In this blog I want to give you some tips on how to select a fish
finder. The process can be complex, so I hope this will help.
There are 5
factors to keep in mind when purchasing a fish finder.
1. Transducer
There are two basic types of transducers, single frequency and dual
frequency. Single frequency should be used for lakes and shallow coastal
fishing and dual frequency for deep sea. Dual beam (Humminbird) and dual
frequency are basically the same thing. The dual beam transducer will
limit the beam size for the high frequency beam so you only want to use
them in deep water because the high frequency is what you see fish
with.
2. Display resolution
Fish Finders and GPS units come in many different display resolutions.
The higher the resolution the better the image will be. Color screens are
better especially for direct sunlight because you can see them better.
3. Display size
Displays range in size from four inches to seven inches and larger. The
larger the screen, the more you have to pay for them.
4. Power
For the most part the more power you can get the better. In lakes and
shallow waters it is still important for better imaging, again, the more
power the bigger the price tag.
5. Depth
The ability of the sonar to reach greater depths is directly related to
power and quality of the transducer. The more you pay the better they will
penetrate the water. Remember that the depths shown on the specifications
are for clear water, saltwater and murky waters will limit the depths the
sonar will penetrate. |
