Show off your dive computer in town!
Let’s try using a dive computer and see how useful it can be.
Some dive computers can also be worn as everyday watches, so choose one with a design and features you like,
and wear it around town.
If you have a friend who is interested in dive computers, take them to the beach for the weekend—
and show off your dive computer while introducing them to diving.

How to read a dive computer
Check your dive computer display during the dive.
Unlike a dive table, your dive computer shows your available no-decompression time in real time.
As you ascend and remain at a shallower depth, it displays the no-decompression time available at that depth.
For example, even if it shows 10 minutes of no-decompression time at 20 meters, the displayed time will increase as you ascend and your depth becomes shallower.
