If you want to catch a lot of fish, the first step is finding out where they're hiding. A portable fishfinder makes it easier to hook the next big one.
Before you buy a fishfinder or depth finder, you'll want to consider the different types of features that best meet your needs, including frequencies, wattage and display specifications. Higher frequencies work best in shallow water, where they provide detailed resolution and less background noise on the screen. Lower frequencies are the best choice for fishing in deeper water, where you'll need a broader range.
The power of your fishfinder is represented in watts. If you're fishing in shallow water, a lower wattage will be enough to meet your needs. For deeper water, you'll need higher watts.
For screen resolution, a higher pixel count provides clearer details and a better representation of what's below your boat. A larger screen size allows you to see more information on a split screen. You can choose between a black-and-white or color display.
