Along with your basic Scuba diving gear trio including regulators, BCD (Buoyancy Compensator Devices), and last but not the least, a Dive Computer.

Dive computers have evolved from big display screen computers to compact wristwatches with LED or LCD screen displays, still doing all the complex dive calculations.

I understand Dive computers TLA (three-letter acronym) or symbols could be difficult to decipher and the dive computer manual guides can be too lengthy to read.

Still dive computers help you to avoid doing all the complex diving table calculations, constantly keeps you updated about your rate of ascending and dive depth to avoid decompression sickness (DCS).

We have enlisted the Best Dive Computer under 300$, which are bestsellers, high performing, and affordable with high accuracy.

Editor’s Review

Oceanic Geo 4.0 is the newest version of Geo range. This is watch size dive computer is more suited for active divers.

Active divers who spend most of their times in or around diving in the waters.

If you are someone fashionable, you will really dig the funky modern perforated strap design with a bright matt color finish.

The time mode is separated from the Dive mode, allowing you to use it full-time on land as a regular wristwatch.

As the battery is user changeable, you will also get battery kit with key.

For easy user experience you also get quick user guide to start with your dive computer.

Oceanic GEO 4.0 is highly recommended for advance level divers.

Do check this video with superb in-depth review of Oceanic 4.0 dive computer.

Editor’s Review

Suunto Novo Zoop has got all the wrist-mounted puck shaped dive computer features you need to start.

It is easy to use with scratch-resistant glass screen.

This Dive computer can be programed for Nitrox mixtures from 21% to 50% oxygen and displays oxygen partial pressures from 17.4 psi to 23.2 psi (1.2 to 1.6 bars).

It also provides temperature readings above and below the surface to 1.5 (1C) accuracy and is altitude adjustable up to 10,000′ (3,000 meters).

Data link port available at side, so you can plug your USB wire to get your previous dives’ data.

This one has got segments section at the top and bottom as well with four navigation buttons.

More intuitive algorithm and bundle of features available. Records all your dives at maximum.

This Suunto Novo Zoop Dive computer is very easy to use and easy to understand different modes.

I would highly recommend it as best dive computer under 300$ for beginner level scuba divers.

Editor’s Review

SEAC DIVER is a win deal for beginner level divers.

It do not comes with a built-in Bluetooth for the sake of extended battery life.

My conclusion is It is one of the best entry budget dive computer in 300$.

The capability are far to expect under this price tag.

Dive log have large capacity, can record upto 500 dive records.

This watch constantly monitors the activities and records.
