Portable Fish Finder<\/span><\/p>\n

A portable fish finder is a small device that uses sonar technology to detect things beneath the surface. It is great at detecting all kinds of fish, both small and large ones.<\/span><\/p>\n

The best thing about these gadgets is that they don\u2019t need to be mounted on a boat to work.<\/span><\/p>\n

Traditional fish scanners need to be hardwired to a boat. With these, you can fish from the shore without having to worry about logistics.<\/span><\/p>\n

As you can imagine, they\u2019re pretty lightweight. The smallest ones fit in your pocket and pair up with your phone. But even the biggest models are compact enough to fit inside a small backpack.<\/span><\/p>\n

How Does a Portable Fish Finder Work?<\/span><\/strong><\/p>\n

Portable fish finders use sonar technology, like many other gadgets. The transducer emits sound waves. If there\u2019s an object in their way, the waves will hit it and bounce back.<\/span><\/p>\n

When those waves reach the transducer, the software calculates how far away the object is. It does this by analyzing how many seconds it took for the waves to bounce back from the obstacle.<\/span><\/p>\n

On the screen, you\u2019ll see how deep the fish are based on the readings the transducer made. If there are quite a lot of obstacles in the way of the device, you can pretty much deduce it\u2019s a good spot for fishing.<\/span><\/p>\n

Do Portable Fish Finders Work?<\/span><\/strong><\/p>\n

Yes, they do! The higher-end models can detect small fish with a lot of precision.<\/span><\/p>\n

They can also tell a rock or bank of sand from a school of fish, so you\u2019re never induced into error.<\/span><\/p>\n

The cheaper models will still accurately tell you where fish are. Yet, they\u2019re not as sensitive as other items and will only be able to detect medium-sized fish (larger than 4 inches).<\/span><\/p>\n

Who Should Get a Fish Finder?<\/span><\/strong><\/p>\n

Fishing fans can benefit a lot from getting one of these devices. For starters, fish finders lead you to good fishing spots.<\/span><\/p>\n

Pick an area of the lake or shore that\u2019s home to a larger number of fish. No more waiting for hours for something to bite.<\/span><\/p>\n

How to Pick the Best Portable Fish Finder<\/span><\/strong><\/p>\n

A portable fish finder can be a helpful tool whether you like to fish below the ice, with a jig, from a boat, or the shore. The new wireless fish finders can be taken anywhere.<\/span><\/p>\n

A fish finder is an easy way to help your fishing game, even if fishing is a hobby rather than a lifestyle.<\/span><\/p>\n

These features tell you a lot about each portable fish finder.<\/span><\/p>\n

Wireless – Traditional portable fish finders wire into an existing electrical system and draw power from your boat to operate.<\/span><\/p>\n

Wired fish finders tend to be cheaper, but wireless models are more portable and convenient.<\/span><\/p>\n

Some use AAA batteries, while others are rechargeable. If you like to fish by kayak or on the shore, a wireless fish finder is the best option, since you don\u2019t have to plug it into anything.<\/span><\/p>\n

Built-In GPS – A GPS fishfinder combo allows you to map and keep track of good fishing spots and ones to avoid.<\/span><\/p>\n

The best GPS fishfinder models combine satellite data with other mapping methods so you can easily find areas that are clear of tangling weeds and debris and full of fish again and again.<\/span><\/p>\n

If you want to be able to find the same jackpot area on your next trip, a handheld fishfinder with GPS is a good choice.<\/span><\/p>\n

Maximum Depth – Most fish finders can measure depths of up to 100 meters, or about 328 feet.<\/span><\/p>\n

Depth may not be as much of an issue for you if you tend to fish in shallow waters, but if you fish in deep lakes and rivers, having a maximum depth of 100 meters or more can be crucial to finding your next big catch.<\/span><\/p>\n

Color LCD – A color LCD display is a great feature for mapping debris and bottom composition, as well as potential fish.<\/span><\/p>\n

Most of the simplest and cheapest fish finders have a black and white LCD screen and don\u2019t provide as much information.<\/span><\/p>\n

A few fishfinders transmit data in full color directly to your smartphone and can provide even more detail than a handheld fish finder with a color LCD screen.<\/span><\/p>\n

Dimensions – If you want a handheld fish finder that can actually be held comfortably in your hand, dimensions are an important spec.<\/span><\/p>\n

Weight – Most of the portable fish finders are for models around a pound or less. If you like to fish in remote areas, a small and lightweight fish finder is a good choice.<\/span><\/p>\n
