Shark Deterrent Black Decal

No – the decals are designed for hard, non-flexible surfaces. Avoid applying to rubber fins, soft plastics, or inflatables.

Use black decals for coloured or darker gear, and clear for white or light-coloured surfaces to match your setup.

Anecdotally yes, we are independently testing our deterrents and plan to publish peer-reviewed research ASAP. Early data and real-world performance are strong.

They’re simple solution, affordable, field-tested, and designed with real-world use in mind. No bulk, batteries or tech required.

Nope. They rely on natural visual deterrence without harming or affecting wildlife.

We believe once a shark is fired up and has made its decision to ambush prey in attack mode and is already charging not much will deter it at that point except a shark cage.
This deterrent is not failsafe and not a shark cage and we do not encourage folks to think of it this way. We believe the eyes can help before this happens, as the shark is conducting its risk assessment and deciding what to attack.
Anecdotally and from what we have seen and experienced we believe the eyes has merit to help to alter the sharks decision to fire up in the first place as it makes its risk assessment of what prey to hit. The aim of the eyes is to hereby psychologically trick the shark into thinking its been spotted, and in turn doubt its attack, altering its choice to rather attack prey that has not seen it and does not realise it is there. In this moment element of surprise is hopefully lost and the sharks behaviour is potentially changed to become more cautious of the object with the eyes, giving you time to get out of the water. We believe the eyes has merit with this initial encounter to change the Sharks behaviour and potentially abort the attack.

It is a common misconception that all sharks have bad vision. Each shark species differ in their visual capabilities, but its our belief that most sharks regardless of their vision still conduct a visual inspection as part of their risk assessment before they fire up to attack. In dirty water we feel this is just done at a closer range. From what we have observed most Sharks don’t just swim around bumping into things and eating random objects without first deciding wether it’s potential prey and lining up the attack intentionally.
Depending on the species, water visibility and light the visual assessment will be made at a differing distance each time. Some scientists believe that the Great White shark for instance has great vision, rods and cones and can see its prey 10-15m away in low light and bad visibility, and may be conducting a visual inspection at this point of distance.

We have not yet tested small vs big eyes and hope to test this in the near future. But from what we have seen anecdotally yes it is our belief that the larger the eye sticker the more effective it should be at helping
to deter the shark.

Due to limited resources and funding limiting us in the early years, offical testing commenced in 2025. As a small private company we are so excited it is now ongoing. Aside from anecdotal testing, we are currently officially testing the eyes on sharks and have conducted 2x trails this year already in 2 differing locations. The shark species we have gathered data on to date are; Lemon shark, Tiger Shark, Tawny nurse Shark, Shovel Nose shark, Black tip Reef Shark. As you can imagine we need to travel with large teams, a ton of very expensive equipment to very remote locations to achieve this so it takes time. We are so excited to bring these results to you as soon as possible as testing continues.

The purpose of our validation trials is to basically test the hypothesis that the Shark Eyes decal alters a sharks behaviour, either in the form of avoidance or deterrence.
The recent trials were preliminary trials that allowed us to test the
methodology and gain initial video footage which has allowed us to tweek and fine tune for future trials.

Findings
In the footage we definitively saw the Shark Eyes decoy change both fish and sharks behaviours – ranging from wariness on approach, sharp changes in direction when contact with eyes was made, to sharks giving a wide berth and fish shoals preferentially avoiding.
The trends seen in the current footage really gives us confidence that our hypothesis is worthwhile trialling further, hopefully gaining enough interactions to have a robust data set to analyse and provide significant results.
Additionally, the amount of data and information being gained by these trials is huge, not only from a shark eyes point of view but for the broader scientific community, being able to conduct this groundbreaking science with sharks is very exciting.

Prior to this the fake eye theory has never been tested on sharks before. It has however been tested on other wild land ambush predators before with positive results for the fake eyes theory. An Australian scientist tested fake eyes against lions on the behinds of cows in Botswana with remarkable results, please click the link to learn more:

Man has been using this ancient theory for years in India against tigers, and native Americans were said to use fake eyes too in preventing cougar attacks.
