Any avid fisherman understands the thrill and excitement of a good day’s catch and the disappointment of spending your day in the sea and coming out empty handed. In order to ensure productivity and more fun while fishing, the anglers might want to carry along some fish finders.
Most of these gadgets are plug_and_play and are made to easily fit into a kayaks bottom. However, fishing kayaks that are not designed to hold fish finders can have it drilled and mounted onto the boat; although this is not advisable since it makes selling or trading the kayak impossible. Below are the components of a good fish finder;
The transducer is the signal sending and receiving component of a kayak fish finder that is either mounted on the inside of a kayaks hull where the signal is shot through the kayaks material or it can be mounted from the scupper hole using a pipe. Data that is picked by the transducer is then sent to the main unit where the signals are converted into visual images that can be understood by anglers.
Depending on the intended use, and the type of fishing kayak that the fish finder is to be mounted on, transducers are made from various kinds of materials. Unless otherwise stated, most beginner transducers are made from plastic. These are perfect for most recreational and sports fishing enthusiasts. They are also compatible with most fishing kayaks and boats.
Transducers that have a plastic housing should be used on hulls that are made from metal and fiberglass. Transducers that have a housing made from stainless steel are best suited for aluminum and steel hulls while fiberglass and wooden hulls would get the best results from bronze housed transducers.
Once the data has been conveyed to the main unit from the transducer, it is then displayed on the screen. Kayak fish finders should have a screen that is around six inches. Anything more than this is usually too much especially considering that the space on fishing kayaks is limited. In most cases a ram mount is used to mount and fasten the display to a kayaks side.
Any display that is more than 7 inches would mean increasing the weight on your kayak by more than 6 pounds which is not advisable. Apart from the size of the screen greater consideration should be given to the pixels that a screen displays. The bigger the number of pixels usually means a better image. The resolution of many fish finder displays range from 240 by 240 to a high of 640 by 640 pixels. For images that are crispier and sharper it is important to invest in kayak fish finders that have a high resolution screen.
Every electronic gadget or system must have a source of power in order to function; and so does a kayak fish finder. Most people prefer the marine battery that is built into a waterproof box with wires that are then ran to the display and the transducer. Those who do not like all the wiring on a kayak may opt for the portable battery powered fish finders. These come with waterproof cells that are popped into the gadgets.
