Buying guide

 

A castable fishfinder features a small transducer that you attach to your line, and the display can be a portable device such as a smartphone or tablet. This enables you to look for fish or read the depth right where you cast. To be able to get the best castable fishfinder for sale, you either have to do a lot of research or just take note of these essential aspects.

Power and frequency

The strength of the ‘ping’ signifies the power of the device. This is expressed in root-mean-squared. Power is directly proportional to how clearly you can see in the murky water and view down to greater depths. It also determines how separate targets and bottom structures are resolved.

You can expect enough power from a 500-watt model for most coastal purposes. For serious saltwater fishing, aim for 1,000 watts or more.

The best portable fish finder boasts a transmitter capable of sending out an electrical impulse strongly to the transducer, which in turn, converts that into a sound wave. The sound waves are sent into the water where they bounce off the objects there and are channeled back as echoes to the transducer.

The results are read back as electric signals amplified by the receiver, and that can be viewed on the display. Unless the castable fishfinder is equipped with a powerful transmitter and transducer working together, your readings will be fuzzy, and the sonar waves will be slower. Conversely, with dependable power in those components, the waves will be much faster and the readings much clearer.

That said, you need less power if you fish in shallower water. However, if you intend to fish in deep water or saltwater, you need the most powerful castable fishfinder available on your budget.

One nifty transducer feature is when it has more than a single cone transmitting from a single starting point. This means while a standard transducer features a single beam, the more advanced ones boast a dual beam, triple beam, side beam, and even greater depth. With more beams available, you get more coverage in the water of the fishing spot.

 

Depth range

Any angler would want to know first what depths they are fishing in order to choose a device that offers the maximum depth range to suit their needs. While costlier models pay off at the scales, you will need to make sure that the device you go for in the best castable fishfinder reviews delivers more definition at deeper depths.

In the end, it all boils down to which unit has a transducer that ‘listens’ better. If you fish mostly in shallower waters, there’s greater disadvantage in a narrow beam. On the other hand, the wider the beam is, the longer the target remains in the generated cone. For game fish, looking at the top 200 feet of the water column should be enough. Any deeper than that and you have a top notch model.

 

Helpful features

All the major manufacturers offer fully-networked systems that will generally support a wide array of data sources such as raster and vector, radar, GPS charts, satellite radio, and video. Plenty of the best smart fishfinder units support WiFi/Bluetooth, and they can be controlled using your Android smartphone or iPhone.
