How would you enjoy it if everytime you went fishing you really caught fish? You should consider a couple of Garmin’s sonar fishfinder. The Garmin 300c and the 400c is considered to be the favorite to ensure your success. There will be no more wishing you knew as to where or what size your fish might be ever again. Before you purchase one or the other, you should probably know about some of the differences of the two units.

It doesn’t matter if your craft is a deep sea trawler or a fresh water pontoon boat, either model will work for you! The Garmin 300c offers a 400-watt wide cone system that works by sending out two beams and can reach incredible depths of 900 feet. The Garmin 400c gives you this system and/or a 500 watt dual frequency transducer that can reach a staggering 1500 feet. obviously the 400c would work fantastic in the middle of the Pacific Ocean. Both units can be set to emit sonar beams at 45 degrees from the bottom of your boat allowing to see objects even if they are not right under you giving you a fantastic picture of what is below.

The 300c sports a 3.5 inch diagonal screen and the 400c is 4.0 inch display screen. Both units are designed to be readable even in bright sunlight. They both have a high-quality 256-color display screen. Both units have a back lighting feature behind the keypad and they also have a night mode for dark conditions.

If you enjoy fishing in lakes, rivers, along a shoreline, or in coves then you know what I am talking about when I say damaged propellers. Both models have alarms that are completely programmable. You can program these alarms for water depths, also for the presence of fish, for low batteries and a whole bunch of other things. A awesome feature of both models is Fish Symbol ID. This helps you to discern different fish from each other. Whiteline is something that will help you to tell if the bottom of the ocean is actually dirt or sturgeon. Ultrascroll helps to see fish in real-time even while zipping at high speeds across the water.

A fantastic new update to the Garmin Fishfinder is an autosave feature. The older units wouldn’t save all of your settings once the unit was shut down for the day. Another fantastic feature is a spit screen function with both models. This will let you to monitor water temprature, and depth along with other useful data. On the other side of the display screen you can view instant information on fish traffic and the contours of the ocean bottom. This will help identify sunken boats and other natural fish habitats. One more bonus of the split screen is a zoom.

Do you know about CANet? CANet is a communication protocol that will let other chart plotters like navigation systems share information with the Garmin 400c. This means your 400c can be truly integrated with a navigation system and it now becomes a top of the line system, not just a top notch fishfinder. What I have discovered from my research is the difference from these two Garmin fishfinders and the competition is that the other models are indeed sonars for fishing and the Garmin models are packed full of cutting edge technology with the features of units that costs thousands of dollars. If you are ok with just hunting for fish the Garmin 300c and Garmin 400c are probably not for you, however if you want to fish like the pro’s, look again at Garmin.
