What to Look for in a Portable Fish Finder

Before you read on our selection of portable fish finders, you must know what the important considerations.

  1. Frequency

Since the portable fish finders work on sonar technology, the frequency level is an important consideration. You need to remember that higher the frequency of your device, the more details of the fish you get. Most of the fish finders have a frequency within a range of 50-200 kHz.

  1. Cone angle

The cone angle means the net of the signal which will be cast from your device once it has submerged in the water. In deep waters, there will be wide cone angle, but the sensitivity may reduce. The usual range of the cone angles is 15-20 degrees.

  1. Power

The power of a fish finder is determined in wattage. This will tell you how active sonar can work. If the fish finder’s wattage, is higher; the unit will relay the live results fast. Generally, for 100 watts, a fish finder can relay results of about 400 feet depth.

  1. GPS power

Most of the fish finders have GPS system installed in them. The GPS enables the user to save the location and view them later. These locations may indicate the area with desired fish, or the areas to avoid which have obstacles.

  1. Portability

Since the fish finding requires much other equipment, and you cannot hold many things altogether, a portable fish finder should have a compact design. It should also be light in weight so that you can easily carry and store it wherever you want. Portable devices also come in handy when you are moving in a small boat or a kayak.


The portable fish finders and their sonar technology can prove to be of great help while catching the fish. Regular fish hunters will surely have recognized the importance of this.

Consider getting the locations of your favorite fish before you start hunting them. How easy and fun filled the experience would be. You would know beforehand about all the obstacles, the water depth, the temperature and other things.

Collection of all this data is only possible through a reliable portable fish finder. We have arranged this list after careful analysis, and we are sure that it could help you in making a great buying decision.
