Buyer’s Guide

Fish Finder’s Performance

Castable fish finders are convenient and can be used in vast seas or big lakes to scan the deep waters. However, if the performance of this castable device is not on point, there will be no fun in fishing. Shore anglers rely on the performance to spot fish and then cast the fishing line.

If you cast the fish finder far from the boat and it is able to cover a wide range from the boat to that particular distance, you will not be needing any other fish finder. Deeper fish finder, and even Garmin fish finders offer a wide range of scan.

Scan Depth – Chirp

A wireless fish finder with excellent castable sonar units will be a perfect way to scan depth of the water body. If a casual angler gets a fish finder with more scan depth, the achievements of catching big fish will make him/her a more seasoned angler within a few trips.


Any fish finder that is not durable, will not be a good investment. probably one of the first features to look for in a fish finder is the life span, and how sturdy it is to sustain the crashing, splashing and all other things that are part of the fishing adventure.


When shoreline fishing, you might need higher frequency to scan the lesser depths. However, if you are ice fishing, the frequency requirement would be lower. You must select a castable fish finder with varying frequencies so that it remains suitable in all water bodies. A good fish finder and GPS will be an excellent selection if you select one that has more than one frequency setting.

User Interface & Ease of Use

Who would want to use a fish finding device that is so technical that it takes away the thrill of fishing? An easy and simple interface is what everyone looks for. Instead of getting impressed with too many buttons, or a technical device that may require too much time to set up, pick a model that will be easy to use. The best castable fish finders reviewed here are easy and results are always great.

Charging Time
