Marine Electronics Sales & Installation Charleston SC

 

Modern marine electronics should make your boat easier to operate, safer to navigate and more enjoyable to use. Charleston Marine sells, installs and integrates marine electronics and electrical accessories for boats throughout Charleston and the South Carolina Lowcountry.

Whether you are replacing an outdated chartplotter, adding sonar, building a complete electronics package, upgrading your stereo, installing thermal or night-vision equipment, or improving your boat’s battery and charging system, our team can design and install a system around the way you actually use your boat.

We are dealers for Garmin, Simrad, Raymarine, SIONYX, JL Audio, Power-Pole, Stealth Chargers, Ionic Lithium, Impulse Lithium, FLIR, Battery Tender and Interstate Batteries.

Complete Marine Electronics Packages

 

A good electronics installation is more than mounting a display on the dash. The equipment needs to work together, receive clean reliable power and be installed where it is easy to see and operate.

Charleston Marine can help design and install complete electronics systems including:

• GPS chartplotters and multifunction displays

• Sonar and fish finders

• Traditional, CHIRP and scanning sonar

• Radar systems

• Autopilot

• VHF radios

• AIS equipment

• Engine-data integration

• NMEA 2000 networks

• Transducers

• Marine cameras

• Night vision and thermal imaging

• Stereo systems, amplifiers and speakers

• Battery monitoring and charging systems

• Lithium battery systems

• Power distribution and accessory integration​

​​​Garmin, Simrad & Raymarine Electronics

 

Choosing the right display is only part of building a good system. Screen size, sonar capability, transducer selection, radar, networking and engine integration all need to match the boat and how it is used.

We install and integrate systems from Garmin, Simrad and Raymarine, including single-display upgrades and complete multi-display helm packages.

If you are starting with a blank dash, we can help plan the entire system. If you already have electronics onboard, we can evaluate what can be retained and what should be upgraded.

​

Sonar & Transducer Installation

 

The performance of even the best sonar system depends heavily on the transducer and installation.

Charleston Marine can help select and install the proper transducer for your hull, electronics and fishing style, including:

• Transom-mount transducers

• Through-hull transducers

• CHIRP sonar

• Side and down scanning systems

• Structure imaging

• Offshore and deep-water sonar applications

• Networked sonar systems

Proper location, mounting and setup can make the difference between an expensive screen that produces mediocre information and a system that actually performs the way it was designed to.

​

Radar, Autopilot & Navigation Systems

 

For offshore and coastal boating, properly integrated navigation equipment can significantly improve situational awareness and ease of operation.

We install and integrate:

• Marine radar

• Autopilot systems

• Heading sensors

• GPS antennas

• AIS

• VHF radios

• NMEA 2000 networking

• Engine and fuel data

• Navigation displays

Our goal is to make the system work as one package instead of a collection of unrelated components mounted around the helm.

​

FLIR & SIONYX Night-Vision Systems

 

Night operation requires more than simply having a good chartplotter.

Charleston Marine installs FLIR thermal imaging and SIONYX digital night-vision systems for boaters who operate before sunrise, after dark or offshore in limited visibility.

These systems can provide another layer of situational awareness when identifying boats, markers, docks and other objects that may be difficult to see with the naked eye.

​

 

 

 

JL Audio Marine Stereo Systems

 

A good marine audio system should sound good at idle, underway and while the boat is sitting at the sandbar without becoming an electrical nightmare behind the console.

Charleston Marine installs JL Audio marine speakers, amplifiers, subwoofers and source units, along with the wiring, circuit protection and power distribution needed to support them properly.

We can upgrade an existing stereo or design a complete audio system around the boat.

​

Lithium Batteries, Charging & Power Management

 

Modern electronics, audio systems and trolling motors can place substantial demands on a boat’s electrical system.

We sell and install equipment from Ionic Lithium, Impulse Lithium, Stealth Chargers, Battery Tender and Interstate Batteries and can evaluate the complete battery and charging system before adding additional electrical loads.

Services can include:

• Lithium battery upgrades

• Starting batteries

• House battery banks

• Dedicated electronics batteries

• Trolling-motor battery systems

• Onboard chargers

• Alternator charging systems

• Battery switches

• Automatic charging relays

• Battery monitoring

• High-amperage cabling

• Circuit protection

The objective is not simply to add more batteries. It is to build a system that charges correctly, distributes power safely and supports the equipment you expect to use.

​

 

 

 

Power-Pole Equipment & Integration

 

Charleston Marine also sells and installs Power-Pole marine products, including equipment that can be integrated with compatible electronics and electrical systems.

When multiple systems are being added at the same time, planning them together allows us to address power requirements, wiring, networking and control locations before installation begins.

​

Clean Installation Matters

 

The most expensive electronics available will not perform reliably if the installation behind the dash is poorly executed.

We pay attention to what you cannot see just as much as what you can.

That means proper wire sizing, marine-grade connections, circuit protection, secure routing, network organization and equipment accessibility for future service. Displays should look factory installed from the helm, and the wiring behind them should look like someone planned it.

​

Upgrading an Existing Boat

 

You do not need a new boat to have modern electronics.

Many older boats are excellent candidates for upgrades, but installing new technology on an existing electrical system sometimes exposes problems that have accumulated over years of modifications.

Before a major electronics installation, Charleston Marine can evaluate the boat’s existing:

• Battery capacity

• Charging system

• Electrical distribution

• Wiring

• Grounds

• Available dash space

• Network architecture

• Existing transducers and sensors

If something should be corrected before installing thousands of dollars of new equipment, we would rather identify it first.

Whether you need a single chartplotter installed or a complete helm redesigned with navigation, sonar, radar, audio, batteries and integrated boat systems, Charleston Marine can help design and install the package.
