Galileo SOL is the first scuba dive computer that has integrated system for monitoring diver’s pulse. This feature made it possible to calculate tissue loading not only by taking into consideration temperature, altitude, breathing ratio, but also heart rate, and estimate workload and decompression schedule for additional safety.

As I've mentioned before, Galileo SOL can monitor our heart rate during diving. For this purpose it has special POLAR sensor and belt included in the package. To make it work properly, we need to wear this thing around the chest and enable specific monitoring function during set up.

I think I won’t be wrong by saying, that we got an ultimate dive computer when UWATEC introduced to scubadiving market Galileo SOL. It has taken its well-deserved place in high-tech dive instruments line along with Oceanic OC1, Mares Icon HD, Suunto D9, UWATEC Galileo Luna and many other excellent specimens of the dive gear and would keep it for many years to come!

UWATEC Galileo SOL is a high-tech dive computer and suits best to advanced and technical divers, but if you a beginner and serious about diving – prepare yourself to study thoroughly manuals, not just skip from page to page. This dive computer has huge number user adjustable features and before you change or adjust certain setting you need to have deep understanding of what you are doing!

Likewise Galileo Luna, Galileo SOL scuba dive computer has 3 control buttons and 3 types of display layout: Light, Classic, and Full.

Amount of dive data displayed depends on chosen type of display, for example, if you choose Light configuration – SOL will maximize the size of display and digits accordingly and show us only crucial dive data.

Also Light display configuration is not supported during Decompression, Microbubble (MB) Level stops, and diving with multiple gas mixes. Galileo Sol will swap Light display to Classic layout automatically, if you have above-mentioned conditions.

Galileo SOL has 2 bar graphs: Nitrogen Loading Bar Graph, which is shared between Nitrogen Loading and Ascent Rate Bar Graphs, and Oxygen Toxicity Bar Graph that is shared with Tank Pressure Bar Graph. Brief descriptions of them I wrote below:

  1. Nitrogen Loading Bar Graph shows graphically nitrogen intake by adding and subtracting segments, if you have full set of segments – No-Decompression dive becomes Decompression dive;
  2. Oxygen Toxicity Bar Graph is a graphical representation of oxygen toxicity level and it works the same – adding and subtracting segments – with full bar you will get a High O2 alarm;
  3. Ascent Rate Bar Graph – graphically shows how fast your ascent is; if it is faster than allowed maximum – Ascent Rate Bar Graph is displayed instead of Nitrogen Loading Bar Graph, and dive computer gives you an audio alarm and warning message in inverted colours







Many adjustable settings of UWATEC Galileo SOL are similar to original (without firmware upgrade) Galileo Luna dive computer, except probably following functions below:

  1. enabling multi-gas mix – Predictive Multi-Gas (PMG) must be set to ON;
  2. enabling usage of 3 transmitters;
  3. setting FO2s for 3 Nitrox gas mixes;
  4. setting workload estimation type: Heart or Respiration monitoring and corresponding adjustments of those types


Below I summarized functions that can be adjusted according to your needs:

  1. FO2 – Air, 21% - 100% for 3 Nitrox gas mixes;
  2. Dive parameters: MB Level – L0, L1 – L5; Safety Stop Timer; Reset dive computer; PO2 – 1.2 – 1.6 bar, etc.
  3. Warning settings – this sub-menu allows to turn ON/OFF warning messages individually (but alarms can not be silenced or turned off!);
  4. Digital Compass and Altimeter;
  5. Clock parameters: time format and time; alarm and date, etc.
  6. Utilities: IrDA speed, backlight duration, gas integration, etc.
  7. Personalization settings: configure display, language, workload estimation – choose between Heart and Respiration monitoring, etc.
  8. Dive Planner – allows us to plan No-Decompression and Decompression dives;
  9. Logbook – view our previous dives;
  10. Pictures viewing and uploading them from PC via optional IrDA interface and SmartTrak software


Dive Planner of Galileo SOL works the same way as Dive Planner of Galileo Luna dive computer, and besides, in this dive computer, it will plan for using multi-gas mixes.

