What is the Best Portable Fish Finder?

Regular vs. Portable

A portable fish finder can get to places a regular fish finder cannot get to. If you can’t permanently mount one to a boat or don’t want to, portable options are a great way around this.

They are great if you are using a small boat, taking on trips or if the boat you are using isn’t yours. A portable fish finder affords you greater flexibility when you are fishing.

You don’t need to worry about the kind of boat you are in, and there is no reason to go to the trouble of mounting it. You can jump in your boat and get going right away, and portable options are often much cheaper.

Regular Vs Portable Fish Finder

Portable versions are great if you are going to be kayak fishing as they afford greater freedom. They are straightforward to use and are perfect for beginners. Our list of portable fish finders reviews will help you find the right one for you.

Regular fish finders used to have better graphics than portable devices, but they have significantly improved over the years. There are also options to have Bluetooth and WiFi connectivity so you can connect with your phone while you are out on the water.

Bluetooth and WiFi options are no longer limited to your larger and more expensive devices, so you can easily connect with your phone and post your social media results.


However, regular fishfinders tend to be larger and therefore have bigger screens. If you are looking for a device with ultimate visibility and screen quality, you will need to look at a regular version.

The displays on portable devices are still good, but a regular fish finder will be the right option if you are looking for a screen with photographic quality. If you will be using your fish finder regularly and have been using one for a while, you may wish to purchase a regular option. (Find the Best Fishfinder GPS Combo Under 1000)

They can be more intricate and a bit harder to use and often come with more options and add-ons than a portable fish finder. Depending on how tech-savvy you are and what you will be using it for will help you decide whether a portable version is right for you.
