DESCRIPTION

SEIKO's spectacular dive computer is a combination of cutting edge electronics, materials and design made from Titanium alloy and the finest materials. The computer its self is sophisticated but very easy and intuitive to use, even the most in experienced Notrox diver will get to grips very quickly with is functions, yet there's enough depth to the functionality to keep any Pro the right side of the red line keeping your sport Fun and Safe.

Bob our resident dive master and Red Sea warrior rates this product very highly, "It looks a tad expensive on paper but once you see the NX you can see its construction, its light years ahead than the cheaper tin cans on an elastic band products, Yeah it doesn't have every fancy function under the sun but its confidence in the product I want, when this watch says STOP you better listen."

The SEIKO Diving Computer Cal DH33 is a digital diver’s watch featuring a range of dive computer functions. All algorithms are programmed into it to calculate multilevel diving.

SPECIFICATION

Features
The SEIKO Diving Computer Cal DH33 is a digital diver’s watch featuring a range of dive computer functions. All algorithms are programmed into it to calculate multilevel diving.

• Algorihm
The watch has an algorithm that calculates multilevel diving.
The watches uses an algorithm developed by Mr Randy Bohrer, one of the most distinguished scientist in this field, which expands upon the theories of the so-called Swiss model.

• Dive Functions
The watch is equipped with an auto switch that senses water and activated the dive function.
The diving data is measured automatically while diving between 1.5m (5 ft) and 99.9mm (328 ft), eliminating the need for any button operation.
The residual nitrogen and residual oxygen are indicated graphically for a quick gasp of the current safety situation.

• Altitude Compensation
The watch measures the current altitude automatically calculating the residual nitrogen and other data for the next dive taking into account the altitude change following an air flight or move to high ground.

• Nitrox Diving Function The watch can provide data for nitrox diving.
The percentage of oxygen (FO2) in the gas mixture of your scuba tank can be set for the watch from 22% to 50%.

• Dive Plan Function
No-decompression limits are calculated, automatically taking into consideration the current residual nitrogen and altitude.
This mode is convenient for planning the next dive.

• Dive Log Function
Details of up to30 dives are recorded automatically.
The log data includes date of dive, entry/exit time, dive time, maximum depth, FO2, setting (percentage of oxygen in gas mixture), and residual nitrogen/oxygen at the end of dive.
The measurement units of depth and temperature can be selected from ‘metres (m) and centigrade’ and ‘feet (ft) and Fahrenheit’.

Time Functions
• Time/Calendar Function
Hour, minutes, seconds, month, date and day are displayed.

• Fully Automatic Calendar
The calendar adjusts automatically for odd and even months including February of leap years up to 2050.

• Regular Alarm Function
The alarm can be set to ring once a day at a designated time. Hourly time signal and alarm test functions are also provided.

• Hour Correction Function
When you are travelling around different time zones, the time and calendar of the place you visit can be shown easily with only the press of a button. The time can be adjusted in 30 minute increments, making it available for those areas having a time difference in 30 minute increments from GMT.

Other Functions
• Illuminating Light (Electroluminescent Panel)
Certain materials emit light when voltage passes through them. This phenomenon, know as ‘electroluminescene’ is used to illuminate the display.
With the press of a button, the light illuminates the display for 2 to 3 seconds for easy viewing in the dark.
