Depth Sounder

A depth sounder is used on-board of a vessel as a way to calculate to depth of the water underneath the vessel. The device can also be used to calculate the depth of the water in correlation to your vessel and an object underneath the vessel in the water. This can be a beneficial piece of equipment for a number of reasons. For instance, a depth sounder can be extremely helpful when attempting to find fish nearby your fishing boat, and it can also work to determine the size of the fish as well.

A depth sounder is not specifically used as a fish finder. There are other reasons why a depth sounder device can benefit you while out in open water. If you were near a shallow area with your boat then the depth sounder could help you determine what direction is safe to go, and where is too shallow to get through safely.

There are still more uses for the depth sounder as well. You could use the depth sounder device to determine the aquatic foliage and rockiness within a particular area. This is just one other example that further displays that the depth sounder is a multifunctional device and not just used as a fish finder.

Sonar (Sound Navigation and Ranging)
Sonar is a method that utilizes the generation of sound underwater to get information on your vessels location and the location of vessels nearby. Sonar exists as either active or passive. The sonar system can also operate at various frequencies ranging from infrasonic to ultrasonic. These are the two extremes for this particular type of measurement.

The sonar system will allow you to navigate through open waters easily and can prevent a variety of possible accidents or unwanted incidents from occurring. This is the technique used in both depth sounders and fish finders and is very convenient regardless of what your goals may be. With the sonar system you will be able to determine when there is a fish nearby in the water. The sonar system will also allow you to determine when you are close to the ocean floor.

How It Works
While your vessel is moving it will create a wave. The same thing will occur when there is another vessel nearby, or a fish is in the water near your vessel. The waves produced will have a short time delay and the wave size displayed will show this as well. Once the device locates the waves underwater it will show up on the digital screen.

Depth sounder devices can work differently depending on the design. Many are just created to display the depth data but there are a few designed that show an accurate 3D display. The diagram displayed on depth sounders with 3D imagery will show the water depth, where fish are located, and more.

How Important Are Depth Sounders?
Most boats can benefit dramatically from having a depth sounder on board. They become extremely beneficial when you have a larger vessel as it is extended further down into the water. With a boat that is further submerged into the water it can be difficult to determine how far from the ocean bottom it is sitting. With a depth sounder you can prevent possible accidents as a result of this.

Another example of where a depth sounder can be extremely beneficial is if the vessel has large (external) propellers. Similar to vessels with extended bottoms underwater, you have to be cautious that your boat does not hit the ocean bottom. If this does occur, your vessel could become damaged. A depth sounder will allow you to navigate the marine safely and it will prevent you from going through shallow areas.

When buying a depth sounder you will want to look for a high quality model. Usually the expensive devices are the only recommendable models. The cheaper depth sounders have a number of issues and are nowhere near as precise and accurate as the higher priced models.

A cheaper depth sounder could read stones, aquatic foliage, and other objects underwater as fish, which could be an issue. This is not always an issue but with a more expensive depth sounder you will be guaranteed extremely precise navigation.