We may program our No-Decompression (No-Stop) and Decompression dives with the same manner as we do in Galileo Luna:

  1. For No-Decompression dive we enter desirable depth and Galileo SOL will calculate corresponding No-Decompression (No-Stop) time at this depth;
  2. For planning Decompression dive we need to enter bottom time and dive computer will show appropriate deepest stop depth and stop time and total ascent time


Dive Planner uses FO2 and MB Level that you set before, water type and altitude, temperature, nitrogen and oxygen absorption, and workload estimation to calculate No-Decompression and Decompression dives.







UWATEC Galileo SOL: Diving With Air & Nitrox

Diving with Galileo SOL – it is all pleasure. We set it for Nitrox and planned our dive, chose display layout for Classic; we have paired our transmitter(s) – looks like we are ready to go underwater. Just do the last checks before…

Dive computer has all information it needs to make our dive safe, enjoyable, and very informative! It calculates No-Decompression Limits (NDLs) according to many data including unique thing - Heart Monitoring System, it receives tank pressure data from wireless transmitter and shows us appropriate Remaining Bottom Time (RBT) regarding of how much air we have left in tank in use and our breathing ratio and if RBT or pressure is low Galileo will warn us with appropriate alarm.

Galileo SOL has all set of alarms and warning messages to keep us fully aware about any diving situation we may get in!

It gives an alarm when O2 level is too high and warns us about exceeding maximum operational depth (MOD), it warns us about fast ascent and low tank pressure, Galileo SOL wake us up when we are about to enter into the Decompression mode and if we missed Decompression or Microbubble (MB) Stops…

I may continue with the alarms and warning messages that this remarkable dive computer has on offer for us for about 1 more page! But I think – that’s enough to see that we have in our hands very sophisticated and really user friendly dive computer, and that is not only regarding to its interface, but also thanks to its safety features that made this dive equipment really unique!

If we exceed No-Decompression limits (NDLs), Galileo SOL will warn us that we are about to enter Decompression mode and after entering decompression all dive data will be calculated according to Decompression dive.

Dive computer gives us warning by inverting colour of the background of that part of display where it shows Deepest Decompression Stop depth, Decompression Stop Time and Total Ascent Time. Also you will get full set of segments on Nitrogen Loading Bar Graph.


For our additional safety Galileo SOL has Microbubble Level Stops.

If you set MB Level higher than L0 (this setting doesn’t require ‘level stops’), you will be prompted to complete few ‘level stops’ no matter whether you are in No-Decompression mode or in Decompression mode.

For MB Level Stop this dive computer has specific display that looks similar to Galileo Luna display, besides that is shows your Heart Rate (here I listed only values relative to MB Level Stop):

  1. level depth;
  2. level countdown timer;
  3. Total Ascent Time;
  4. corresponding icons and notations


If diver decided not to do ‘level stop’ – dive computer will automatically adjust preset MB Level to lower one and if you dive deeper after that, Galileo SOL may give you a request straight away to complete ‘level stop’ to reduce the risk of microbubbles formation.


UWATEC Galileo SOL: Diving In GAUGE Mode

In Gauge mode dive computer doesn’t perform any decompression and MB calculations and all alarms are switched off, except Low Battery Alarm. SOL can be used as a depth gauge and timer only.

Display looks similar to Galileo Luna screen with one more value displayed – heart rate:

  1. current, average, and maximum depths;
  2. Elapsed Dive Time (EDT);
  3. tank pressure;
  4. heart rate;
  5. temperature;
  6. time of the day;
  7. ascent speed value (while ascending)


You will be able to use Stopwatch functions, make a Bookmark, Switch to different gas mix, and use a compass as well in Gauge mode.

There is one more possibility to use Galileo SOL for freediving after upgrading firmware from UWATEC website free of charge.

Back to Top







At the post-diving stage when we are on surface on took off our dive gear with POLAR belt all together – we are probably ready to use other functions of this dive computer, like:

  1. Dive Planner – to plan our next consecutive dive;
  2. Viewing pictures;
  3. Review Logbook and Dive Statistic (History) – there is one difference between Luna and SOL logbooks – Galileo SOL has one more page for display diving profile graph with Heart Rate graph all together; if you set Heart Monitor to OFF before – this page will not be displayed;
  4. Upgrade the firmware and upload settings to Galileo SOL from PC by using SmartTrak Software

You may store for up to 100 grey-scale bitmap pictures in Galileo SOL on-unit memory and view them either on surface or underwater. For this purpose we need to have SmartTrak installed on our PC. This software is pretty amazing stuff – we are able to set variety parameters and then upload them to SOL – it means that we may set our dive computer directly from our PC!

