This is a pretty poorly worded question!! Advantages of Scuba over what? One advantage is you dont drown! Bit more info needed to answer this one!
the better question would be WHY would you want to go SCUBA diving in Birmingham UK? it's over 100 miles to the nearest 'ocean'????
Belt drives can be used when the distance between two shafts(for transmitting power) is large and are relatively cheaper than gear drives.
If you have not dived for over a year or more, it is wise to get a refresher's course known as a Scuba Review to go over your skills.
The cost to start scuba diving can vary depending on where you are, but typically you will need to budget for training courses, which can range from $200 to $1000, and equipment like a mask, snorkel, fins, and a wetsuit, which could be around $300-$500. Overall, you may be looking at an initial investment of around $500 - $1500 to start scuba diving.
In 1950, scuba changed from primarily breath holding to just underwater scuba, technological advances in the 50's create the bathyscaphe, which reached a depth of over 13,000, and Jaques Cousteau was introduced to the American public and spurred interest in scuba diving.
Monofins can have advantages in swimming efficiency for freediving. Monofins are also commonly used in underwater orienteering, a scuba based sport where fast swimming is essential. However, divers in this sport hold the scuba tank in their hands in front of them, not in a harness on their back like a recreational scuba diver. When the tank is worn on the diver's back, it interferes with the traditional monofin's function in a way that tends to negate the fin's advantages. Furthermore, a traditional monofin will induce body pitching that will sometimes result in the diver getting hit on the back of the head by the tank valve. A new type of monofin that uses a hydrofoil instead of the traditional flexible fin blade has succeeded in solving these issues and can be used with standard scuba equipment. Little to no body-pitching, and very efficient thrust production solve the monofin issues with scuba and provide advantages over bi-fins for swimming speed and reduced air consumption. See here the DOL-Fin X-15 monofin being used with scuba. See the related link for further information.
over ur dick sou can have 3 way
It is called the passing gear.
No.
The main advantage that automatic cars have is the ease of which one can learn to drive in them. However, it takes a lt longer for changes in gear to take effect.
they must come over the pressure
