A fish finder also known as a sounder is an instrument
that is used to locate a school of fish in the water by picking up reflected
pulses of energy (sonar). The reflected sounds appear as a graphical display to
enable the angler to ascertain the depth of the water body, the shoal of fish
and underwater debris. Here in this article, we talk about the choosing the
best portable fish finders and benefits of using some portable fish finders.
How to Choose the Best Portable Fish Finders
One of the three biggest items to look out for when
buying a fish finder is the GPS system. A quality GPS system is a central part
of a functional fishfinder. The second key feature is the sonar. You can have
either the down-scan or the side scan type of sonar depending on your needs.
Thirdly you have to consider the costs. Most often the lower the price, the
lower the quality, and utility you will get. There are other minor features
such as the power wattage, display screen size, the pixel, etc.
Benefits of a portable fish finders
One of the central benefits of working with a fish
finder is, of course, location. A functional fish finder makes it easy for you
to catch fish more frequently and quickly. Besides that, some fish finders come
with a transducer that gives you greater flexibility in moving around to
getting fish. Thirdly ice fishing is very easy for those with advanced fish
finders that have side-scans for fishermen in cold regions. It’s incredibly
difficult to catch in large water bodies without the aid of a fish finder.
Attributes that differentiates Fish finders
There are about six features that set part one fish finder from another. The difference is usually in quality.- The first one is frequencies i.e. Single, dual, & multiple. Most of them have the 50/83/192 or the 200 kHz.
- Secondly, is power. There are power units to fit with every type of fish finder. The power is measured in wattage (W).
- Thirdly is screen resolution. Screen resolution is simply the smallest possible detail your display can show.
- The fourth is transducers. These are the central units that emit and receive sonar waves.
- Fifth is color Vs. The B/W Screens. Advanced screens show vivid images as opposed to the 265 shades of gray that were used in older technologies.
- Lastly is the cone angles and beams. This determines how wide the beam is sent from the boat outwards in search of fish.
Best means of using the product
It’s critical that you
understand the particular use of the fishfinder at hand. There are fishfinders
for all range of prices from $100-1000. There are also specialty fishfinders in
the market. The most modern fishfinder for this category are the kayak
fishfinders. They are usually 5-7 inch fishfinders with incredible screen resolutions.
They are fitted with separate batteries that you store in the carrying case.
Sonar technologies have remained the most competitive part of a portable
fishfinder. Every year newer and stronger sonar systems are manufactured.
Questions that Generally Arise about Portable Fish Finders
One of the significant
controversies facing portable fish finders is the question as to whether sonar affects fish behavior. Some of the military sonars
have been linked to the panic stranding of whales and dolphins, though the
study is not conclusive. It’s vital to keep in mind that there are some fish
that have inbuilt sonar. The second controversy has to do with the electric
charge of transducers. There is a perspective to the effect that the electric
charge alters fish behavior.
With this in mind, here's our recommendation of five of the best portable fish finders
