Disadvantages of Console Dive Computers

While console computers offer excellent integration and value, they also present certain limitations that may impact your diving experience, particularly regarding accessibility and convenience during dives.

Less Convenient Readability

Reading a console computer requires locating and positioning the console, which can be cumbersome during dives. The console typically hangs from your regulator system, requiring you to bring it up to eye level for reading. This process takes more time and effort compared to simply glancing at your wrist, potentially disrupting your diving flow or buoyancy control.

Bulkiness Compared to Wrist Models

Console systems add considerable bulk to your regulator setup, creating more drag underwater and requiring additional space in your gear bag. The larger size can become problematic when traveling, particularly on airlines with strict baggage weight limits. The bulk also means more items to manage during your dive, which some divers find distracting.

Limited Accessibility During Dives

Console computers can be difficult to access in certain diving positions or when wearing bulky exposure suits. If the console gets tucked behind equipment or caught in gear, accessing critical information becomes challenging. This limitation can be particularly problematic during technical dives or in emergency situations where immediate access to dive data is crucial.

Diving Conditions and Preferences

Your choice between wrist-mounted and console computers should align closely with your typical diving conditions and personal preferences. Different diving environments and styles favor different computer configurations.
