What Are The Best Portable Fish Finders 2018
Here they are featured in the table below.
How To Choose The Best Portable Fish Finder
Being quite an essential tool of fishing these days, it is crucial for anglers to choose correctly with fish finders.
There is a lot of variety in the market and selecting one is not that easy. There are numerous features and applications to consider.
Happily, however, there are some fundamental criteria that should whittle them down considerably and make life easier.
Types Of Fish Finders
Portable fish finders come in three main categories.
There are versions that feature GPS tracking. These are ideal for anglers fishing out at sea and would need some direction with getting back to shore. They can remember prime fishing spots that have been visited before. They also have sonar which can paint a clearer picture of everything under water.
Then there is the standalone version. It also has sonar but no GPS tracking. Sometimes, however, these services may be offered for an additional fee. It is the best fish finding device for kayak fishing. This is mainly thanks to its sonar, able to deliver accurate readings of depth and temperature.
Finally, there are the fish finders with networking features. They are certainly not cheap. However, they will allow you to locate different hotspots or share pictures online.
The transducer is the part of the device that produces sound waves that generate images.
The key feature to look for with the transducer is the cone angle which is to say the beam width.
The more width there is, the more area that will be made visible to you. The angles of cones are commonly between 16 and 20 degrees but can vary from 9 to 60 degrees.
Other features to consider with the transducer are its frequency capacity and the kind of beam it emits.
Low frequencies are suited for deep water while higher frequencies are good for the shallows. For anglers who fish once every so often a single beam in their transducer is sufficient.
Any more than that would be more expensive but would also better your chances of landing the big game.
How Powerful Is The Portable Fish Finder
Power is a particularly important aspect of a good fish finder.
In very simple terms, the fish finder recovers information via the sonar emitted from the transducer. The more power your fish finder can generate, the faster its readings can be displayed.
Devices with a relatively low power output are best suited for shallow water.
These are some of the crucial equations to remember: 50kHz for each 100-watt output has a range of 400 feet. 200 kHz per 100 watts carries a range of 100 feet.
Screen Size and Resolution
Whatever your pick, it is best to go with as large a screen as you can pay for.
And make sure it can be seen clearly in direct sunlight as well as in low light.
A good benchmark for screen resolution should be 240×160 pixels.
This way, it will be easy to note what is on the screen while you are occupied with something else. After all, a portable fish finder needs to be as practical and efficient as possible to make a good fishing trip.
Colour screens are now becoming the norm with fish finders.
Their displays usually carry more detailed images can identify objects for anglers a lot easier than the black and white screens.
They are also a lot easier to read in appalling weather and in bright sunlight. That said, the more traditional black and white screens are still commercially available.
However, chances are you could do better with a color display on your new fish finder.
There are some delightful features in this area that may not be mandatory but still great to work with.
For instance, pre-installed maps of major waterways in a particular region or country, or an HD layout of the terrain underwater. Both these features would make fishing in unfamiliar areas a lot easier.
Other useful extras include a protective casing, suction mounts and easy ways of programming the device to find what you want.
After carefully considering the aforementioned criteria, you should be able to make a well-informed decision on your portable fish finder.
