Ensure that the mount is secure though. You don’t want to lose your fishfinder because the mount was either faulty or installed improperly. Most products will come with the mount and screws so you don’t have to worry about going out and picking anything up.


If you come across a “fixed portable fish finder” then let me know, because that defeats the purpose of having a portable fish finder doesn’t it?

All portable fish finders will be able to be moved by hand whenever you need to move them. That’s the whole point of having a portable fish finder. So, if you need to be able to easily move around your fish finder then stay away from anything that says fixed.


Here is what we’re all here for. Portable fish finders come in all different sizes. Most can be carried in a tackle box, by hand, or inside of your pocket.

When To Use a Portable Fish Finder?

Anytime you want to have something small and lightweight in your pocket, tackle box or floor of your boat is when you can be using a portable fish finder. The lightweight makes it great for this.

Cone angle

Think of the cone angle as an upside-down ice cream cone. It shoots out from the transducer and then the transducer receives back the information that is within the range of the cone.

A larger cone is going to give you a larger area that you can see. Ideal for fishing in deep waters and jigging. However, a narrow angler is going to give you more clarity of what is directly beneath your boat.

Side Scan Vs. Down Scan

Side scan is going to give you an image of what is on the boat. Allowing you to see a laydown that might be twenty yards away and locating a fish sitting near it.

Down scan tells you exactly what is beneath the boat. This is great for fishing in deep water and you want to jig. This way you can hover over a fish and bounce your jig just in front of its face.

Mounting Type

The type of mount you use is going to be important. A fixed mount is great for larger boats that have the ability to hold a larger and heavier fish finder.

Smaller boats such as kayaks and cones do best with smaller fish finders. Portable ones are ideal. Look for a removable munt so you can take it with you when you need to go inside.

Vessel Specific Fish Finders

We touched on this in the earlier section. Vessel specific fish finders usually depend on what type of boat you have and also what type of fish finder you have.

Larger fish finders do well on larger boats. Where smaller fish finders do well on smaller boats. However, a portable fish finder can be used on any sized boat. Making them very versatile.

The display is crucial in ensuring that you can actually see what you want to on the screen. Having a screen too small is going to impair you visually so it can be difficult to locate fish and structure.

Look for something large enough for your style of fishing. Also, ensure that it works well in direct sunlight and in low light conditions. Fishing is done in low and bright light. You need your screen to work in all conditions.


Most frequencies on fish finders are going to be between 15KHZ and 200 KHZ. While the majority of fish Finders will usually be somewhere between 50KHZ and 200KHZ.
