Garmin Chartplotter & Fish Finder Guide Australia (2026)
If you’re researching a Garmin chartplotter fishfinder setup, you’re not alone. Garmin marine electronics are some of the most searched systems in Australia — and for good reason. Clean interface, powerful sonar options and seamless integration across radar, autopilot and LiveScope.
At Shotgun Marine, we supply and install Garmin chartplotters and fish finder GPS systems Australia-wide. As authorised multi-brand dealers, we don’t push one brand for commission — we recommend what suits your boat and how you fish.
What Is a Garmin Chartplotter Fishfinder?
A Garmin chartplotter fishfinder combines GPS mapping and sonar into one system. You get detailed marine charts plus real-time depth, structure and fish targets displayed on the same screen.
Most modern Garmin units include:
- Built-in CHIRP sonar
- High-resolution touchscreen displays
- Network capability via NMEA 2000
- Radar integration
- LiveScope compatibility
Popular Garmin Chartplotter Models in Australia
Garmin GPSMAP Series
The Garmin GPSMAP range is one of the most popular chartplotter fishfinder systems in Australia. Models like the 8610xsv and 8416xsv are commonly fitted to serious offshore fishing boats.
They support:
- 1kW and 2kW transducers
- Garmin LiveScope Plus
- GMR Fantom radar
- Autopilot integration
Garmin ECHOMAP Series
For smaller trailer boats and inshore fishing, the ECHOMAP range provides excellent fish finder GPS performance at a more accessible price point.
Garmin CHIRP vs LiveScope – What’s the Difference?
CHIRP sonar provides traditional depth sounding and structure mapping beneath the boat. It’s ideal for reef fishing, offshore snapper and general bottom work.
LiveScope shows real-time movement — fish swimming, structure ahead of the boat and lure presentation. It’s a tactical advantage for shallow water and active fishing.
Many serious anglers run both systems for maximum versatility.
Choosing the Right Garmin Sounder Setup
The biggest mistake we see isn’t the screen choice — it’s transducer selection and installation. A powerful Garmin chartplotter won’t perform properly if the transducer is undersized or poorly mounted.
- 600W – Inshore & estuary fishing
- 1kW – Offshore reef & snapper
- 2kW – Deep drop & game fishing
Correct mounting position is critical if you want to hold bottom at speed offshore.
