Things To Look For When Buying A Depth Finder
Of course, you will be looking at a number of different depth finders, features, and functionalities. However, you need to look for a few factors that are a must. Therefore, we have combined the main things you should look for in the best depth finder.
Mainly, if you are planning on using your depth finder solely to find fish, sensors are a must! Basically, a sensor is what sends out and receives the sonar wave.
Once these waves are emitted into the water, it bounces off to find different objects underwater. Eventually, they get picked by the transducer.
When it receives the data that it needs, it directly goes into the central unit. The signals then get processed into a picture and appear on the display for you to see and understand.
Transducers also come with different types of mounts, the easiest one of which is to install the transom mount.
However, if you have a bigger boat, you will be needing something much seriously; perhaps something like the thru-hull mount.
What type of boat will you be using? Depending on that, you need to choose the right transducer material. For hobbyists and recreational fishermen, a plastic transom would do the job.
They are compatible with all types of boats. On the other hand, if you are using a transducer with a thru-hull or an in-hull mount, metal hulls or fiberglass need plastic housings.
Aluminum or steel hulls need the stainless-steel housings. Bronze housings are more necessary for boats with fiberglass or wood hulls.
Lastly, when it’s about recreational users, most of the fish finders come well equipped with trolling motor transducers with transom mounts.
The good thing about this is that it works with any kind of boats. You will just need to ensure to follow the installation guidelines thoroughly.
But if you still think that the idea of a thru-hull transducer is better, then your choice is between bronze and plastic only.
Colored screen vs Black & White Screen
Of course, color displays look better on all electronic devices, not just depth finders. They uphold plenty of details and offer up to millions of colors.
Whereas a black and white screen only has 265 shades of grey. Plus, black and white screens are harder to be read under sunlight, dark and cloudy weather. Colour screens are easier to understand and learn.
If you can’t seem to fit a color display depth finder into your budget, you might just have to choose a black and white one to get started with.
In addition, if the device is merely just to get a simple idea about the depth and find a few fishes, then a simpler model would be better to start with. You can always upgrade later.
Here’s a little though you need to put in: you need to consider what resolution and how many pixels your depth finder’s screen needs to have. In simple words, a pixel is just a dot on the screen.
The more pixels you have, the more details the depth finder’s display can put out. For instance, with a 320 x 320 resolution, 320 dots would be going from left to right and 320 dots going from top to bottom in each column.
What we’d suggest is that you should at least go for 240 x 160 pixels, if it’s your first time buying a depth finder. Even this might give you the feeling that you are playing Tetris instead of looking for fish.
If you have a little extra budget to spare, always go for a better resolution display that’s more likely to give you nice details and crisper images. It’s totally worth it!
In tune with the screen size, the resolution of the depth finder will decide if the picture of it is going to be good. Most cheaper devices have smaller displays. They make good backup options.
But if you are seriously looking for a fish finder, which needs to sustain for long, you need a bigger budget, larger display, and better-quality screen.
Only then you will be able to view the numbers and data on a larger screen. Some small screens sometimes even get cluttered up!
Before you jump on to pulling the trigger, you need to know the power of the depth finder. If you want a device that has faster and deeper readings, you need a high wattage unit.
Devices with lower wattage are likely to be slower and are more applicable for shallow water. This usually occurs because a depth finder converts sonar waves from its transducer.
When there is less power, the wave is slower, and hence the reading is also not reliable. When there’s more power, the readings turn out to be more accurate.
Long story short, if you plan on going fishing in shallower water, you don’t need a powerful depth finder. But if you prefer deep water or saltwater, you need to get a device that can afford much power.
Many individuals are looking for a transducer for a depth finder based on the cone angle, regarded as one of the essential characteristics. A depth finder’s cone angle works in tandem with its frequency.
The cone angle is when a beam goes down through the bottom of your boat, and it starts to grow wider. It starts as it narrow at the top and gradually widens as it goes deeper into the water, much like a cone.
Cone Angle is also known as the transducer beam angle.
- Your depth finder will show depth readings of up to 400 feet with every 100 watts of power at 50 kHz.
- Your depth finder will read up to 100 feet with every 100 watts of power at 200 kHz.
Most depth finders in the mid-range operate with dual frequencies, which helps you to see readings from every spectrum in a split-screen mode.
Last but not least, you need to consider water resistance. Why? That’s because if you plan on mounting it on an open vessel, chances are it will come in contact with water.
In that case, check the IPX or JIX ratings that determine the device’s resistance to water. If it has a rating of four out of five, it means that the device is safe and water splashes won’t have any effect on the device.
Consider yourself lucky if your device has a rating of seven because it means that you can sink your device for a good 10 – 30 minutes and there’s not going to be much of a problem. The rating makes a huge difference.
Just like any other gear, you need to pay close attention to details when looking for the best depth finder. These devices are all very well advanced and equipped to last you years with proper maintenance.
If you invest a decent amount on it, you will find an excellent 3D mapping, charting, scanning and navigation features. It’s not like you have to spend hundreds unless you really want a high-end depth sounder.
Also, don’t forget to look for products that are easily upgradable (both hardware and software).
As we had mentioned before those multi-screen finders make your fishing experience so much better, in tune, you also need to pay attention to the power output in watts and the display size and clarity.
If all goes well, the brands that we have mentioned are all excellent. Lowrance, Humminbird, HawkEye, and so on. All of them have rugged construction with a basic operation that provides stress-free performance.
So, ladies and gentlemen, this article on the best depth finder will help you guide you through the best and we hope that you find what fits your needs. You will be thrilled to find out about some of the most amazing things that these depth finders could do.