Dive Logbook is very extensive and has 6 pages of dive data, and Dive Statistic (History) will show you longest and deepest dive, total number of dives and total time spent underwater, etc.

Galileo SOL has Data Retention function that means – we may replace battery and all calculations and dive data will remain safe in dive computer nonvolatile memory (NVRAM).

As I mentioned above – there is firmware upgrade available and it is Apnea & Trimix.







UWATEC Galileo SOL: What Divers Say


  • easy to set and read data after learning manual;
  • huge display - easy to see data in any conditions;
  • digital compass - perfect addition;
  • smooth gas switching procedure;
  • additional safety features for cautious diver;
  • dive computer with plenty of functions and does everything for you;
  • works perfectly for recreational and technical diving, and is recommended dive computer for serious divers



  • manual is not an easy one;
  • IrDA (infrared PC interface) unit is optional...


As we read all info and our reviewers’ opinions we may conclude that we have very reliable and very multifunctional dive computer here!

To have full advantage of all features and functions, we must set aside quite a time to learn and play with Galileo SOL, because it is high-tech dive equipment and requires persistence and patience from us!

Galileo SOL and Galileo Luna dive computers are very similar, except presence of Predictive Multi-gas function and Heart Rate Monitoring system in Galileo SOL (basic firmware).

The first function allows us to set SOL for 3 different Nitrox gas mixes and enables Switch gas mixes during a dive, which gives us greater flexibility during diving and decompression; and the latter function – adds more safety for workload calculation by monitoring our heart rate – that may be great benefit for diving in challenging conditions or in high altitude!

From my side, I may tell, that I always had perfect signal either from heart monitoring sensor or air-integrated transmitter – no doubt about that! Display has high contrast and all audio – alarms and warnings are perfectly heard underwater.

And I reckon that Galileo SOL suffers from the lack of Dive Simulator (such class of dive computer must have dive simulator for better learning and refreshing knowledge after long non-diving interval), and would be nice to have separate Adjustment Modes – one for beginners (in order not to change some settings that may be critical), and other for professionals.

It would be nice to have kind of electronic ‘help’ for certain settings stored in on-unit memory as well.

Other than that – no complains anymore!

Galileo SOL is a perfect dive computer and it is a MUST if you are serious about diving, and it is worth all money to the end! So, if you love high-tech dive gear and your budget allows you to invest in something very unique – go for Galileo SOL ! I know that you won’t need another dive computer for many years to come!

Tank pressure not showing before the dive

I just spoke with Jason at Leisure Pro, a distributor of the SOL computer.

He researched it. The tank pressure should show before the dive.

Either your setup was non standard or something is wrong with the pairing. Check through the owners manual and see if you can figure it out, if not get in touch with the folks at Scubapro. They will be happy to advise.

Galileo SOL Doesn't Show PSI In Tank Until I Hit The Water

When i hook up first stage and turn on air - it doesn't show psi in tank. I have tried with water contacts on and off. I have tried to get it wet and still noting. It will come on when i get three feet down.

Every Dive Galileo SOL Gives Me Only Positive Emotions!

SOL has large and perfectly readable underwater display, many user-adjustable settings, extra safety features, like dynamic calculation of micro-bubble levels. I have never lost my wireless and I have always known my remaining bottom time. I can very easy check buddy's tank pressure if I want to.

PC infrared interface is much better than data cable - my Galileo SOL always has steady connection with PC.

I may add on top of that multi-gas support, heart rate monitoring and perfect PC software SmartTrac that I downloaded from UWATEC website without charge.

I didn't do firmware upgrade for freediving, so can not comment on this.

User manual is quite lengthy and I had to read it few times before I got a bit familiar with user interface and computer operations.

I used to have Suunto Cobra and Aeris Elite before, but UWATEC Galileo SOL - it's something out of this world!
