Things to Consider When Buying a Castable Fish Finder
Apps
A user-friendly app can drastically increase the value of any castable fish finder.
As with any app-driven product, a castable fish finder is only as valuable as the interface which drives it. A simple, easy-to-use app allows an angler to optimize the effectiveness of their castable fish finder.

Connectivity and Range
To be used effectively, a castable fish finder must be capable of establishing a reliable connection with the mobile device that it is paired to.
Castable fish finders utilize one of two forms of connectivity, Bluetooth or WIFI. WIFI tends to provide a more stable connection, at ranges up to 300-feet. Bluetooth, on the other hand, presents a more limited connectivity range of 100-200 feet. However, Bluetooth fish finders are typically cheaper to purchase.
Depth
The deeper a castable fish finder’s operating depth, the more versatile such a unit tends to be.
The operating depth of portable fish finders varies significantly from one product to the next and can range from 100-feet to 300+ feet. The frequency of its sonar determines the detection range of a particular castable fish finder. A sonar unit’s frequency describes the number and frequency of sound waves transmitted within a given period.
Fishfinders that emit a lower frequency can reach far deeper depths but are not capable of relaying images in as high of clarity. On the other hand, depth finders that transmit higher frequencies can display images in remarkable clarity but are unable to reach as deep as depths.
Size and Weight
The size and weight of a castable fish finder directly influence the portability of such a unit.
While most portable fish finders tend to be compact, some are more sizable than others. The lightest of these products weigh only a few ounces and can be carried in an angler’s pocket, offering next-level convenience.
Sonar Method

Castable fish finders come in 2D and 3D sonar forms, each of which has distinct advantages and disadvantages.
2D Sonar

3D Sonar
As of late, 3D fish finders have grown immensely in popularity, mainly because of the high-resolution images that they portray. However, units of this nature do not tend to be as reliable as their 2D counterparts and command a much higher purchase price.
Versatility
A versatile fish finder is of significant value to every angler, no matter its specific type.
Some of the best castable fish finders come with additional mounts and hardware that make them acceptable for use in a wide range of settings. This extra versatility provides anglers with more bang for their buck and adds value to their investment.
