Let’s look at one of the most economical and useful accessories available for communicating with your partner while underwater.
Underwater slates are usually made of rigid plastic of different shapes and sizes. They have a built-in anchoring system for the jacket using a clip, or you can carry them in your pocket. They also have a water-resistant pencil and an eraser, although these usually wear out over time and have to be replaced. Erasing a slate is often not very efficient because the eraser can get lost or get the slate dirty if it isn’t of good quality. Another system for erasing while underwater would be to vigorously rub the slate with fine sand. Back above water, you can use any abrasive object like a scouring sponge or a wet cloth, among other things.
The most common models are a simple rectangular slate with two sides for writing, where you can jot down notes while scuba diving, like the marine life you’ve spotted, tips on the point of diving or even a map.
There are even anatomic models for your arm or wrist that often have a number of sides for writing, with a simple and effective elastic band system.
An alternative to traditional slates or tablets is a magnetic slate with an automatic sliding or button erasing system. These slates are a bit more expensive but they are very effective for quick writing and erasing.
Now you’ve discovered a very effective way of communicating with your partner while scuba diving. These slates are highly recommended, and for as little as eight euros you can ensure good communication, more fully enjoy your dives and boost your safety.
