OLU 120 snorkelling observation buoy blue

The clips on the sides can be used to attach several OLU 120 buoys side by side. Stay together, keep an eye on the kids, or simply enjoy the experience together, thanks to this small, easy-to-use accessory!

The OLU 120 is available in 3 sizes: Why? The users stay on the top to observe, so several sizes are necessary to be in the best position to observe, depending on each person’s size. Therefore the size depends on the user’s weight. Size S: For a weight less than 40 kg Size M: For a weight between 40 kg and 65 kg Size L: For a weight over 65 kg

Depending on its position, the sun may cause some slight reflections in the viewing chamber. No need to panic. Just use your hands to create some shade, and you can carry on observing.

Size S: weight < 40kg - 430 grams. Size M: 40kg < weight < 65kg - 520 grams. Size L: 65kg < weight - 610 grams.

The Olu 120 is covered with a transparent film that offers a clear view, without deformation. To make the most of it for longer, take good care of it! Avoid anything that could scratch or cloud the film, like sand, stones, sunbathing cream or other abrasive or greasy products.

The air circuit prevents condensation from forming in the Olu 120, but small patches of condensation may appear on the top of the bubble, especially when getting out of the water. Don’t worry. Once back in the water, the condensation disappears. All the walls reach the temperature of the water and the condensation evaporates.

The OLU 120 is inflated in two steps for two reasons: - first, to limit the formation of condensation. This is where the OLU 120 is innovative, because it has an air circuit that prevents condensation from forming when being inflated. - second, for your safety. If one of the chambers is accidentally punctured, the second one is still there to support you. The large black valve at the rear is used for quick and easy deflation.

The Olu 120 is a new way of snorkelling. This DECATHLON invention makes snorkelling much easier. The Olu 120 is an inflatable product that allows you to observe the seabed without putting your head underwater, while remaining supported by an inflatable structure. Snorkelling becomes more convivial: with your head out of the water, you can move, talk and chat, while still observing!
