Buyer’s Guide: Get The Best Castable Fish Finder in 2023
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.
Whenever you pick a fish finder or any other device for that matter, how properly it functions is the first aspect you want to check. I admire that you’re going about it the right way. Castable fish finders are infamous for claiming picture-perfect outcomes that usually don’t exist in the fishing world.
Take the example of the Deeper Chirp Smart device. It boasts an operational range of 330 feet, but I can tell you from experience that what you actually get is around 250-260 feet. Unless you have a picture-perfect fishing environment where the location is right in the heart of the city, the connection on your cell phone is NASA-strong, and there’s no turbulence or current in the water, this is the maximum range you will get. So, reduce the expectations a bit from what the device claims.
All being said and done, it is still one of the best castable fish finders on the market because of its target detection and navigational aids. I only want you to not get your hopes unrealistically high.
Easy to Operate
The second most important thing I insist you notice is how easy it is to operate the product on whom you’re spending your hard-earned fortune. The unit should be packed with the latest technologies and most in-demand bells and whistles, but its operating mechanism should be so easy that you could confidently give it to a beginner as well.
The reason why I get all starry-eyed about models like Deeper Chirp Smart, Deeper Pro and Joylog Smart Sonar is that they have an extremely undemanding setup and use. Operating any of these is actually a cinch.
Next comes the durability of the product. Your casting fish finder needs to be more hard-wearing than other variants of fish finders because you will be projecting them from rocks, shorelines and stumps several times throughout the day out. Only a durable unit will hold up against such casting forces and harsh falls. A flimsy or average-quality fish finder will die on the first beating, wasting your money.
Charging and Battery Runtime
Battery runtime decides the length of your stay near the water unless you have packed extra batteries for backup in the stuff. I have no hate for a battery offering 3-4 hours of juice on a full charge, but such a short span is generally productive only for seasoned anglers who can seize the first catch of the day in an hour or two.
Those less-experienced ones who have to experiment with spots and casting lines to ensure success need more time. Well, there’s no harm in spending more hours near the water.
Therefore, I always prefer units having sturdy batteries that can offer at least 6-8 hours of non-stop action. Plus, they must juice up the battery in an hour or two to keep you from waiting too long.
How to use a castable fish finder?
Depending on the casting fish tracker, anglers can deploy it for action through several techniques.
First, you can fasten it to the end of a fishing line or a bottom rig – close to the meeting spot of the hook and sinker snood. It is an effective technique for shoreline fishing.
The second method is to hang it right off the edge of your trolling motor vessel. The said tactic improves the outcome of drift and ice fishing applications.
Why should I use a castable fish finder?
A castable fish finder makes the challenge of catching a fish not so challenging anymore. It offers an easy and practical alternative for hook lines, spinners, spoons, baits and ancient spears to capture finned targets. So, in place of luring fish with bait, you can launch a castable fish finder to know where the prey is loitering.
What is the best castable fish finder for the money?
Among countless products currently available in the market, my top picks are the following few;
- Deeper Chirp Smart
- Deeper Pro+ – Best overall.
- ReelSonar iBobber – Best value choice.
- FishHunter Portable
- Lucky Handheld Fish Finder – Best budget-friendly option.
Is a castable fish finder reliable and worth the money?
Yes and Yes to both questions. Although their accuracy and sensitivity aren’t as spectacular as boat-mounting larger sonar variants, they sense the presence of fish, no doubt about that, as soon as you launch them.
As for whether they are worth it or not, they most certainly are because they compensate for the loss of precision with versatility and affordability. They offer a stunning performance during ice fishing, shore/dock fishing and drift fishing. These units cost 2-3 times less than most fixed and mountable units.
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.
