What is the single most effective way to prevent stepping on a resting stingray?

Using the "stingray shuffle" technique

The most emphasized and effective method for preventing accidental stings from camouflaged stingrays in shallow, sandy, or muddy coastal areas is behavioral modification, specifically employing the 'stingray shuffle.' This technique requires the individual to shuffle their feet along the seabed instead of lifting and placing their feet down. This scraping motion creates vibrations through the substrate which alerts the resting ray to the approaching presence, prompting it to swim away from the area of disturbance before contact is made. Because stingray barbs are often capable of penetrating standard protective footwear like dive booties, relying on this specific movement technique is considered the superior primary defense strategy.
