Best Castable Fish Finder – A Review of the Best Units in 2017

Fish finder offers information that help modern anglers peep through what’s happening underneath the surface. The best castable fish finder is equipped with the latest technology and features that have greatly stepped up from the old models.

How Does the Technology Work?

Without delving deeply into the technology and science of the gadget, fish finders work the same way dolphins use echolocation to navigate their way through the ocean.

Using a device called a transducer; sound waves are released allowing it to travel through water.

When these sound waves hit other objects underneath, it bounces back and transmits signal that is then interpreted in the depth finder’s receiver.

This signal is analysed and processed using the strength of the signal as well as the amount of time it took for the sound wave to hit the object and bounce back to the receiver.

With today’s technology, a small computer can determine the object’s distance thus making it a reliable and helpful tool in knowing the depth of the lake.

It also serves as a guide for safety such as knowing whether there are sunken trees or shallow sandbanks to avoid.

Of course there are different variations when it comes to the technology and the advantages a unit has to offer. Some fish finders are elaborate enough to send signals all over the lake.

Others send limited, but equally useful sonar signals to a single direction. There are also those devices that have dual screen color, while there are others that display information and details in full color.

The latest models are manufactured with many options to help anglers make the most out of their fishing expeditions.

In fact, these castable fish finders are proving to be one of the new portable must-haves for both hobbyists and professional fishers.

Portable vs. Castable Fish Finders

Do not confuse portable from castable fish finders because although they serve the same purpose, they vary in terms of usage and features. The primary difference, however, is on the size of the device.

Portable fish finders are usually attached to the bottom of the boat or placed in the water.

They have small transducer that sends signal underneath that is then interpreted and visualized in a small display screen.

On the other hand, the castable units are way smaller and more rugged. The transducer is attachable to the fishing line, which you can cast to the water. This is handy as it allows you to cast anywhere you want.

Each of these variations has its own advantages and disadvantages. However, a castable unit can be easily carried and used anytime, anywhere.

You can use it most especially for small areas like holes where you need to investigate what’s underneath it.

Bank anglers, most especially, can take advantage of the castable fish finders’ features as it is not only handy, but super light and easy to bring along without adding more weight to your gears.

The latest models do not feature a dedicated display so that the signal is sent directly to your smartphone through a free app.

PROS

  • Utilizes the power of your smartphone – a device you already own
  • Best for bank fishing, but also useful for boat fishing
  • Lightweight
  • Easy to carry and use anytime, anywhere

CONS

  • Works at a limited depth and range
  • Dependent on a registered smartphone for reading

How to Choose Your Castable Fish Finder

So you know castable fish finders are pretty handy. Most models in the market now offer great deals for your money.

However, there are three things you need to check to make sure you are getting the right unit for your needs.

  • GPS Capabilities
  • Range
  • Versatility and Additional Features

1. GPS Capabilities

You want a device that can map a lake or a pond. This feature is very handy if you are the type who likes to explore new bodies of water for fishing.

In fact, some devices are so advanced; you can map an entire lake or pond system from the shore.

Another cool feature about a unit with good GPS capabilities is that you can locate good fishing areas and find it again next time you go fishing.

This means you get to save time looking for fishing spots especially those that are quite challenging to find.

2. Range

Range can refer to the distance you can cast and receive good signal as well as the depth a transducer can send signal and receive feedback.

Most models today have impressive range for such a small device.

Recent units have also transitioned from Bluetooth to WiFi since Bluetooth tend to lose connection every now and then.

WiFi, on the other hand, is a more reliable and faster means of connection that allows you to cast farther than you could if your device is connected via Bluetooth.

Most models with WiFi connection now allow casting as far as 160 feet in a 150 feet-deep water and 100 feet for ice fishing.

Most devices instantly send feedback the moment it hits water.

Some units are very sophisticated that it can tell you the depth and temperature of the water, the landscape of the bottom, and most importantly, the presence or absence of fish within or around the periphery.

This means you want a device that can send clear, if not crystal clear, picture of what is happening underneath the water. Some anglers find transducers with multiple frequencies very useful.

Devices with a wide frequency, 381 khz, and a narrow frequency, 675 khz, send crisp and clear picture of what you can find below.

This allows you to distinguish fish from cover and other possible objects under the water.

If this is not enough for you to tell fish apart from other objects underneath, some devices also allows you to use real sonar data to analyse the objects below.

This is absolutely useful for ice fishing where it is hard to tell fish from other hard substances underneath the ice.

3. Versatility and Additional Features

As much as possible you want to invest on a device that is not only good for one type of fishing. You want to be able to use it in different modes, whether that means fishing from the shore, on the boat, or in the ice.

As far as additional features go, you can rely on different companies to manufacture the latest that the technology can offer.

There are devices out in the market with 5 transducers, for example, that is capable of putting out three different frequencies.

Some devices also offer different modes of fishing with unique features for each mode. Some have bottom contouring mode, which is useful for seeing drop offs or cliffs.

Others even have 3D mapping mode, which is pretty amazing considering castable fish finders are very tiny devices. These models allow you to see the bottom in a 3D map.
