How To Find The Best Portable Fish Finder of 2019
Getting a portable fish finder that is not built to do the job you need it to will cause you losing money, time and some good time. It is very important to know the factor to land the best portable fish finder for your cause. There are tons of handheld fish finders available in the market, and only a few portable fish finders to meet your needs. Before making a buying decision, I request you to consider all of these factors to make the process simpler and effective.
One of the most important things about choosing a portable fish finder is how much it weighs. It may sound silly, but it really is a crucial point to consider. Since you are choosing it for its portability, you really don’t want a heavy device to carry. Though most portable fish finders are small and lightweight, you may still want to check the weight. In that way, you won’t have a bulky backpack to carry when you move.
The small a portable fish finder is, the better it will suit in your hand. For most handheld fish finders, you will look at the dimension and see if it fits your hand or your bag. A fish finder with a poor dimension will cause you trouble holding or keeping it with you. If you are in a water vessel, I would suggest you choose a compact device with good features.
1. Portable Units
You are most probably looking for these types of devices. These are portable, offers excellent features, takes fewer spaces, but occupies one of your hands. Some of the portable fish finders don’t even come with a display. However, most of them will come with the display. Devices which don’t come with the display will use your mobile or tablet’s display to show data and readings. Usually, a portable fish finder will come with a screen from 3” to 7”. There are some exceptions, but most will fall in this range. You can use them for kayak fishing, shore fishing, ice fishing and other types of fishing.
These are the types of fish finder which will use your mobile or tablet’s display. A castable fish finder will come with a transducer or a device which acts as a transducer. You will have to connect it to your phone via their app, and you will start getting readings and other data on your phone’s screen.
Some portable fish finders will come with temporary mounting ability. Assume you are using the Deeper portable fish finder. It also has a mounting option. So, you can mount the device while you stream the data on your phone.
Most people love the big display. However, for portable fish finders, the screen is usually small. It is intentionally done to keep the device small and portable. Though the screen of the device will vary from 3” to 7” in most cases, there are some devices with a smaller and bigger screen. Try to get a portable fish finder with a good display with high resolution. You should look for a clear image as it will allow you to see the readings more clearly and accurately. A bigger display will help you to see multiple data at the same time, but the device will get bigger too. It is up to you to choose the size of the screen of the device. My suggestion is to choose one with a color display with good resolution.
A transducer transmits cone-shaped sound waves to the water. It returns back and gets received by the receiver, and helps you know what’s below the surface of the water. If the cone is wider, it will find fish and large structure faster than a small cone. Assume you are using a floodlight and a spotlight in a dark area. And you are looking for a ball, which one would find it first? Floodlight, isn’t it? Once you find the ball with the wider cone, you may want to know more. In that case, you will use the smaller cone to pinpoint the position.
Same applies to fishing. You will use the wider cone to scan the area, and you will use the smaller cone to pinpoint the object. It’s more accurate and saves a lot of time.
Fishfinder uses ultrasound frequency ranging from 15 kHz to 200 kHz. However, you will find most fish finders using 50 kHz and 200 kHz. To handle these frequencies, a fish finder will have a transducer mounted on the bottom of the water vessel. If you are using your fish finder in shallow water, it is suggested to use 192 and 200 kHz frequencies. On the other hand, 50 kHz is better to be used for deep water fishing. However, note that the higher the frequency is, the better-detailed reading will be shown on your display. It’s because the higher the frequency, the more sonar waves will be sent and received by the transducer.
- Higher frequencies: Best for shallow water, less coverage, better details
- Lower frequencies: Best for deep water, broader coverage, lesser details
Depth reading is one of the crucial factors to choose when looking for a portable fish finder. Most of the mentioned depth reading limit is based on clear water. It will surely change when you are trying to read the depth in salt, muddy or unclean water. Try to grab a device which offers more than 10% of your intended depth reading requirement.
There are several factors which need to be taken cared of like the beam, frequency, price. I will write another article in the coming weeks about how to choose the best fish finder for you. However, you can see the pros & cons and decide for yourselves. Check the Amazon links for prices and availability. I hope you get your best portable fish finder for the fishing. However, you can also check kayak fish finder and underwater fishing camera also.
Whatever you do, don’t go for cheap devices if you have enough cash. Fishing is an art to me, and I want to make the best out of it. That’s what I believe. Happy fishing.
