Fish Finder And Their Types

The categorization of the fish finders has been done in three types of locators:

Ø Standalone

The basic role of locating fish is being pursued by a standalone fish finder. There are no extra features attached to it and you get them at a very affordable price. These types of finders come with a wide screen and are suitable for simple purposes.

Ø Network System

As the name suggests these types of finders are connected to technology as Bluetooth and Wi-Fi along with GPS charts and even satellite boat radios too. The screens of these are wide and include videos too. They are incorporated with comprehensive features and this depends on you if you require all this in your depth finder.

Ø Combo

These work marvelously as the information you can get is much more than just fish finding. You can know the depth and the water temperature also if you invest in this type of depth finder.

Don’t be surprised! they give you a detail about the size of the fish too. They also include GPS, have comprehensive features and provide you with enhanced viewing experience.

The Most important things to be kept in mind while purchasing the Best Depth Finder

There are many things that should be considered before you make a final decision to buy the best depth finder.

A. Transducer

It is very necessary to have sensors as they work to receive and give sonar waves that get emitted into the water. The waves that are generated bounce on the objects present in water and are caught up by transducers. This helps in finding the fishes in the deepest depths and the signals get processed into pictures, thereby displaying on your screen.

You can understand things better and clearer and the transom mount transducers are easy to mount and install. Humminbird HDR650 is supposed to be the best transom mount that provides the apt information.

B. Transducer Material

The boat type you use will make you decide the material of the transducer. Any one doing fishing as a hobby or for recreational purpose then a transducer of plastic is sufficient. A transom that shows compatibility of all kinds of boats is the right one.

Fiber glass or metal hulls require housings of plastic and will prove great for in-hull or thru-hull mount. For wood hulls or fiberglass bronze housings are recommended and the entire choice is yours. The guidelines for installation should be thoroughly followed and the mounting should be done properly.

C. Colored screen or Black & White Screen

Colorful displays are always welcome for any of the electronic devices you choose and use. The beautiful spectrum of colors gives beautiful detailing. If we talk about black and white screen then we are left with varied shades of grey providing you with least color choice.

The readings are clearer on a colorful screen than the black and white ones. You are under the exposure of sunlight so colorful screens is a far better option. Furthermore, you can go for upgradation too later if you want.

D. Screen Resolution

We are concerned about pixels here, as these are dots on the screen. The simple thing is that the more the pixels the more clarity of pictures your screen will deliver. If you have a resolution of 320 x 320 then the whole screen will have dots vertically and horizontally 320 covering the whole screen.

Images of good screen resolutions are perfect and you can choose according to your budget. Larger displays will definitely provide you with quality images, and you should choose a one with a good resolution. Small screens on the other hand may get messy though they have good back up options. If you are doing some serious fishing then go for a product that goes for long. The numbers are also more-clear on a screen with good resolution.

E. Power

If you want readings for deep waters then more wattage unit is required as the slower ones will be of benefit for shallow waters only. The rule of the thumb is, more depth then more powerful the depth finder you require, as you jump in and pull the trigger, they should work properly.

F. Taking readings

If the power is 50 kHz then the depth finder will help you have readings up to 400 feet (every 100 watts of power). With 200 kHz power it will give readings till 100 feet (every 100 watts of power). Mid-range depth finders have the ability to function with dual frequencies.
You will be able to see the readings properly on your split-screen mode.

G. Water-Resistant:

Since it is all about water, the depth finders may come it the water contact when installed on an open vessel. There is a need to check IPX and JIX settings when you buy a depth finder, as this will ensure you the water-resistance levels of the depth finder when any splashes occur. A rating of 7 is supposed to be good that will give you more flexibility to take the device to depths up to 30 minutes.


By now you must be well aware about what a depth finder is like! Invest in the best and enjoy fishing as a hobby or recreation. The 3 D mapping, navigating, charting and scanning, all can be done with these little but magical devices.

The close details need to be studied always, be it for the depth finders or any other gear. Enhance your fishing experience by investing in an excellent depth finder. You can choose one according to you budget and try to opt for the one that can be upgraded for future use.

Stress free performance with these robust constructed devices can be obtained and make the most of it while your water tour.
