Garmin Fishfinders For The Avid Fisherman

By Sam Perry


Do you love to go fishing? Do you enjoy it even more when you actually catch fish? Garmin has two low-priced sonar fish finders that all recreation fishermen should consider. With many of the benefits of high-end models, the Garmin 300c and 400c might just be what you're searching for to enhance your total fishing experience. Either model will allow you to find where the fish are, and discern the sizes of the fish. Although similar in many ways, there are a few slight differences between the 300c and the 400c that you should be aware of before deciding to make a purchase.

Designed to operate on both lakes and oceans, either of these models would be a great accessory for your fishing boat! The Garmin 300c is a 400-watt dual beam version and offers a wide fish-finding cone, reaching fantastic depths of 900 feet (274.32 m). The 400c gives you the choice of the dual beam or a 500-watt dual frequency transducer that lets you to reach a whopping depth of 1,500 feet (457.2 m). The dual-beam cone system has duel settings: 15 or 45 degrees emminating from the boat. The narrow beam uses a high frequency and, in turn, returns high definition results. The wide beam uses a lower frequency, allowing you to see the contours of the bottom and fish that are not directly under the craft, although they will appear at a lower definition. The dual frequency transducer, available on the 400c, can send out both high and low frequencies at at one time, so you can see both narrow and wide returns on the split display screen.

Each of these Garmin Fish-finder models has a high-resolution, 256-color display screen, that is easily readable even when in the bright sunlight. The only difference between the two is the size of the screen: a 3.5-inch on the 300c and 4-inch on the 400c, both displaying 240x300 pixels. The crystal clear color readout makes it easy to tell fish from debri. A night mode allows low-light readability and a backlit keypad makes it simple to operate at night.

Both the Garmin 300c and the 400c units offer Ultrascroll, Fish Symbol ID, A-Scope, Auto Gain and Whiteline functions. Ultrascroll is a feature that moves the sonar from side to side at a high speed giving faster updates on the display and showing fish even while you are zipping across the water to a favorite fishing hole! Fish Symbol ID helps to distinguish between different sizes of fish so you are not chasing guppies instead of salmon. A-Scope lets you to see a real-time display of fish passing through the transducer beam. Both of these fabulous sonars have an auto gain feature, which controls the sensitivity on the sonar depending upon the density of the water, or fish. Whiteline shows whether the bottom is hard or soft and allows you to distinguish different types of debris on the bottom. They also have alarms that can be set for different alerts: the presence of fish, low battery power, and shallow water - you get to set the alarm depth! Turn your alarms on and say goodbye to dead batteries and ruined propellers.

Split-screen capability lets you to take complete advantage of instant data, such as water depth, temperature and speed (for river fishing) one side and instant fish traffic on the other side. Each model has both 2x and 4x zoom capabilities for telling bottom density and/or fish size. An auto save feature for your preferred settings allows you to dial in your preferences once and they will be save when you turn off the unit. This saves having to reset your preferences during a fishing excursion that lasts more than one day.

The greatest distinction between the two units is the CANet-compatibility of the Garmin 400c. CANet is a communication system that allows integration of data between the 400c and other Garmin chart plotters such as nav systems on your boat, making the 400c a true part of your navigation system and not only a delightful sonar for fishing. One satisfied customer said, "I own a Garmin GPSMap 496 and I use it along with my 400c. The two units work together very well. Even in the middle of the ocean I can never get lost!" Another satisfied customer says, "I recently bought a Garmin Fishfinder and was very surprised to find it works right alongside my GPS."
