About the Garmin GPSMAP 8412xsv
The GPSMAP 8412xsv is part of Garmin’s premium 8400-series chartplotter range. It gives boat owners a high-quality 12" touchscreen display for navigation, sonar, charting and full helm integration.
Where the 8416xsv suits larger helm stations and flybridge setups, the 8412xsv is ideal for boats that need a serious Garmin system in a more compact footprint.
12" sunlight-readable touchscreen display
Built-in 1 kW Dual-Channel CHIRP traditional sonar support
Built-in ClearVü and SideVü scanning sonar support with compatible transducers
Compatible with Garmin Vision+ charting
NMEA 2000 and Garmin Marine Network integration
Supports radar, autopilot, instruments, VHF and engine data integration
Multi-display capable when connected into a Garmin marine network
Supports compatible Garmin live sonar options as add-ons
The 8412xsv is commonly installed as the primary helm display on offshore fishing boats, centre consoles, cruisers and larger trailer boats. When matched with the right transducer, radar, autopilot or NMEA 2000 network, it becomes the centre of a fully integrated marine electronics system.
Why Shotgun Marine
We are authorised Garmin dealers and marine electronics service specialists with 25+ years of hands-on installation experience.
Every package we sell is backed by real technical knowledge - not just an online checkout and a box on your doorstep.
We supply, install, configure and support the complete system so it works properly on your boat from day one.
Correct Mounting for a 12" Display
A 12" chartplotter is a great size for many offshore boats, centre consoles and cruiser helms, but the mounting still needs to be right.
Our technicians assess the dash space, visibility, cable access and mounting method before installation.
We can install the GPSMAP 8412xsv as a flush mount, bracket mount or surface-mounted display depending on your vessel and helm layout.
TM275LHW CHIRP Transducer Setup
The TM275LHW is a serious 1 kW CHIRP transducer suited to offshore fishing and deeper-water performance.
Correct transducer placement is critical, especially on planing hulls, so we assess the hull shape, water flow, trailer position and cable route before fitting.
A good sounder is only as good as the install. We make sure the transducer is positioned, cabled and configured correctly for your boat.
NMEA 2000 Network Setup
We configure the full NMEA 2000 network during installation so compatible devices can communicate properly.
This may include engine data, autopilot, VHF, heading sensors, fuel data, instruments and other onboard systems.
Done right, your Garmin system becomes one connected helm - not a bunch of separate screens and cables fighting each other.
Full Commissioning
After installation, we check the system, configure the sonar, confirm chart setup, test the network and verify operation on the water where required.
You leave with the confidence that your display, transducer, charts and network are set up properly for your vessel.

Frequently Asked Questions
Does this package include installation?
No. This package is designed as a professional supply only package. Final installation costs vary depending on your boat, helm layout, transducer position, cable access and network setup. We quote and confirm everything before booking the job.
Will a 12" chartplotter fit my helm?
A 12" display suits many offshore boats, centre consoles, cruisers and larger trailer boats, but it still depends on your dash space and mounting options.
We assess whether flush mount, bracket mount or surface mount is the best fit for your vessel.
Is the GPSMAP 8412xsv good for offshore fishing?
Yes. When matched with the right transducer, the GPSMAP 8412xsv is a strong option for offshore fishing.
The TM275LHW gives serious CHIRP sonar performance for depth, bottom detail and fish-target separation.
What does the TM275LHW transducer do?
The TM275LHW is a 1 kW wide-beam CHIRP transom mount transducer. It provides depth and water temperature, with low and high-frequency CHIRP performance suited to offshore fishing and fishfinding.
Does the GPSMAP 8412xsv support ClearVü and SideVü?
Yes, the GPSMAP 8412xsv has built-in support for ClearVü and SideVü scanning sonar when paired with compatible scanning sonar transducers. The TM275LHW is a CHIRP transducer, so if you want scanning sonar as well, we can advise the correct additional transducer setup.
Can I connect radar, autopilot or another display later?
Yes. The GPSMAP 8412xsv supports Garmin marine networking and NMEA 2000 integration, so it can form the centre of a larger Garmin system.
Radar, autopilot, VHF, instruments and additional displays can be added depending on your vessel setup.
Do I need Garmin Vision+ charts?
For most coastal and offshore boating, detailed charts are highly recommended. Garmin Vision+ gives premium charting features for supported regions and helps improve route planning, navigation and situational awareness.
What warranty is included?
Garmin products include Garmin manufacturer warranty. As an authorised Garmin dealer and service agent, Shotgun Marine can help with warranty support, service advice and system troubleshooting directly.
