Garmin GPS Chartplotters
Garmin GPS Chartplotters – Professional Installation & Service | NSW
Garmin GPS chartplotters are widely used across Australia for their intuitive operation, strong charting ecosystem and reliable performance on both recreational and commercial vessels. At Shotgun Marine Services (SMS) and PMMS, we specialise in Garmin GPS chartplotter installation, system integration and ongoing support, delivered through a consultation-led approach — not a retail checkout.
Based in Port Macquarie and servicing the Mid North Coast NSW and New South Wales, our expert marine electronics technicians assess your vessel, helm layout and operating requirements before specifying the right Garmin chartplotter solution. This ensures the system is installed correctly, integrated cleanly, and supported long after handover.
Diagnosis-Led Garmin Chartplotter Solutions
Garmin chartplotters are powerful tools, but performance depends heavily on correct specification, installation and commissioning. Screen size, mounting position, power quality, transducer pairing and network integration all affect how the system performs on the water.
Our approach is to assess and diagnose first, then design a Garmin chartplotter setup that suits how the vessel is actually used — whether that’s coastal cruising, offshore fishing or commercial operation.

Garmin Chartplotters for Recreational & Commercial Vessels
We install and support Garmin GPS chartplotters on a wide range of vessels, including:
- Offshore and coastal recreational boats
- Game fishing and tournament vessels
- Charter boats and professional operators
- Commercial and working vessels
Whether you’re upgrading an older unit or planning a full electronics refit, we focus on reliability, usability and long-term support, not just the hardware itself.
Integrated Garmin Navigation Systems
Garmin GPS chartplotters are often part of a broader onboard system. Our technicians ensure Garmin units are integrated correctly with:
- Autopilot and steering systems
- Radar and AIS
- Sounders and transducers
- Engine data and vessel monitoring
- Existing marine electronics networks
Correct integration improves situational awareness, reduces operator workload, and delivers a cleaner, more reliable system overall.
Why Choose Shotgun Marine for Garmin Installation
Boat owners and operators choose SMS and PMMS for Garmin chartplotter work because we:
- Operate as marine electronics specialists, not an online shop
- Prioritise technical consultation and diagnosis
- Deliver clean, professional installations
- Support large electronic fitouts and complex systems
- Provide long-term servicing, updates and troubleshooting
Add-to-cart functionality is intentionally disabled so we can focus on properly specified Garmin systems, not time-wasting enquiries.
