Regarding the difference between recreational diving and technical diving, there is actually no absolute answer to this question. Different people have different understandings of this issue. If we do not consider the purpose and the commercial situation for the time being, and according to the restrictions, and the method of behavior to distinguish, it will be relatively clear.
Recreational diving:
Recreational diving is defined as the use of oxygen or high oxygen (up to 40%) for no-decompression diving with a maximum depth of no more than 40 meters. In infiltration diving, you need to dive in areas where there is natural light injection or where the total length does not exceed 40 meters. This usually means that with relatively simple equipment (single cylinders and regulators), it can quickly rise to the surface in an emergency and does not require complicated training. Due to its simplicity, it is particularly suitable for a wide range of people.
Technical diving
Unlike traditional recreational and business diving and search diving, it is further defined as more nature. Technical diving more than 40 meters above, need to stage decompression, in the closed space more than 40 meters away from the water surface, use 40% -100% pure oxygen for accelerated decompression, and use different gas mixtures in the dive. Technical diving extends the theory of diving methods, technical theory, and training to deal with and manage increased risks. So this usually means using relatively complex equipment to dive in situations where the problem of decompression cannot be raised directly to the surface. It also means diving in an environment where it is not possible to rise directly to the surface of the water because the physical conditions do not permit it, such as shipwrecks or caves. This shows that technical diving requires relatively complex and extended training requirements and has certain physical and psychological requirements. These are technical diving only limited to a small portion of divers.
Technical diving has a broader definition of space than casual diving, and you can define many different forms of diving as technical diving. However, the simple limit of expansion is not technical diving. For example, if you use recreational diving equipment and behave in a manner that drops to 50 meters, diving is not technical diving. It can only be called silly.
Flower Rack
Flower stands are designed as a kind of shelves and intended as an elegant stand for flowers grown not only indoors, but also on porches and balconies. They come in numerous designs – high or low – in a variety of styles, richly decorated or with strict minimalist lines, and they contribute to the appearance of every room. Flowers and plants make a room more inviting, comfortable and add freshness to the decor. However, when indoor plants and flowers become too many, homeowners are faced at the question how to arrange them in such a way so that to enjoy their beauty, but not overload the space? The obvious answer is to get a flower stand which will allow you to display your flowers and save valuable living space.
Flower stands can be designed either as a separate vase for home plants or as a composition which accommodates a miniature garden. Flower stand ideas differ in shapes, sizes, height, width, color and material. You can choose from classic designs, as well as unusual and original models. It may be a single stand for a pot with flowers or a stand for several pots. The advantage of a flower stand compared to any other furniture pieces is that it can help you to arrange the flower pots at different levels, combining them so that the larger flowers do not overshadow the smaller ones.
Typically flower stands are used to organize the pots in a vertical installation and the largest plants are placed on top while smaller plants are arranged at the lower levels.modern-flower-stand-design-ideas-modern-home-accessories-plant-stands-ideasDespite the fact that flower stands are not considered as the most important furniture pieces they often are an accent in the interior or exterior designs. For example, wrought iron options will perfectly complement the interior of a bedroom or living room and, at the same time, will look good as an element of the garden or patio decor. Wooden designs also perfectly fit into the interior and can be used in almost any style – from rustic, Provence, Shabby chic to modern, contemporary and minimalist.
