Service areas / Middle Keys

Marine electronics in Marathon

The heart of the Middle Keys, covered with dockside service runs from our Key Largo location.

Local waters

Our technicians serve Marathon dockside, including:

Cruisers, liveaboards, and offshore boats staging for the Gulf Stream. Navigation refits, autopilots, power monitoring, and communications.

Sales & System Design: Every major brand in stock, and a sales team that designs complete, integrated systems, not just line items.
Installation: Factory-trained installers with experience on everything from center consoles to 160-foot motor yachts.
Service & Repair: Factory-certified in-house repair for the brands we sell, backed by a two-year warranty on all of our labor.
Sea Trials & Training: Every installation ends with a sea trial and onboard instruction, so the system is proven underway before we hand it over.

Tell us about your boat and what you need. We will quote the complete job and schedule the crew at your dock.
