GEO2 Quality, Function and Style. The GEO 2.0 has an upgraded look with a stainless steel accent ring and new color combination – and now includes Dual Algorithm, Deep Stop option and a redesigned user interface with "Step Back" – which allows forward and backward navigation through menus and settings. Additionally, a second Nitrox mix (both programmable to 100%) is available, as well as Firmware Auto-Update which allows the user to download and install operational improvements or even future new features through the PC Interface (with optional cable). A unique combination of quality, function and style, the GEO 2.0 PDC is perfect on its own or as a backup to any dive computer. With Dual Algorithm and optional conservative factor settings, the GEO 2.0 may be programmed to provide no-deco and deco profiles similar to virtually every computer on the market. • Powered by Oceanic's Exclusive Dual Algorithm™ - Your choice between Pelagic DSAT (Spencer/Powell data basis) or Pelagic Z+ (Buhlmann ZHL-16C data basis) • 4 Operating Modes: WATCH (Alternate Time, Chrono, Daily Alarm, Countdown Timer), NORM (Air and Nitrox), GAUGE (with run timer) and FREE (tracks calculations to allow switching between NORM and Free) • User-Friendly Interface with "Step Back" – allows forward and backward navigation through menus and settings • Switch between up to 2 Nitrox mixes to 100% O2 with no restriction (Gas 1 may be up to 100%, and may be less or greater than Gas 2) • Stop times <3 minutes - displays minutes & seconds • Deep Stop with Countdown Timer – Maybe turned on or off. 2 minute countdown at half your max depth, for dives greater than 80 ft / 25m • Single button access to "Last Dive" display (max depth & bottom time) • Data Retention - maintains calculations indefinitely when the battery is changed • Audible Alarm with flashing LED light • 24 dive on-unit log book • History Mode includes total number of dives, max depth, total dive hours, and lowest temp • Optional PC Interface with OceanLog Download and Settings Upload • Firmware Auto-Update: download and install the latest firmware – these may be operational improvements or even new features FEATURES & FUNCTIONS GEO 2.0 Modes of Operation Watch, Norm (Air / Nitrox) Gauge, and Free Dive Push Buttons 4 User Interface Click forward, Fast Scroll and Step Back Mounting Options Wristwatch Activation Water or Push Button Algorithm Basis Dual Algorithm™ Your choice between Pelagic DSAT (Spencer/ Powell data basis) or Pelagic Z+ (Buhlmann ZHL- 16C data basis) Personal Conservative Factor Adjustment Each Level provides No Decompression Limits for the next dive +3000 ft altitude Altitude Algorithm Basis NOAA O2 Limit Basis NOAA Tissue Compartments 12 (5 to 480 minutes) Automatic Altitude Adjustment 2,000 - 14,000 ft Decompression Capability 10 - 60 ft (3-18 m) Deep Stop OPTIONAL - :02 COUNTDOWN TIMER AT 1/2 MAX DEPTH FOR DIVES DEEPER THAN 80 ft/25m Automatic Safety Stop Prompt YES - ADJUSTABLE DEPTH AND TIME Audible Alarm YES - MAY BE DEACTIVATED AND/OR CUSTOMIZED BY USER Alarm Acknowledgment (U/W Deactivation) YES - PUSH BUTTON DEACTIVATES CURRENT ALARM Ascent Rate Range 11-30 fpm / 21-60 fpm Ascent Rate Maximum 30 fpm (<60 ft) 60 fpm (>60 ft) SmartGlo Backlight YES - ADJUSTABLE DURATION Diver Replaceable Batteries YES Low Battery Indicator (Graphic) YES Calendar / Clock DATE & TIME Operating Depth (NORM/FREE) 330 ft / 100 m Operating Depth (GAUGE) 330 ft / 100 m 24 Hour Time to Fly Countdown YES Gauge Mode Run Timer YES Calculated Desaturation Fly Countdown YES Dive Mode Displays MAIN, UP TO 2 ALTERNATES AND 1 SECONDARY High O2 Alarm / Warning 300 SOTU / DOTU High PO2 Alarm / Warning 1.6 DEFAULT OR USER SETTING On-Unit Log Capacity 24 DIVES PC Data Download OPTIONAL PC Settings Upload OPTIONAL Firmware Update OPTIONAL OceanLog Download Memory Capacity 512K** Pre-Dive Planning Sequence PUSH BUTTON 30-190 ft Temperature Display YES Nitrogen Tissue Loading Bar Graph YES Oxygen Loading NUMERIC % Variable Ascent Rate Bar Graph YES No Decompression Time Remaining Display YES O2 Time Remaining Display YES Set Mode with Rapid Advance YES Set Mode with "Step Back" YES Set FO2 Value (%) Gas 1 AIR, 21-100% Set FO2 Value (%) Gas 2 OFF, 21-100% Set Audible Alarm On/Off YES Set Max Depth Alarm YES Set Elapsed Dive Time Alarm YES Set Maximum Nitrogen Tissue Loading Bar Graph Alarm YES Set Personal Conservative Factor YES Set Dive Time Remaining Alarm YES Set Units Of Measurement YES Set Hour Format (12/24 Hour) YES Set Time of Day YES Set Date YES Set Maximum PO2 Alarm YES Set FO2 50% Default YES Set Backlight Duration YES Set Safety Stop Time and Depth YES Set Sampling Rate (OceanLog Download) 1 (Free Dive Mode Only)/ 2/15/30/60 SECONDS Set Digital Gauge Mode On/Off YES Set Water Activation On/Off YES Set Free Dive Elapsed Dive Time Alarm YES Set Free Dive Countdown Timer YES Set Free Dive Max Depth #1 YES Set Free Dive Max Depth #2 YES Set Free Dive Max Depth #3 YES Battery Type CR2430 Battery Life* 300 DIVE HOURS Data Retention (retains calculations indefinitely during battery change) YES Price: £315.00 (Including VAT at 20%) Quantity:
