Sherwood Amphos

Sherwood Amphos


The Amphos is Sherwood’s newest addition to an already strong lineup of dive computers. Sherwood’s first true watch computer is sure to be a diver’s favorite. This watch computer’s display is based on the intuitive Wisdom3 format.

• Four Operating Modes
• Two Gas (21–50% and 21–100%)
• DSAT Decompression Model/Modified Haldanean (Same algorithm as the Wisdom3)
• Safety and Deep Stop with countdown (Min:Sec)
• Logbook: 24 dives (3 screens each)
• Selectable audible alarms with Flashing icons
• Loading bar graphs (Nitrogen, Oxygen, Ascent)
• Wet activation
• History Mode: Total Dives, Max Depth, Total Dive Hours, Lowest Temp
• Data Retention: Maintains settings and data during battery swap
• Optional: USB Cable Connector



The Sherwood Amphos also has an amazing Freedive mode making it one of the most universal Watch/Scuba/Freedive computers around.


Amphos starts selected dive mode at the moment when it senses depth of 1.5 m, if diver set wet activation to ON.

The Amphos 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.

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).

If you set Amphos for Nitrox – dive computer performs calculations in different way. You have different percentage of nitrogen and oxygen and your body responds differently to such a gas mix. In this case diver is exposed to oxygen toxicity. When amount of time remaining before he/she reaches O2 limits becomes less than No-Decompression (NDC) Time Remaining at certain depth, dive computer starts calculations for that depth regarding to O2 and Oxygen Time remaining (OTR) will be displayed as Dive Time Remaining on the main display.

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.
