How to Use a Portable Fish Finder

Fish finders are one of the most valuable and resourceful tools that you have in your fishing arsenal. Once you have purchased a portable fish finder, the next step is getting out on the water and putting it to use. Portable fish finders are generally rather easy to operate and extremely efficient. Your owner's manual is full of vital information and operational capabilities, so you should refer to your manual first and foremost. Here are some basic tips on how to operate your fish finder.

1. First: Power supply

   Once you find out what type of batteries your unit requires, it is advisable that you purchase rechargeable batteries. Even if your batteries possess a long battery life, you are likely going to need to recharge the batteries after several fishing trips. Using rechargeable batteries lowers your expenses over the long run.

2. Second: Mounting

   Most portable fish finders are equipped with a suction-cup mounting system, making them easy to mount nearly anywhere on your boat. The transducer is good when mounted anywhere on your boat, as long as it is secure and underwater, so the sonar functions properly. Avoid placing your transducer near the motor, as it may interfere with your readings.

3. Third: Display

   Place your display screen in a highly visible area that is easy to get to. Pay particular attention to the water depth; most portable fish finders are not as effective at great depths as they are in shallower water. Temperature and structures also matter, so stay alert for drop-offs, weed beds, fallen logs and rocks. These are areas where fish are often abundant. Locate where the fish are, and cast away.
