HOW TO CHOOSE A FISH FINDER
Portable or fixed
Buying a portable or fixed fish finder depends on the type of fishing you plan on doing. Portable ones usually work well for those who casually fish with rented boats. It is also usually built to be more compact. This works well if you tend to travel a lot for fishing in different destinations.
Fixed fish finders provide more security. It is permanently attached to your boat so that it does not get lost. Usually fixed fish finders are the favorite choice for boat owners. It is usually built with a higher resolution and wider screen for ease of use.
Depending on your fishing needs, a lower wattage fish finder is sufficient for shallow waters. In deep waters, then a higher powered fish finder would be able to manage deeper readings. With a higher wattage, sonar waves are converted much faster. You get your readings much quicker and more accurately.
Most mid-range finders available on the market are dual-frequency. At 50 kHz, for every 100 watts of power, your transducer can show readings up to 400 feet. Among all the kayak depth finders, this one will show the depth readings up to 100 feet for every 100 watts of power at 200 kHz.
Even though fish finders are used close to water, not all of them are built water resistant. To check its water resistance, look at its IPX (International Protection Rating). It gives you a clearer picture of how water resistant the item is.
IPX-0 = No protection
IPX-1 = Protected against condensation or dripping water falling vertically
IPX-2 = Protected against spraying water when tilted up to 15 degrees vertically
IPX-3 = Protected against spraying water when tilted up to 60 degrees vertically
IPX-4 = Protected against splashing water from any angle
IPX-5 = Protected against low pressure water stream from any angle
IPX-6 = Protected against high pressure water stream from any angle
IPX-7 = Protected against water immersion. Immersion for 30 minutes at a depth up to 1 meter.
IPX-8 = Protected against water submersion in under water conditions.
So having a device with IPX rating of 7 and above means the device does not easily damage if you accidentally drop it into water.
Having a fish finder with GPS functionality helps to navigate to multiple fishing spots. You can map out your waypoint and organize your fishing itenary for the entire day. This saves time from fishing in circles. However, if you just intend to fish at the bank, then having a GPS functionality may not be useful.
Depending on your budget, having color displays offers you the ability to better see what is going on in the water. If you are tight on a budget, then start with a black and white display. Once you get the hang of it, you can upgrade to a color display.
Whether it is sunlight, or cloudy days, better readability is affected by the number of pixels on the screen. The higher the pixels, the more detailed your image is. It is recommended to have at least 240 x 160 pixels for sharper and crisps images.Screen sizes is also another factor that affects the clarity of your display. The bigger the screen, the more information can be displayed on your screen e.g. data, number and echos.
Beams and cone angles
Transducers are a part of every fish finder. It sends out and receives sonar waves. The signals bounce off from the objects below and get picked up by the transducer. These signals are then translated to images that you can understand.
The cone angle reflects the width of the beam that is sent from your boat to the water. Cone angles range from 6 to 60 degrees cone. Having 16 to 20 degrees is sufficient for a beginner. Some transducers have multiple beams, which enables you to cover more areas, like large lakes.
The higher the frequency, the more incredible the details you can see on your screen. This is because higher frequency sends more sonar waves out of your transducer.
