Review: Diviac Digital Dive Log, Part III

Sunday, July 12th, 2015

Divers can also access Diviac via tablets, both iOS and Android versions. The features and design of the tablet app are nearly identical to the mobile version, allowing you to transition from one to the other seamlessly, but it’s also perhaps the suite’s biggest disappointment.

The larger screen on a tablet could have allowed for a richer experience, and could have made logging weather info possible. Integrating the fish-card view mode of the browser version’s marine life database could have given the app the feel of a fish ID book; instead, the only real difference is that the tablet app keeps the sidebar menu constantly visible on all menu items except the home screen.

Again, the functionalities of the smartphone apps are all there, and they serve the app well, but nonetheless the tablet apps feel a bit like a wasted opportunity.

Overall impressions and conclusion

Diviac seeks to combine a host of different dive administration tools, with a log as the primary element, as well as a marine life database, a dive-specific social network, and even a travel segment (which isn’t reviewed here, but is essentially a combined dive travel database and search engine). And it manages to do this quite well. Interfaces across all platforms are consistent and easy to navigate.

The real plus here is the easy integration from platform to platform. Being able to log dives on the go is extremely useful for me, but being able to add backlogged dives on my computer is equally useful. And the dive-computer integration adds increased functionality, not only to Diviac, but also to my dive computer. I had never really transferred log data from my dive computer before I started using Diviac.


  • Strong online platform, allowing you to store your dive data in the cloud
  • Smartphone and tablet apps for both iOS and Android
  • Large marine life database, with offline capability
  • Simple, functional interface
  • Integration for photos in each dive-log entry
  • Good, granular privacy settings
  • Verification of dives by buddy or guide
  • Dive-computer integration (premium only)
  • User-generated templates for quicker logging (premium only)



  • Custom numbering of dives not possible, and workaround a little cumbersome
  • Not all dive logging info available on mobile and tablet apps



Diviac is a clear sign that we’ve entered a new phase of digital dive logs. Whereas the first ones were little more than glorified spreadsheets, with logging done only locally and minimal (if any) options for backup, new digital dive logs are cross-platform and cloud-based. This brings all the functionality of the best smartphone apps to your dive log. And while Diviac isn’t the only one on the market, the suite’s seamless integration between platforms, many supportive functions and general ease of use makes it a strong contender. The ability to share dives between buddies and the use of templates is something that may be considered little niceties, but ones that many an experienced diver will greatly appreciate. In my book, that gives it a solid 4.5 out of 5.

Blue Holes

Saturday, November 27th, 2010

Blue holes, physically, are hazardous due to their structure and depth. Their surrounding walls cause bad water circulation, meaning the water is generally depleted of oxygen. Their depth needs specialized training. Nitrogen narcosis will be common. The disorientation which results could lead to divers behaving recklessly and could cause them to remain down longer than the oxygen supply will allow.

Despite these dangers, or maybe due to them, these blue holes are extremely popular amongst scuba divers:

• In Lighthouse Reef, Belize, there’s the Great Blue Hole that’s nearly round and will be all but surrounded by a system of Lighthouse Reefs. The blue hole’s wa lls display stalactite formations that’re angled to permit scuba divers to swim underneath them. Water within this hole will be extremely still. Visibility oftentimes rises up to two-hundred feet. Because of its depth, 145 meters, scuba diving the hole will be solely advised for expert scuba divers, yet the encompassing reef will be great for recreational and novice divers.

• Blue Hole within the Red Sea will be thought to be the more hazardous of the blue holes to scuba dive and has been referred to as the “Diver’s Cemetery.” The danger derives from the tunnel referred to as the Arch, that links the hole toward the open water and will be about 52 meters under the surface.

• The Dean’s Blue Hole will be the deepest within the world. It is located west of Clarence Town within the Bahamas and is 202 meters below the surface. It’s a favorite amongst free divers and within April of 2010, William Trubridge broke the diving world record as he got to 92 meters.

If you are searching for something exotic and new to attempt on your vacation, attempt scuba diving one of these blue holes. Their beauty is rare to visualize and they are thrilling.

Nitrogen Narcosis

Thursday, November 25th, 2010

It’s due to you getting the opportunity to interact with numerous vibrant sea creatures discovered residing amongst the gorgeously formed majestic stones and corals. There’re only a few ideas which you must understand about it so you’ll enjoy fully the exploration as you’re minimizing the risks included with the sport. The compressed air which the tank possesses has a combination of 78% nitrogen and 21% oxygen.

Nitrogen narcosis could lead to an effect almost like liquor intoxication and usually happens at more than 100ft. During this moment, a victim will suffer a lowering within his ability to comprehend things which are occurring around him and judgment ability will additionally be crucially impaired. At this point, he might perform things that must not be performed at all, such as removing his goggles or other vital portions of his diving gear such as his fins or regulator s.

If you view your diving companion showing symptoms of this condition, you need to instantly help him make a controlled rise upward toward the surface, while observing all abnormal behaviors which the companion may show. The symptoms involve decreased dexterity, anxiety that’s manifested within their body behaviors, increased excitability, over confidence in dealing with a crucial situation, and delayed response to auditory or visual prompts.

As you view these symptoms manifesting within your diving companion, or if you begin to sense the exact same symptoms yourself, instantly start an ascent toward shallow waters. As you get nearer to the surface, you’ll see the symtoms and effects slowly dissipate. Following this, don’t attempt to dive in again for the rest of the day.

Nitrogen narcosis could be prevented by remaining within shallow waters. Though 18m might not be your idea of an amusing diving exploration, it’s a safe depth that will prevent this condition from arising.
