What are Suunto dive computers used for?
Suunto dive computers are used to plan dive profiles, gases and back-up plans. After a dive, dive information can be downloaded back to someone's computer.
Why can't you and your buddy share a dive computer?
-because dive computers track your dive profile precisely and small differences of even a metre/few feet can affect time limits. -dive computers also track changing nitrogen levels between dives also

How deep can a sub dive?
The deepest submarine is built to go 10000 meters under water. This is so they can go to the bottom of the ocean floor.
How many feet can a uboat dive in 60 seconds?
Most U-boats of WWII were physically capable of diving to maximum depths of around 150-160 feet, although they seldom ventured that deep unless in an emergency. They could attain this depth in approximately 60-65 seconds. Advanced designs in hull reinforcement, mainly pioneered by Germany made this possible. The modern military submarines of today have hull-crush depths of closer to 1,500 feet and that number is growing with advances in technology all the time. These kinds of depths take much longer to reach, depending on dive rate, but can take in the region of 20-45 minutes. (Exact figures are hard to come by, as such information is often classified) Some cutting-edge un-manned submersibles are capable of diving to depths in excess of three times this depth but dive much slower, as their engines are not as powerfull as those of a manned submarine.
How do I control my buoyancy as I ascend after a dive?
release air from your buoyancy vest.
How does a submarine change its depth in the water?
A submarine changes its depth by adjusting its buoyancy through the use of ballast tanks. When it wants to dive, it takes in water into these tanks, increasing its weight and causing it to sink. To ascend, the submarine expels water from the ballast tanks, typically by using compressed air, which reduces its weight and allows it to rise. This ability to control buoyancy enables submarines to maneuver effectively underwater.
How can a scuba diver stay under on compresed air?
A scuba diver can stay underwater on compressed air by managing their buoyancy and air supply effectively. They should use a buoyancy control device (BCD) to maintain neutral buoyancy, allowing them to hover at their desired depth without expending too much energy. Monitoring their air consumption and planning dive profiles according to their tank capacity and depth limits is crucial to ensure they have enough air for a safe ascent. Additionally, practicing proper equalization techniques helps manage pressure changes as they descend and ascend.
Outline three ways to prevent or control most diving problems at occur that the surface?
1. Dive within your limitations. 2. Relax while you dive. 3. Have positive buoyancy at the surface.
When using the recreational dive planner table you should ascend no faster than what per minute?
18 metres/60 feet
How does a submarine move through water?
A submarine moves through water using a combination of propulsion systems and control surfaces. It is equipped with a propeller or water jet for thrust, which is powered by diesel engines or nuclear reactors. To dive or ascend, submarines adjust their buoyancy by taking in or expelling water from ballast tanks. Control surfaces, like rudders and hydroplanes, help steer and maintain depth.
Why is bouyancy control important on the surface plus scuba diving?
Buoyancy control is one of the most important skills you will have to master as a scuba diver. On the surface while entering the water you do not want to be too heavy that you will sink while on completing your dive you have to maintain proper buoyancy control so as not to surface prematurely
Why was it necessary to empty the gasoline from the tanks after Auguste Piccard's dive?
After Auguste Piccard's dive, it was necessary to empty the gasoline from the tanks because the gasoline served as a buoyancy aid during the descent. Once the dive was completed, the buoyancy needed to be adjusted to ensure safe ascent. Emptying the gasoline allowed for greater control over buoyancy and prevented potential hazards associated with the flammable substance at surface pressure. This procedure was critical for the safety and functionality of the submersible after its deep-sea exploration.
When you dive into the water do the bubbles carry you to the surface?
No but they give you added buoyancy.
How can the bends be prevented?
Don't dive too deep. Don't exceed no-decompression limits for the depth you dive to. (limits are available in any of the dive calculating tables) Ascend at a slow pace.
What ship can go under water?
One under the command of Barack Obama. It works just like his plan for economics.
What do scuba divers wear?
Scuba divers typically wear a wetsuit or drysuit to insulate and protect them from cold water, along with a buoyancy control device (BCD) that helps regulate their buoyancy. They also use a scuba tank for breathing compressed air, a regulator to control air flow, and a mask to improve visibility underwater. Additional gear may include fins for propulsion, a weight system for stability, and safety accessories like a dive computer or dive knife.
