Modern sailors rely on a broad variety of boating electronics. When searching to purchase new items, a mariner looks for a retailer that can get the products quickly, either from onsite stock or via order on the manufacturer with rapid shipment. Installation, maintenance and repair work requires a certified trade person, ideally one that can get the job done correctly and quickly the first time. Marine Electronics Juneau can deliver on all these fronts. It has a team of experienced professionals are certified, as well as fully bonded and insured.

Installing modern marine electronic products not only requires a certified professional, it requires something more. It requires a professional with a flexibility of mind that only comes with deep knowledge and long experience. It needs someone who has seen it all and then some.

Boat electrical specialists are confronted with many difficulties when sourcing, installing and repairing electronic items on boat. These difficulties recur again and again. They are a constant challenge. Here we mention a few.

Each boat, particularly older ones, has an electrical system that is virtually unique. Any person needing to work on that system must quickly develop an understanding of it. This is made difficult since the wiring may not be labeled and the overall configuration not be formally specified in technical drawings.

They need to absorb the installation details of each specific product; this is no mean feat given the enormous number of products, makes and models available on the market. There is an incredibly large number of marine electronic products including chart plotters, engine gauges, tank indicators, compasses, depth sounders, auto pilots, transducers, fish finders, anemometers, sonar, forward-looking sonar, and radar. They must also install conventional household items like dishwashers, clothes washer and dryers, stereo radio and CD players and air conditioners.

The work is always done in cramped quarters. The space for new ducting and wiring is even more restricted. This is an important factor when considering 12 volt versus 24 volt DC systems because the two require systems require different sized wiring. This can be explained as follows. We know from Ohms Law that Watts [W] equals Voltage [V] times Amps [A]. Amps is also referred to as current (or amps current) while watts is also referred to as power.

It is clear from Ohms Law that Amps equals Watts divided Volts. In other words if voltage increases, amps current decreases. This is important because the size of electrical wiring needed for a job is determined by the required current carrying capacity. The more amps current a wire has to carry, the wider diameter that wire must be for safety reasons. Decreasing voltage requires larger diameter wiring to be used. This is more expensive in terms of cost and weight on board a boat.

Marine Electronics Juneau is well familiar with all these intricacies and has successfully navigated through their challenges for many years. Members of the team are Marine Electronics Installer (MEI) certified by the National Marine Electronics Association (NMEA). Many of them have received their training or served with US Coast Guard as electronic specialists. Whatever the electronic job might be, small or big, its professionals can get it done efficiently.
