What Types Are Available?

Portable Fish Finders

Often a fish finder can be quite an unwieldy device. Many products come with different parts which can make setting them up and taking them off a real hassle. On the other hand, portable fish finders are very easy to carry around. When installed, they are self-contained, they run on batteries, and the transducer is attached to a suction cup. That way you can start finding fish in a matter of minutes.

Portable fish finders usually consist of a few pieces which make them stand out. But, using two different parts doesn't mean that you have to sacrifice quality or space. This is possible with systems that have quick attaching mechanisms. That way you can connect devices with head units or ones that come with a separate transducer. Some transducers even attach to the end of your fishing rod and go underwater.

Portable fish finders sometimes need to be connected to the bottom of your boat. But, even if that's the case, you can do it with an attachment system that doesn't require screws or drilling of the hull. This way of installing fish finders is ideal if you don't own your boat or don't want to damage your vessel.

Fish Finders With GPS

Having a fish finder with GPS can make a huge difference. If your fishing trips are on big lakes, for example, and getting lost is easy, then you'll be glad to have a way to know your exact location. Besides that, with a GPS fish finder, you'll be able to keep track of all your favorite places to fish at.

First of all, you should take a look at what kind of maps come with the device you want to buy. Maps come in different forms, but all in all, they let you know where you are and where you're going. Another important thing to consider is getting a GPS fish finder which offers upgrades and updates to its software. One more thing to be aware of is a unit's accuracy. You will want to know where you are within a dozen or so feet.

Finally, a GPS-ready device is going to be either internal or external in its form. If you buy one that has an external unit, you will need to attach it to your boat. Attachment can be a problem if you own a smaller boat or need a portable fish finder which doesn't need installation.

Fish Finders For Kayaks

When it comes to making a kayak fish finder, manufacturers take into account specific conditions. One of which is a profound lack of space in comparison to a regular boat. A person who is in the market for kayak fish finders needs a light, waterproof and sturdy unit. These help to find fish without leaving owners worried about damaging their device. A kayak fish finder also needs to be light, so it doesn't make rowing harder.

One more thing to consider is choosing a device that will mount on your kayak with ease, a device that doesn't need external parts. With such a small vessel, a transducer made for installation on the outside can cause problems.

Another thing to think about is whether you will need GPS. Getting lost on a kayak can happen to anyone in large bodies of water or unfamiliar places. That's why knowing your exact location and where you are going can make a huge difference. After all, you are relying on your strength when out fishing in a kayak. When in a kayak staying on course is crucial; you won't be able to start a motor when you get tired.
