Sun test shows the surface of the water from underneath reflecting the rocks, then sea grass then in deeper water the blue. Our inlays and decals do the same. So no matter what the water colour is or what the bottom is made of the board will match at the time and also match any changes.

This is the most important example of behaviour we observed. As the shark approaches the fish riding in on the wave to gain speed it at about 4m away aborts. Why? The fish are broken up, it would be a perfect time to single 1 out. But it doesn’t. It swims off. We strongly believe from this and other examples that as the wave lifted the fish their body angle in relation to the sun changes and for a split second the reflective scales made them to shark seem to disappear. To the shark the fish are no longer there. No fish no point so it swims on to look for other fish. We have many other examples that have convinced us that if we can not be seen there is not reason for a shark to approach.
Find the shark. Ariel patrols and drones are easy when the water is clear or there's no wind chop and your flying over every 10 minutes. Each summer due to poor water its wasted for days or weeks at a time (we lost most of January one year). So if the water is clear, there's a little wind, its in school holidays and it's just flown over in the past 10 minutes yes you are a little safer. The rest of the time? Better to take shark safety out of the hands of Government and vested interest groups and make your own decisions.
It's vital for total concentration for aerial survey work. Any split second loss can lead to a missed shark and its easy to do. Even with the best conditions, experienced teams and regular patrols the shark that is a risk is unlikely to be seen before the event.
