Sherwood Amphos is the first dive computer made by Sherwood Scuba, which supports diving with double-nitrox mix. For the 1st mix we may set FO2 up to 50% and for the 2nd - up to 100%. This feature gives the user possibility starting diving with technical mixes (excluding Trimix, of course) and grow as a technical diver.
Amphos was designed with standalone digital wrist watch functions. It looks a bit bigger than usual wrist watch, but it sits very comfortable on your wrist during everyday wearing. And it is very favourable thing for those guys who needs watch and dive computer functions in one sleek body.

Like in most dive computers that have standalone digital watch functionality, Sherwood Amphos is designed with 4 buttons user's interface. They are big enough and comfortable to press even in thick gloves.
Display is divided into 3 sections: top, middle, bottom. Viewable area is large to show all necessary data by displaying big and sharp digits.
Dive computer has two bar graphs to display nitrogen loading/oxygen toxicity and ascent rate:
Before diving, we will program certain dive mode and all related to it desirable parameters. Dive computer has 4 Set Groups:
Sherwood Amphos dive computer has Dive Planner that works for ranges 9-57 meters. If I plan repetitive dives - planner will calculate available NO-DECO time according to my nitrogen intake, oxygen toxicity from previous dives, and surface interval.
This Sherwood dive computer inherited all the best features from Wisdom 2 & Wisdom 3 user interfaces and menu sets. They are logically structured and followed one after another. We didn't find even slightest issues with setting this instrument.
Sherwood Amphos: Diving With Air & Nitrox
As a dive computer, Sherwood Amphos operates in 3 modes:
Amphos starts selected dive mode at the moment when it senses depth of 1.5 m, if diver set wet activation to ON.
Dive computer has main and alternative displays with all information related to type of dive, No-Decompression or Decompression conditions, also it warns the diver with Deep and Safety Stops (if set to ON before), and any violations that he/she may have. Also diver may switch mixes during the single dive with the easy procedure.

To access alternative displays whether you are in NO-DECO/DECO modes, at Safety or Deep stops - press A-button for less than 2 sec. To see Mix Switch preview display - press M-button for 2 sec, and to activate backlight - press L-button. User interface in this Sherwood dive computer is very user friendly and easy to learn all button combos.
Scuba dive computer displays Dive Time Remaining (DTR) by monitoring your current depth, oxygen accumulation, No-Decompression status. It shows you not only your DTR at certain depth in minutes, but also displays status on NiBG by adding or taking away segments and O2 saturation (if set for Nitrox dive) on O2BG (NiBG and O2BG - the same bar graph that is shared between nitrogen and oxygen conditions).
When you dive with compressed air – you have 79% of nitrogen and 21% of oxygen approximately. If this is the case – your tissues absorb nitrogen and Dive Time Remaining (DTR) is shown according to nitrogen loading.
If you need to switch between gas mixes – it is easy to do – just use combination of M-button (Mode) and S-button (Select) buttons. Mix switching can be done only from Gas Switch Preview screen, which can be accessed from Dive Main display by pressing M-button. Sherwood Amphos has one of the easiest gas switching procedure around multigas dive computers.
Decompression mode starts when a diver exceeds theoretical No-Decompression limits of time and depth. If this happens – Sherwood Amphos activates an alarm, and all 5 segments on NiBG are filled up and flashing, UP Arrow icon will flash too, and you will see big DECO notation on the lower section of the display.
Below is an example of main DECO mode display:
Also, if diver makes any violations (ascending shallower than required and stay there for some time) – Sherwood Amphos will turn corresponding violation mode and show information related to each kind of violation with appropriate values, Bar Graphs, icons, and graphics.
Sherwood Amphos: Diving In GAUGE Mode
If scuba computer set for GAUGE Mode – it will work as a depth gauge and timer and does not perform calculations for nitrogen and oxygen accumulation, and it will be locked to this mode for 24 hours if dive in Gauge mode was completed.
Below is a representation of information from main and alternative displays, related to GAUGE:
Sherwood Amphos: FREEdiving
As dive computer may be used for freediving activities, you need to set some specific parameters for this sort of diving:
In a Freedive mode Sherwood Amphos works as a depth gauge and nitrogen calculation is based on the default FO2 of Air and the amount that you may have after previous dives from the last 24 hours.
Below is a representation of information from main and alternative displays:
Freediving has its specific displays and set of alarms, like:
If nitrogen intake increases to Deco level and all 5 segments are filled up – you will have audio again and computer enter Violation Gauge mode for 24 hrs.
After the Transition Period of 10 minutes I had an access to the following data and modes:
Sherwood Amphos: What Divers say
We were pleased using and diving with Sherwood Amphos. It inherited only the best things from all range of Sherwood dive computers! It has everything that just spot-on inside one stylish and robust package! I worn it as a wrist watch between dive sessions, going to local cafe-shops and tennis courts. It wasn't bulky, and gave me a sensation of being ready to jump into water right away!
All set up process went smoothly - user interface and manuals were perfect. I loved large display with all essential data shown, and extra info was easy to call up. Switching gases was easy to perform as well.
Number of features on this dive computer related to its price is pretty great! I think Amphos will take place as a favourite for recreational divers, and not only experienced, but for the starters as well.
I liked that this dive computer is capable of being customized for different diving situations and it is a big benefit for those guys who want to dive different scenarios, like air and nitrox, or gauge and freediving, and at the same time it provides us with everithing to keep us safe!
If you are a beginner in scubadiving or experienced recreational diver, and you need a reliable, robust, solid, stylish multitasking dive computer with standalone wrist watch functions, and at the same time you need to save money - I definitely recommend Sherwood Amphos dive computer as your buddy!
