Buyer’s Guide: Get The Best Castable Fish Finder in 2021
There are several factors in play that can make a castable fish finder a success or a failure for you. Therefore knowing about them is vital if you want to stay ahead of your peers in your fishing game.
Casting range of a fish finder means how far it can be tossed without losing connection with your phone or tablet. Most common castable fish finders come with a range of around 130ft which is sufficient for the majority of fishing habits. However, if you are planning to throw it at a large distance in order to avoid obstacles and interferences then Wi-Fi models are a better alternative.
As it’s evident from the above reviews, castable fish finders can sync to your phone either through bluetooth or Wi-Fi connection. Devices with bluetooth connection are generally more affordable but they have a limited connectivity range of around 130ft. On the other hand, Wi-Fi carrying models, though more expensive, can expand functional range to over 300ft and are also more reliable counterparts.
Depth & Frequency:
Depth scan and accuracy of information is dependent on the sonar frequency of a fish finder. Devices with higher frequency will cover a wider section of water and give precise information of the world below the water surface but it will be unable to travel deeper towards the bottom. Low frequencies can penetrate deeper but they lack detail. There are many models that feature both, high and low frequency, to let you switch according to the situation.
Fish finders present information in either 2D view or a 3D display method. 2D is the simple side-scrolling view that offers information about the riverbed or sea floor but the detail about depth is missing.
On the contrary, 3D is the most advanced method that provides in-depth and accurate detail about bottom contours, structure, fish and other underwater objects. Many models employ bathymetric maps to combine GPS information and depth measurements to fill in the remaining missing blanks in order to get a wholesome map of a waterbody.
Weight is the most vital aspect of a castable fish finder as it determines the casting distance. A simple rule of thumb is, the heavier the device, the easier it will be to cast it as far as the range allows. However, bulkier devices will need a stiff fishing rod and extra casting gear. If your fish finder is a Wi-Fi carrier model, you definitely want to make the most of the available connectivity range. Anything around 3 ounces of weight will ensure things run smoothly over a long distance.
Now that you’ve all the necessary information regarding the best castable fish finder, I’m sure finding the right model won’t seem an overwhelming task anymore. All the above models are loaded with nifty features, some more in numbers than others, to ensure your next fish hunt ends with at least a few of your targeted catches. In order to achieve the best possible value for your money, the buyer’s guide will prove very benefitting.
