Diving usinga motorized underwater tug is a real adventure. Devices in this category provide not only a significant gain in speed of movement. In the course of a single dive, you can see a lot more than it does with a swim with a standard set of equipment.
A short digression into the history
Буксировщик подводный разработан в 60-х годах last century. The idea belongs to the Italian military engineers Elios Tosca and Teseo Tesei. The first samples of underwater scooters were considered as tools that allowed individual fighters to stealthily approach the enemy ships that were on the roadstead or stood at the pier.
Initially, the underwater tug was known bythe definition of "slow motion torpedo". However, due to insufficiently unstable buoyancy in the water column and difficulties with control, the development was called the military only as a "pig."
The prototype represented a rather cumbersomea design that had the shape of a torpedo with several seats for the crew. The latter was delivered to the place where the military operation began on the ship, after which it was submerged. The driver and the miner, dressed in wetsuits, sat on such a watercraft on horseback, reached the enemy vessel, secured an explosive substance on board and committed sabotage. Quite often, the military had to leave such a tug at the site and get to the shore by swimming.
What are modern diving towers?
The underwater towing vehicle looks like a miniaturetorpedoes. This watercraft is driven by an electric motor. At the rear of the structure there is a propeller. On both sides of the body contains the handle. They contain buttons for starting and stopping the motor, as well as controllers for changing the speed of movement. The buttons are made in the form of plates, on which it is convenient to press even if the hands are dressed in rather thick rubber gloves.
How to move on the underwater tug?
Swimmer lowers equipment for divingwater Then takes a horizontal position and grabs the handle of the device. Next, the engine starts by pressing the corresponding button. The device begins to tow the diver. Changing the direction of movement is carried out by the same handles.
Benefits
What are the advantages of underwater towingdiving time? First of all, the scooter will allow you to swim longer distances without the expense of physical strength. Even if there is no desire to move far from the point of immersion, with such equipment you will be able to see more of the interesting things on the seabed.
Underwater scooter towing gives the opportunitysurvey vast areas. Its use will allow you to find any object of interest in a particular area. In particular, if the object of interest is a sunken ship, the scooter will save a lot of time and effort that will be spent on its inspection.
Diving tower looks perfectsolution for people with physical disabilities. If limited capacity makes it difficult to swim freely, the underwater scooter will always come to the rescue, providing movement.
Such diving equipment contributes tolonger stay under water. Due to the lack of physical stress on the body during such heats, oxygen from cylinders is consumed much more slowly.
What dangers await divers using tows?
There are several potential hazardsoperating an underwater scooter. One of the main ones is the risk of decompression sickness when a significant speed develops in the water column or as a result of lifting too fast from depth to surface.
Another problem is limited chargebatteries. Floating too far, the diver may be faced with a problem associated with stopping the engine due to lack of energy. At the same time it will be quite difficult to return back with heavy equipment.
Some modern towers are capable ofreach speeds of up to 6 km / h. When moving at such a pace, the diver may tear off the mask under the influence of oncoming water flows. Therefore, when using an underwater scooter, you need to be attentive and act rationally.
Applications
Underwater tug can be used as inas a useful and entertaining vehicle. Initially, such devices were operated exclusively by professional divers. At present, they are actively used by the military, who unnoticeably overcome considerable distances with their help, transport ammunition, heavy equipment, and large items under water.
For peaceful purposes, underwater scooters are used by archaeologists that work on the seabed. Their exploitation is resorted to by cavers, who are engaged in the study of underwater caves.
Popular underwater tugboat sea doo oftenused during filming. It enables operators to move heavy equipment, in particular, underwater cameras, while maintaining a stable speed.
In the field of entertainment tugboats are operateddivers. Such equipment allows scuba diving lovers to enjoy diving from picturesque reefs without the need to expend their own energy.
