Sherwood Wisdom 2 is well-known dive computer from the middle of 2000s. Not long time ago it got a new look and Deep Stop function was introduced to improve its performance and bring us more safety. This Sherwood dive computer is air-integrated and can be worn as a console only. We may add a compass to widen its area of applications.

Sherwood Wisdom 2 is a hose air-integrated dive computer with options to add Quick Disconnect (QD) and compass to make a handy Navigational computer console.

This Sherwood dive computer suits well beginners and experienced recreational divers too. It has well-written user manual, easy to read display, and intuitive user interface.

Sherwood Wisdom 2 dive computer is operated by 2 control buttons - Advance and Select. They are quite big and we didn't find any difficulties pressing on them.

Display is devided in 4 setions, digits are big and clearly seen underwater in any dive conditions. Backlight is strong and audio is loud.

To represent some critical information graphically, this Sherwood dive computer has 3 bar graphs - N2BG, O2BG, and ARI. Bar graphs for nitrogen and oxygen loading - N2BG and O2BG are not shared, like in Sherwood Insight and Profile dive computers. ARI (ascent rate bar graph) is located under the O2BG on the right side of the display.

User manual is well-structured and can be easy followed, and dive computer's interface is very intuitive as well, so learning it and become ready diving won't take you too long!

 


 

 


 

 


 

Sherwood Wisdom 2 has similar screens to Sherwood Insight dive computer. We may get access to Data, Plan, Log, History, Dive Simulator, and Set modes. Right now we are interested in following screens:

  • Data screen shows information in accordance with dive mode that we set: Air, Nitrox, Gauge;
  • Plan mode - here we plan our No-Decompression dives. Planner calculates available depths and bottom times according to nitrogen and oxygen exposure from previous dives (if any); Dive Planner works for depths 9 - 57 meters;
  • Set mode - that's where we set our dive computer

Interface is user-friendly and all parameters are easy to enter - this is a great benefit, especially if Sherwood Wisdom 2 is your first dive computer!

 


 

 


 

 


 

When we set Wet activation to ON - Sherwood dive computer starts calculating dive after we submerge to about 1.5 meters and stay at that depth about 10 seconds.

As all other dive computers Sherwood Wisdom 2 is constantly monitoring our nitrogen, oxygen exposure, and air consumption (in the case of air integration). And all of corresponding data of these parameters goes under Dive Time Remaining (DTR).

So, for example, if O2 DTR is more critical for us in certain moment (O2 loading is high) - dive computer displays Dive Time Remaining with O2 icon (DTR display shows us time that is most important for us in particular moment).

 

Sherwood Wisdom 2: Diving With Air & Nitrox

No-Decompression display has 3 screens - main and two alternatives. By pressing Select (S) - side button we may swap them to see any additional information.

Sherwood Wisdom 2 has automatic Safe Stop reminder and Safe Stop display pops up if we ascend to 6 meters during No-Decompression dive below 9 meters. The most important parameters here - Safe Stop Depth and Time. Safe Stop is not mandatory so if we miss it - no penalty added.

As this dive computer come with Deep Stop function, we may set it to ON/OFF in Utilities Set mode. If Deep Stop is OFF - this function won't be activated.

Another two important alarms - High PO2 and High O2.
Dive computer alarms with High PO2 if current PO2 level reaches PO2 alarm set point. Sherwood Wisdom 2 may enter cautionary mode if current PO2 level comes to 0.2 ATA less than PO2 alarm set point.

Cautionary High O2 mode turns when our level of oxygen toxicity becomes equal to 80% of maximum allowable and High O2 alarm comes if we have 100% or even more of oxygen exposure.

 

When I exceeded No-Deco limits, Sherwood Wisdom 2 entered Decompression mode with alarm beepping on me and red LED was flashing. At the same time I saw message DECO-STOP was displayed on top of screen, UP Arrow was flashing and Deco Stop depth and time was displayed.

Sherwood Wisdom 2 monitors our diving for any Deco Violations and if any - it switches appropriate Violation mode, according to situation. It's programmed to monitor Conditional Violation underwater and on surface with corresponding displays and functions, 3 Delayed Violations, and Permanent Violations underwater and on surface.

 

Sherwood Wisdom 2: Diving In GAUGE Mode

Third dive mode is Gauge. In this mode Sherwood Wisdom 2 doesn't calculate No-Decompression times and depths, nitrogen and oxygen loading. It works as a depth gauge and timer only.

After diving in Gauge, dive computer locks for 24 hours and doesn't perform any calculations for nitrogen and oxygen loading, so it is better to stay on surface and away from diving for above-mentioned time, not to get injured.

In Gauge mode only two displays are available: main and one alternative with the examples of dive data shown below:

  1. max and current depth;
  2. Elapsed Dive Time (EDT);
  3. tank pressure;
  4. Air Time Remaining (ATR);
  5. ARI (if ascending);
  6. temperature;
  7. time

 

Back to Top

 


 

 


 

 


 

Plan and Set modes were explained in Pre-Dive Section of this review and now we turn on to the last dive screen that Sherwood Wisdom 2 has - Logs, History, Dive Simulator, and PC interface function:

  1. Last dive screen - it is, obviously, dive data from our last dive;
  2. Log mode has 3 screens and shows dive data our recent 50 dives;
  3. History mode keeps info about 999 total dives and 2999 dive hours;
  4. Dive Simulator allows us to make a virtual dive, and in this case Sherwood Wisdom 2 uses real settings, but without considering tank pressure. It is a great function that gives us opportunity to get familiar with Wisdom 2 and learn it quickly;
  5. PC upload/download function helps us to manage dive computer settings by uploading them using special cable and PC software, and organizing our dive profiles by downloading them to PC

 


 

 


 

 


 

Sherwood Wisdom 2: What Divers Say

Positives

  • good for recreational diving and recommended dive computer for beginners as well;
  • easy to set and operate;
  • user-friendly manual and interface;
  • easy to read display;
  • good value for money

 

Negatives

  • outdated software;
  • high price for dive computer or navigational console

 

I made 10 test dives with Sherwood Wisdom 2 and didn't encounter any issues whether with learning and setting it or using underwater and interpreting dive data, as this dive computer was easy to operate.

Actually it was one of the easiest hose air-integrated dive computers I've ever tried along with Mares Nemo Air! Its big display produced sharp and clear seen digits and I enjoyed intuitive interface and flawless diving procedures, and structure of user manual! And I didn't have problems pressing buttons as well.

Sherwood Wisdom 2 - Convenient & Easy To Read Large Display

I'm using NAVCON, like on the picture above for quite a while. Sherwood Wisdom 2 with a compass is a great recreational dive computer with hose air-integration. Large display is easy to read and very intuitive. All digits are perfectly seen at any depth and angle, thanks to computer's strong backlight. Coloured bar graphs are nice addition to its layout.

Sherwood Wisdom 2 Has Everything That Hose Air-Integrated Computer May Offer

Great NAVCON, basic and reliable. It may work well as a backup dive computer as well.

Large and easy to read display. Sherwood Wisdom 2 does everything I'd expect from a hose air-integrated computer and it is one of the least expensive model with compass and QD on the market.
