Dive computers are expensive instruments. Some of them have lately taken the shape of watches, fancy enough for their owners to want to wear them on a daily basis. Their steel bodies are still fragiles to dents and scratches. Our protectors can be quickly installed and uninstalled from the computer, without any tool. They bring an efficient protection at a low cost. Shock cords, which are largely used in tek diving, hold securely the protectors to the dive computer.
