Criteria Used for Evaluation

Features

The type of sonar that is available in different portable fish finders will make it possible to find every single fish that is in the water. A dual-band sonar system will make it possible to see both near and far at different detail levels, so that you can have the best view of what is going on underneath you, helping you catch more fish than ever.

You’ll also need to look into the angle of the sonar. You can find options that are up to 120 degrees, which will give you an incredibly wide view. Most will be somewhere in the middle of the range, but depending on how deep the water you are fishing it is, you will be able to make the best decision.

Use

When it comes to fishing, there is a slew of different gadgets and tools that you need to bring with you in order to have the most effective and successful fishing trip possible. While some people are perfectly fine hitting the open waters with nothing more than their pole and some bait, there are other folks out there who prefer to be a bit more prepared when it comes to embarking on the fishing trip of a lifetime.

Why is this though? When talking about fishing, people take on this hobby for a couple of big reasons. One, the simply enjoy the peace and quiet that comes bundled with going on a fishing trip. Two, they are out there to catch as many fish as they possibly can, either for sport or need. These are two very different schools of thought, and if you are someone who just likes fishing for the peace and quiet that it brings, you may not be entirely concerned about catching a boatload of fishing when you take your boat off the dock and into the water.

Durability

Fish finders are some of the most useful tools out there when it comes to fishing gear, and is also one of the most recognizable as well. Along with poles, boat motors, bait, and more, fish finders are one of the most essential tools that you can buy if you want to be the very best at fishing. This isn’t something that guarantees a great day of fishing, but it can go a long way in helping you scope out there very best spots in your area that you should be positioned at if you want the best chance possible to catch as many fish as you can in a small amount of time.

However, one of the biggest downsides to portable fish finders is their need for a constant power source. While this might not seem like that big of a deal right off the bat, if you put some thought into it, it could quickly turn into a bit of a hassle. For starters, if you’re on a smaller boat or something like a Kayak, you may be without a power source at all on your boat. If this happens to be the case, you’ll need to purchase a marine battery and construct your own DIY method of powering the portable fish finder of your choice. And, if you do have a power source on your boat, you need to ensure that the cords of the fish finder will be able to reach it in a way that won’t get in the way of your fishing. Either way, you look at it, there’s some level of inconvenience that is involved.

Effectiveness

It is vital that you are able to easily detach your fish finder and put it on and off without having to make major changes to the boat. When you are on a kayak, there won’t really be a way to install it permanently, which can be a problem for you. Quick Release options are the most common here, but you can find a variety of ways that companies figure out how to make it easier than ever. When you are on a kayak, you will no doubt have a shortage of space that you will have to deal with. All of your equipment will already be weighing down your kayak and you’ll have plenty of other things to take with you. When it comes to a fish tracker, every little bit of weight will make it harder to paddle, making you work harder, and make you more tired at the end of the day. A portable fish finder will be lightweight, compact, and make sure that there is simply one less thing to think about when you are out on the water and hunting the next big catch. Since you will be able to sneak around the water in a way like never before, you will see why kayaks are very great choices for fishing.
