Japan Radio Company (JRC) supplies merchant fleets of the world with navigation and communications equipment. This Tokyo-based marine electronics manufacturer also makes products for pleasure boats, including fishfinders.
JRC began in 1915. In 1932, JRC created a radio transmitter for shore to ship communications. They started using microwave communication technology in 1939. JRC radar developments are used in today’s ships around the world.
With three basic fishfinder models, it’s obvious that JRC puts the company’s main emphasis into the large-ship market. Nonetheless, any of the three fishfinders created by JRC are quality examples of modern marine electronics that perform well.
High-definition, Color Liquid Crystal Display (LCD) screens are available in 6.5-inch, or 16.5-centimeter; 7-inch, or 17.8-centimeter; and 10.4-inch, or 26.4 centimeter sizes. There are 16 color shades and background colors to pick from. You can also select from a daytime or nighttime mode. Daytime visibility is extremely adequate while looking at this screen.
It goes without saying that all of the JRC marine electronics are housed in a waterproof case. Since you’re on the water, it only makes sense that precious electronics are protected from water damage.
The same software used on these smaller JRC marine electronic devices is placed on the electronics sold by JRC to the owners of large freight ships.
Complication goes out the window with JRC keys and knobs. Switching between screenshots is simple and intuitive.
One main reason for this characteristic is that JRC keeps clutter to a minimum. You get to store three types of fishing environments or species of fish. Once this data is inputted, other fishing information can be set or reset to another type by punching the “custom” button.
Many fishfinders automatically adjust the pulse width of the sound emitted by the transducer according to the depth of the water. JRC lets you decide.
You can select between long, medium and short.
Fishing enthusiasts discover quickly that by utilizing the good old fashioned manual switch, the JRC fishfinder functions far superior at detecting fish in shallow water.
Even in their baseline fishfinder, JRC allows for two frequencies to be shown on the screen simultaneously. This is a feature normally only seen in expensive fishfinders. A lower sound frequency is best for determining bottom types and usually the high frequency is paramount for shallow water fish recognition. By seeing the two frequencies together on one screen, you can best determine the size of any given fish.
A positive aspect with buying your fishfinder from a maker of ocean freighter electronics is that your new equipment is outfitted with connections to tie into more sophisticated electronics. JRC doesn’t disappoint in this regard. Peripheries include an antenna, any Global Positioning System (GPS) unit of your selection, or another video monitor. Data storage is easy on a JRC fishfinder through an SD card.
There are separate alarms for each fish, if you’re too shallow, or water is getting too deep. Also, three temperature alarms are possible, along with four alarms set according to pre-arranged navigational data. You can activate a buzzer alarm and set the timer on or off. A combination of these alarms results in safer navigation and a more efficient method of locating fish.
There aren’t too many locales in the marine world too deep to read with a JRC fishfinder. The JRC finder can operate in an automatic or manual mode and features 10 depth ranges, allowing a limit of 5,000 feet, or 1,524 meters.
Serious fishing fans agree that when you need quality marine electronics to stand up through any conditions, one of the finest fishfinders you can purchase is a JRC.
