eSPEAR, The Worlds First Handheld Shark Deterrent Review


Many people have selachophobia, which for those that don’t know, is a fear of sharks. While you may see many facts surrounding the low likelihood of a shark attack while you’re in the water, an attack is a real threat that you need to prepare for.

Many people have tried to do that in different ways from carrying smells that are going to put off the shark to a sharp implement such as a spear that can be used to attack it while you’re in the water. A lot of these methods though are simply dangerous or ineffective.

That’s where the eSpear can be brilliant as it is a highly effective solution that doesn’t put you or the shark in any danger. It simply enables you to disorientate the shark with an electrical field to deter it from getting too close.

It is a great product and one that has been extensively worked on to deliver a high level of effectiveness. In this review, we will look deeper into how it works, how usable it is and how easy it is to use before looking at how it ranks in some key areas, before giving it an overall rating.



This is a product that is going to help to change people’s perceptions of how safe it is going to be in the water when there is the possibility of sharks. Here we take a quick look at the features that it has before looking at them in a greater level of detail.

User Experience

Usability: When you are scuba diving with sharks it’s important to know how to be as safe as possible. That also applies to surfing and swimming in the water too, as there is always a risk that there will be sharks around in the water.

As we all know, sharks are fast and in no time you could have once in your vicinity where you need to act fast to protect yourself. This product will take a very short time to get going and will help to make you feel safe very quickly.

To use it, you need to slide it out of the handle casing and then fold out the tip of the device. A great aspect of this product is that you don’t need to turn it on as once it is fully extended, it will turn on automatically to give you that electrical field.

That process of opening up the device is very quick and therefore you don’t have to worry about fumbling around with it when a shark is coming closer to you. It’s a device that is very easy to use and you’ll be confident when you have it by your side in the water.

Practicality: Having a shark repellent on you is important if you are going to be diving anywhere that you know the creatures might be. Some work better than others though and this is a genius device that will give you confidence while you’re in the water.

You may feel uneasy trying to defend yourself with an invisible force but it’s one that works very well. Sharks sense their food via electrical signals and what the eSpear does is send out its own signal that disrupts the shark and prevents it from any closer to you.

These signals give the shark unbearable spasms in their nose and therefore they will find it painful getting close to you. The great aspect of that though is that once they are out of range of the device, the pain goes away and there are no lasting effects and therefore the shark is unharmed.

It’s a great solution to a long-standing problem. You might feel uneasy about not having something physical to defend yourself but it has been proven to work and therefore it’s not something that you are going to have to worry about, even if you are very scared at the time.

Usage: There are two ways that you would be able to store this device as it comes with a carabiner for easy attachment to yourself but there is also a holster too that you can buy as an additional extra, should you feel the need to use it. Both of these methods will give you instant access to the device.

The battery has a long life and has between 1-2 hours on continual use, depending on aspects such as the temperature of the water. It’s not a product you are going to be continually using though, just when a threat is present, and therefore that battery will keep you protected for a long time.

It has an easy to read battery indicator to let you know when you should get out of the water and recharge your device. Recharging is very easy though and it can be charged via induction to prevent you from even having to plug it in.

Due to the nature of the product, it will be able to be attached to most wetsuits and it can be ideal for surfers, swimmers, and divers to ensure that they are protected. It’s a product that you hope you’ll never need but one that will keep you safe in the water.


  • Highly effective
  • Simple to use
  • Doesn’t harm marine life
  • Long-lasting battery
  • Lightweight
  • Can be securely attached
