Hose type

A flex hose is flexible and comfortable in use. A rubber hose is a little less flixible. The SPG without a hose either needs a hose, or, alternatively, can be mounted in the high pressure port of the 1st stage, directly.

PC-interface

The PC-interface lets you transfer the data from your dive computer to your PC or laptop. This way you can create and update a digital logbook. The software can be downloaded from the manufacturer’s website.

Hose length

The standard length of high pressure hose is approximately 80cm. A shorter hose of 56 cm, 20 cm or 15 cm, is often used with stage bottles.

SPG

These instruments (minimally) consist of an SPG

Power source

With an eco-drive a battery change is not necessary

Air integrated

With an air integrated function on your computer, you can view the cylinder pressure. The pressure is transmitted by the transmitter or by the high pressure hose connected to the dive computer. With some computers it is possible to connect several transmitters to one computer. I.e. when you dive with several different gas blends.

Compass

These instruments (minimally) consist of a compass

Digital compass

With a digital compass on your dive computer you’ll be able to navigate underwater and will not need the analogue compass any longer

Nitrox

Suitable for use with Nitrox with an oxygen percentage higher than 40%

Battery

Many dive computers allow you to change the battery yourself. Even though doing it yourself may seem simple, we recommend that you have the battery changed at your local dealer, whom subsequently will also do a pressure test to make sure your computer is waterproof again. Rechargeable batteries can be charged with the provided cable.

Dive mode

A bottom timer is a depth guage and timer in one. The freedive mode measures the same as the bottom timer, however it measures in seconds. The air mode is the standard dive mode. The nitrox mode allows you to dive with a higher oxygen %. Trimix is a blend of oxygen, nitrogen and helium. And the rebreather recycles part of the gas that you have used.

Display

A regular screen consists of digital stripes which show the details on the screen. A dot-matrix screen consists of smaller pixels, which makes the visability better because of a higher contrast in the screen. A full colour screen has the best visability.

Planning mode

With the planning feature on the computer you will be able to preparer for your planned dive and you’ll be able to see how long you can stay at various depths

Switch gasses

The gas switch feature allows you switch gas blends during a dive. I.e. when you are diving with Nitrox 32% and would like to do a safety stop with Nitrox 50%.

Personalise display

A dive computer that is adjustable to personal settings will allow you to adjust the settings and where information is shown on the screen. With some computers you can even adjust the size of the font

Software update DIY

These computers allow you to run firmware updates yourself. However, with most computers, to run the firmware updates, you will need the PC-interface

Glass type

Saffire glass is harder than mineral glass and also is less prone to get scratches

Waterproof to

100 meter = 10 Bar = 10 ATM
