If you want to get yourself the best fish finder out there, you need to pay attention to a set of very important details. Our advice to you is to read as many portable fish finder reviews as possible, as other customers’ opinions can help you make up your mind about what you need in a particular model and understand how reliable some units actually are. Start investing some time in your research and you won’t be sorry for your purchase.
Fish finders come in various shapes and sizes and it might look like it’s difficult to pick the right one. To make the right call, check out the following tips.
Cone angle and beam
One of the first things to consider is whether you’ll be fishing in shallow or in deep waters. The wider the cone angle of your fish finder, the less likely it is able to detect deeper signals. Transducer cones come with variable ranges, anything from 9 to 60 degrees. However, the cone angle of most available models stand somewhere between 16 and 20 degrees.
The beam is also crucial if you’re looking for a good transducer. The majority of older, less advanced models come with a single beam, while modern units have dual and even triple beam technologies.
Frequency and power
The rule’s pretty simple when it comes to frequency. The higher it is, the more detail you’ll be able to see on the screen. Nevertheless, it is important for users to understand that a higher frequency will not help them visualize targets in deep waters. Frequencies can be anything from 50 kHz to 200 kHz, and it is the second that work best for shallow-water fishing.
As for power, the higher it is, the better. With more watts, you’ll be getting a clearer picture and a faster reading of the area you’re trying to scan. Fewer watts will create a fuzzy image which will take more time to load.
In this case, size matters quite a lot. In this sense, older models are cheaper just because they come with grayscale technology and with screen sizes that resemble the ones of a retro cellphone. This brings up the following dilemma: maybe the transducer is doing its job properly but you’re not being able to see the image as well as you might need to.
Subsequently, we recommend you get a reasonable high-res color screen. The higher the resolution, the more detail you’ll see displayed. After all, who doesn’t want a crystal clear picture of their catch?
Situations where using a fish finder comes in handy
Regardless their shapes and sizes or the power or frequency of the transducers, these devices can make the difference when it comes to your fishing success depending on your habits and endeavors. Whenever you use a small boat or a kayak, you do not have the freedom of utilizing big devices.
In fact, there’s a shortage of space that you must manage as best as possible so as to ensure that you remain safe all throughout the fishing activity and that the rest of your angling companions are as comfortable as ever.
Portable fish finders, compared to their larger counterparts, are compact, lightweight, and easy to utilize. Despite the fact that most of the models that we have stumbled upon do not boast a waterproof design, you can use things like waterproof cases or covers, which you usually have to purchase separately.
Just keep in mind that the case or cover you will choose needs to be matched to the device you own. Therefore, if you have a unit that’s outfitted with a touchscreen display, it’s safe to say that you need a rather thin cover that’s able to protect the device from the occasional splash yet allows you to use the touchscreen functionality.
Type of data provided by the model
When it comes to fish finders, it goes without saying that no unit is made the same as the next. What this means is that, while some can provide you information regarding the depth, the bottom structure, as well as the weather and water temperature, others are virtually incapable of doing the same.
Versatility is another factor you ought to take into account whenever you’re in the market for such a product. While with some, you have the opportunity to utilize them as regular fish finders and as ice flashers, too, with others you can solely rely on the first type of functionality.
Batteries and runtime
Another aspect that needs to be borne in mind is how you are going to supply the power to your fish finder. In case you didn’t know, there are options that work with disposable batteries, be they AA or AAA. The fact of the matter is that these alternatives are often more user-friendly compared to those equipped with rechargeable batteries, and here’s why.
With devices that rely on disposable batteries or rechargeable battery packs, you always have the freedom to carry a set with you to ensure that your fish finder is ready to go whenever you need it the most.
On the other hand, if you do decide to go with a product whose internal battery needs to be recharged, we at least suggest getting an extra battery pack or a model that can be powered via a micro USB port. This particular feature will enable you to utilize all sorts of power banks that you might carry with you to supply power to your smartphone, for instance.
