Skydiving altimeters calculate the correct altitude by air pressure. Older models use a diaphragm which expands and contracts with altitude. This is connected to a lever and then on to a needle on the front of the instrument. They require no power source.
Newer altimeters have no moving parts and are digital in display. They do however require tiny CR type batteries.
An altimeter determines the height by the difference in air pressure. The higher you go the thinner the air becomes (lower air pressure). A skydiver will zero his altimeter on the ground, and as the skydiver increases altitude the altimeter can determine the distance traveled by determining the difference in air pressure.
You wear an altimeter that tells you how far above the ground you are. When you reach your predetermined altitude you deploy your parachute.
Technically, a harness/container, main and reserve parachute are all that is required. An altimeter, helmet, goggles, gloves, clothes, and shoes are optional.
The qualifications to work at a skydiving center include experience with skydiving to work as an instructor. To work as a person at the front desk, one must have customer service experience.
At least one parachute... sport parachuting requires 2 parachutes, a main and a reserve. Other suggested equipement are a helmet, altimeter and jumpsuit.
It used to be almost every DZ started their students on an analog altimeter. It’s got a dial like a watch face with a needle that rotates to show how high you are. These are less expensive than digital altimeters, but they’re less accurate. It’s pretty hard to glance at your altimeter and see if you’re 300 feet up or 450 feet up.

The main difference between altimeter and cabin altimeter is the place where they take their pressure: Altimeter takes the pressure from static ports, while cabin altimeter takes it's pressure from the cabin.
There isn't one because it is a noun
true altitude at field elevation.
My handheld GPS instrument has a barometric altimeter in it also.
My GPS instrument contains a barometric altimeter.
My wristwatch has an altimeter, which as a backpacker, I find very useful.
