Why Use Floats For Fishing 

Using floats for fishing can serve you different purposes. With floats, you can fight a fish, which is their intended purpose. It is also useful when fishing in groups. This way, boaters can control boat traffic.

It will also allow the boat captain to track his dive groups who are not diving in the same spot. Also, when you dive deep into the water, floats can alert the others where you are. Floats are convenient to use as storage for spearfishing gears such as stringers, a pole spear, or even a water bottle. 

Float vs. Speargun Reel

As spearfishing conditions and situations change, so should your method of fishing. Deciding between a float and a speargun reel will depend on the many factors that are changing. Here are some points and notes to help you choose between the two. 

With floats, you can see where the diver is. If that diver is you, they can see where you are in the water, highlighting your safety. Floats can help with fighting fish that are bigger, but they can also be annoying in kelp. It is easier to use a kelp carrot instead of a float in kelp. 

Speargun reels can get jams and tangles, which is an inconvenience to spearos. But they do give the diver the most freedom in the water. They can be useful when spearfishing with many divers or when there are obstacles in the water.

How To Choose

In choosing the best spearfishing float, there is no one-size-fits-all. Choosing will depend on details like your budget and needs. Then, matching them to the available models in the market. As for the size, you will have to consider the types of fish you plan to catch. Larger and stronger fish will need a bigger float.

Hard Floats

If your main concern is durability, go for the hard ones. They are hard-wearing watercraft, which provide superb buoyancy and allow them to take a good beating against the water and still perform well. They are bulky, which will need you to have the physical strength to haul them.

Inflatable Floats

If you want convenience, choose the inflatable ones, as they are more compact and easy to haul and set up. 

Float boards

If you are a DIY- enthusiast, you can make your own float from scratch using a boogie board, a dive flag, and a string line. First, you attach the float line to the board, then add the flag on top, and there you have it- a functional dive float.

How To Use

You need a length of float line to connect your float to the base of the best speargun you own. You need a float line that floats and won’t tangle when you dive. When your float is ready to use, haul it into the water. 

Keep in mind that when the water is calm, you should hold your reel in one hand and let out at least 5 feet of the line. Then, pull your best spearfishing float from behind you. 

When towing the float while entering the water, never push the float in front of you. There are strong waves that will push it back in your direction, resulting in injury. 

If you duck through the tide when you enter the water, let out enough line to allow the float to ride easily over the top. Do not fasten the tow line to your gear or wrap it around your hand too tight to prevent accidents.

Keep swimming until you get to an area with calmer water or until you reach your spearfishing spot. Then be prepared to descend. 

When exiting the water, push the float to be in front of you and won’t get between you and the water movement.

Frequently Asked Question 

Is it necessary to rig your speargun to the float? 

It is not necessary. Some spearos prefer it as this makes it easy for them to find their guns if they lose or let it go while spearfishing. 

Insider Advice

When spearfishing, floats are one of the most important pieces of gear you will need. They help to signal your presence in the water. But if ever you’re exiting the water with your float, you will find that a strong wave is fighting you in pulling the float towards the shore.

Do not try to gain and maintain control. Instead, let the float go. Chances are, you will find it washed ashore.
