How Accurate Are Depth Sounders?

Nowadays, boats come with all sorts of accessories that make fishing and sailing easy. One of those devices is a depth sounder. This is a must-have device — and not just for safety purposes, but as a help if you’re going fishing. Most of the time, depth sounders are used as navigation tools. The last thing you want is to find yourself in shallow waters. And as the name suggests, it tells you the depth of water you’re in.

As you may know, fish like congregating around structures. Depth sounders make it easier for you to locate those structures, hence, making it easier to fish. Even if you don’t have a boat and are considering fishing boat rental, get one with a depth sounder, as it will make your experience much easier.

How Do Depth Sounders Work?

If you have never used a depth sounder, you may be wondering how it works and if it is accurate. Essentially, the device can detect the depth of water and the presence of fish. While the screen is what gives you data, the most important part is the transducer, sitting below the water. The transducer transmits sound waves to the ocean floor. Those sound waves usually strike a target, which can either be the bottom of the sea or fish. Whatever the transducer picks up is signaled back to the depth sounder.

Note that the details recorded on the screen can be affected by several factors, including the unit’s range resolution software. For instance, a high resolution can record multiple fish targets separately. However, a low resolution can record two fish targets as one. There are different brands of depth sounders out there, and each operates differently. The better the quality, the more accurate the device.

Depth Sounders for Shallow Water

If you often fish in shallow waters, you don’t have to worry so much about the echo or image quality of the sounder. Usually, high-quality sounders are better for deeper waters to minimize interference. But when it comes to shallow waters, like ten meters or less, there is very little chance of interference because the transducer is closer to the base. Obviously, you have to think of navigation too. But entry-level depth sounders are still reliable in shallow waters.

Depth Sounders for Deep Water

If you usually fish offshore where you can drop your line more than 50 meters, you should get a high-quality sounder. If you are leaning towards boat rental, ensure the boat’s depth sounder is of high quality. A quality sounder has the ability to counter any interference associated with deep waters. For instance, the transducer can emit more frequent pulses, allowing the sounder to give you responsive images and readings. Also, note that the installation is important. When transducers are not well installed, they can damage underwater structures.
