Saving Your Precious Time And Finding The Best Dive Computer For You
Dive computer reviews are perfectly organized and consist of fully researched information and ratings of Aeris, Cressi, Mares, Oceanic, Sherwood, Suunto, Tusa, and UWATEC/ScubaPro brands. In Catalogue Section you may compare any models side-by-side and select dive computer according to your needs! Join thousands of happy customers!
If we compare Gekko and Zoop – we will find many similarities in display layouts, users’ interface and operations of these two dive computers.
And mainly differences will be only colour scheme and absence of PC interface support in Suunto Gekko, as this dive computer doesn’t have PC download option.
It is still possible to reset calculations for nitrogen and oxygen intake and reset some other functions to the factory defaults, but it may be done only in dive shops with special piece of software that is not sold for private usage.

Suunto Gekko dive computer has 3 operation buttons on the user interface: Smart, Plan, and Time. All of them are located on top side of the unit – it is good for an easy access.
You may see that 2 bar graphs that Suunto Gekko has, work similar to Suunto Zoop, Suunto Vyper and Suunto Cobra dive computers. Below I made a brief description each of them.
Left side bar graph is shared between Mode Indication, Consumed Bottom Time (similar meaning to Nitrogen Tissue Loading Bar Graphs in Aeris and Oceanic dive computers) and Oxygen Limit Fraction (OLF) displays:
Right side bar graph is shared between Ascent Rate, Battery Status, and Logbook Page Numbering:
Setting this dive computer is very easy task and you can do it in no time after getting familiar with Gekko interface and manuals.
Below is a list of customizable functions that can be accessed from Set mode:
All of those settings are similar to Suunto Zoop dive computer adjustments.
If you want to plan your following dive – Gekko has Dive Planner function that allows us to see our No-Decompression limits at range 9 – 45 meters in 3 meters increments in accordance with nitrogen and oxygen absorption from previous dives, if any. This function is similar to Zoop, Vyper and Cobra dive computers.
After we set all of that, we activate Suunto Gekko for desired dive mode and do pre-checks, like appropriate Altitude and Personal settings, alarms, and correct FO2 and PO2 values. If everything is fine – dive computer and you are ready to be ‘buddies’ and go underwater!
Suunto GEKKO: Diving With Air & Nitrox
During dive it is very easy and intuitive to interpret everything on display.

To create a Bookmark of your dive profile – press Plan button and Gekko saves data in its memory and later we may view it.
On the right side of display this Suunto computer has Ascent Rate Bar Graph that is graphic representation of the speed of your ascent. If you ascend faster than allowable maximum – dive computer will give you message SLOW and STOP, beeps and shows all segments on Ascent Rate Bar Graph.
At certain conditions Suunto Gekko may give you Safety Stop prompts.
If we miss Recommended Safety Stop – there will no be penalty time applied, but Mandatory Safety Stop must be completed. Mandatory Safety Stop prompted if you are continuously ascending faster than allowable maximum and it includes 3 minutes Recommended Safety Stop as well.
For diving with Nitrox we have to set exact values for FO2 and PO2 in order for dive computer to calculate all things correctly. After activation of Nitrox dive mode, dive computer will show you entered values and calculated maximum operational depth (MOD), according to FO2 and PO2 you set before - check that everything is correct and if it is – we are ready to test Gekko for Nitrox dive!
Again, the display is similar to Suunto Zoop and I mentioned below only values that Gekko shows us, related only to Nitrox dive:
If you press Time button, Gekko will display Consumed Bottom Time (CBT) Bar Graph instead of Oxygen Limit Fraction (OLF) Bar Graph and current time.
If you exceed your No-Decompression Limits (NDLs) – depth and time – Gekko will activate Decompression mode. During decompression you will be prompted to complete one or few decompression stops at the certain range of depths and all calculations are related to Decompression mode dive.
All dive computers from Suunto family have Continuous Decompression feature, which means that we decompress within the certain range of depths. It starts from the ‘floor’ (deepest depth where deco stop time won’t increase) to the ‘ceiling’ (shallowest depth) and decompression is done between them.
During Decompression mode Suunto Gekko shows us following data and it manages decompression stops perfectly:
Display data is very similar to other Suunto dive computers, so if you are familiar with some of them – reading the display won’t do any troubles for you, and it is very intuitive if it is your first dive computer!
Suunto Gekko is always here to help us to complete decompression safely and if we missed correct decompression ceiling and ascended above it, dive computer would start beeping on us, shows corresponding icons, our current depth and ceiling depth, and Error notation. It means that we have only 3 minutes to correct our position and return to ceiling depth displayed or a bit below.
If we continue to violate decompression in some reason – Gekko will go into permanent Error Mode and will work as a depth gauge and timer only. If you get that - you should stay out of diving for at least 48 hours.
Ok, we are on surface now and it is a good time to look through our logs, history and boast about our underwater adventures to the friends!
Suunto Gekko dive computer has 3 functions at this stage that will be in great interest of you. First one is Logbook, second – is Dive History. Below you will find brief explanations for each of them:
Suunto Gekko, as well as Zoop, doesn’t have an option to adjust sampling rate for dive profile recording – it is factory fixed and it is 30 seconds.
And on top of that, Suunto Gekko doesn’t have download to PC option. But it is possible to reset nitrogen and oxygen calculations and set some values to the factory default by using PC interface data cable and special software. Apparently software is not supposed to be sold for private use. So, it may be considered as an advantage for dive shops and clubs that may give Suunto Gekko dive computers for rent and for group dive training.
Suunto GEKKO: What Divers Say
Suunto Gekko is a very basic dive computer and its functions similar to Suunto Zoop and Suunto Vyper, except it doesn’t support data transfer to PC, and it doesn’t have On-Unit Dive Simulator and user adjustable sampling rate option.
Also Suunto Vyper has backlight adjustable, but Zoop and Gekko have phosphorescent display that means – we need to use dive torch to light up the display.
Everything else – nice and user-friendly as it should be in reliable dive computer made by Suunto!
My opinion that Suunto Gekko is better suitable for dive shops and dive clubs for renting purposes, you may have it for personal use as well as an entry or backup instrument, but we have many other dive computers in nowadays scubadiving market with extra features and slightly dearer, so maybe there is a sense to save 100 – 200 bucks and buy computer with more functions!
But if you don’t mind to have dive computer for personal use without PC download option and without adjustable backlight– there is no problem at all! Suunto Gekko is very reliable dive instrument by all means!
