Depth Finders Tell You A Lot More Than Depth

Author : Peter Gitundu


         


Let's be real: The truly fun part of fishing is when you get that tug on the line and you are reeling them in. It is too bad that there are days where that just does not happen, and the only thing you have to show for your work is a tomato red sunburn and a body full of organs that are saturated with beer. Those days are pretty much all in the past for individuals who own depth finders.

These handy devices go by another name, fish finders. They can show you what is under water for depths of up to 100 feet. They can keep you from damaging your boat in shallow water, and they can also help you see where you should drop you line and what depth to keep your lure. It might not qualify as shooting fish in a barrel, but it is the next best thing.

They use SONAR technology that was created by in just after World War One and used in World War Two, as a way to find submarines. After the war its use was expanded to some large commercial fishing vessels. The cost was so high and the hardware so bulky is would be decades before it would be available for individual consumers. That time came by the mid to late 1980s Since then, they have become even more affordable as well as portable.

In very simple terms, here is how depth finders works: They project an electronic sound signal into the water. The sound wave is cone shaped and gets wider as it projects out. Whenever it hits any kind of object, the bottom, a fish, weeds, a sunken car, you name it; the the wave is reflected back to the device.

The shape of the sound waves as they come back is how the images are created. The data regarding the depth is figured by the time it takes to come back.

Some fish finders are also GPS devices. GPS stands for Global Positioning Satellite. Any time you find spots that are yielding you a lot of catches, you can mark it with the GPS function and be able to return to the exact location easily. It can be a real life saver if your boat ever becomes disabled. You will be able to give rescuers your exact coordinates.

If you fish a lot, depth finders can easily pay for themselves several times over. The less expensive units are less than one hundred dollars. Even the ones in the thousand dollar range, given time, can pay for themselves with all the extra fish you will catch.
