Diving with a computer offers which advantage compared to using only dive tables?

• A. It eliminates the need to plan time and depth
• B. It tracks depth and time more accurately
• C. It guarantees no risk of DCS
• D. It is cheaper than using tables

Answer: (B)

The main idea is that a dive computer provides real-time, dynamic tracking of your depth and elapsed bottom time and uses that actual history to update your no-decompression status as you dive. Dive tables are fixed; they assume a specific depth and time profile and don’t adapt if you drift, change depths, or adjust your ascent. A computer continuously analyzes what you’ve actually done and tells you your current allowed limits or warns you if you’re climbing too fast, helping you stay within safe margins. That real-time, depth-and-time tracking makes it more accurate than relying on static tables. It doesn’t eliminate risk or guarantee safety, and it isn’t inherently cheaper, but it gives you up-to-date information tailored to your exact dive pattern.
