / Ground;
  Completes the electrical circuit.
• White (ACC)Ignition Switch / Keyed Power Source;
  Detects engine status (on/off tracking behavior).

Connecting the Bilge Monitor & Alarm Components:

• Float Switch Integration: Connect the designated input wires from the tracker harness to your bilge pump's submersible float switch. This allows the system to monitor water level shifts and trigger high-water alerts.
• Audible Indicator: Route the secondary output to the included 12V dashboard buzzer alarm. This ensures you receive immediate, audible on-board feedback if the bilge level rises unexpectedly.

3. Device Placement & Mounting

To ensure peak performance and reliable network communication, adhere to these placement rules:

• Orient the Face Upward: Mount the tracker securely with the front face (LED side) pointing skyward for optimal satellite visibility.
• LED Status Verification: Check the integrated face lights once power is restored:
  - Green LED: Flashing indicates an active 4G LTE cellular network connection.
  - Red LED: Solid indicates a verified GPS signal lock.
• Avoid Metal Shielding: Secure the IP67 waterproof housing using zip ties underneath the fiberglass console or dashboard. Avoid placing the device directly beneath massive metal brackets, which can block cellular and GPS reception.

4. Software Activation & Default Settings

Once the hardware is securely mounted and drawing power, finalize your system setup:

• Account Configuration: Log into your tracking mobile application or web portal to register the unique IMEI number found on your device label.
• Default Tracking Behavior: Out of the box, the GV57 is pre-configured to optimize data efficiency and power conservation:
  - When Moving: Automatically transmits location updates every 5 seconds.
  - When Stopped: Shifts into a power-saving deep sleep mode and transmits updates every 3 hours.
• Alert Customization: Set up automated text or email notifications within your app settings for critical event triggers, including low battery warnings, power disconnects, high bilge water levels, and geofence boundary crossings.
