1. How much is the Underwater propeller?

An Underwater propeller allows anyone who can't swim to gallop in the pool and the sea.There are two trigger buttons at the grip.As soon as he holds hard, the pusher starts to work.You just need to hold the handle and do nothing.The propeller rotation in the pusher generates thrust, which can drive you forward, up to 40 meters deep underwater!Is it very exciting?So how much is the Underwater pusher?

At present, the price of Underwater pusher is between 2000-7000 yuan. The differences, size, materials, brands, etc. of the Underwater pusher can cause price differences.

2. How to choose Underwater propeller

Some underwater pushers are suitable for snorkeling or low depth diving, and some are more suitable for deep diving, technical dives or cave diving.There are many factors to consider to buy a pusher, and their characteristics and how you will use are important.

1. The maximum diving depth is first to be considered. If you plan to dive for 30 meters, then a pusher with a limited depth of 5 meters is not suitable for you.

2,Then you need to consider the battery life and model. If a pusher can only work for 30 minutes, it is not suitable for shore potential.

3. The weight of the pusher is actually very important because you need to move and maintain it on the road.

1. How to stand up on the surfing board

Athletes stand on the surfing plate, or use a water movement that controls the waves such as abdominal plates, Kneeling boards, inflatable rubber pads, rowing rowing, kayaks, etc.No matter which equipment is used, athletes must have high skills and balance ability, and at the same time be good at swimming in the middle and long distances.So how do you stand up on the surfing board in the actual operation?

The surfing movement is the athlete's proling or Kneeling on the surfing plate, and draws the starting point where there is a suitable wave.When the waves are pushing the surfing board to slide, the athletes keep the surfboard standing up in front of the waves, and open the front and back of the legs (usually the balanced legs are in front, control the legs behind).Waves, fast gliding.

2. Why can't the surfing board sink

The root cause is buoyancy.For surfingboards, the value of buoyancy and gravity determines that the surfboard will not sink.

There are two causes of buoyancy:

1. The density of the surfboard itself is less than water. The buoyant caused by the part that is not soaked under the water can offset gravity.

2. The shape of the surfing board determines that it has a larger volume of water (which is related to the slightly rolling of the bottom area and edge), which causes a large buoyancy to offset gravity.If the bottom area of the surfing board is small, there will be no chance to get enough buoyancy.

The pressure is just a manifestation of the effect of the interaction between the surfing board and the seawater, and does not determine the ups and downs of the object.Water's force on surfing boards is buoyancy and not support.If it is supported, it is related to the size of the pressure.

1. How to use Underwater propeller

For us, the underwater world has always been magical, attracting people who explode to explore and watch.The diving sport itself has a strong sense of excitement. It is a project that many people with adventure spirit want to try.During diving, the Underwater propeller is a very important device. Let's see how the Underwater pusher use it!

It is equipped with powerful propellers at both ends, which can generate 17.66ibf thrust underwater, allowing you to keep your visual water resistance and move forward quickly.This propeller does not need to be too complicated. You only need to hold the propeller tightly with your hand to ensure that the propeller does not fall, and the operation is very simple.

At its handle, there are two trigger buttons.

two,Underwater propellerWhy can I bear 10,000 meters of water depth

The pusher of the Underwater pusher uses advanced magnetic coupling driving technology. This technology greatly reduces the impact and vibration of the pusher during the operation of the pusher, extend the life of the pusher, and all electrical components are absolutely sealed in a sealing sealIn the cabin, the risk of seal leakage is reduced.

In response to deep water ultra -high -pressure and strong working environment, the pusher applied a special oil -supply self -compensation structure. On the one hand, the propeller independently overcome the risk of leakage of the sealing cabin in the super high -pressure strong working environment. On the other hand, it also greatly reduced the propellerMaintenance difficulty.The fusion design and precision process of machinery, electricity, and paddle make the product efficiency, noise, and power density of product efficiency, noise, and power density.Excellent overheating protection, overcurrent protection and other functions ensure the reliability of product operation.Special metal surface treatment technology ensures the mechanical strength and salt -resistant corrosion capacity of the product.
