A new dive computer should solve a specific problem: easier reading, tank-pressure display, a different battery arrangement or functions that match your training. This list covers rectangular screens, compact watches and a hose-connected format. It separates buying priorities from the published review scores shown on individual product pages.

How we chose and ordered these picks
Recreational screen and control choices lead, then air integration and more specialist capability. More modes do not automatically earn a higher position.
List position is an editorial recommendation, not a review score. The selection uses the documented features and limitations below. We have not personally tested this equipment. Verified publisher scores, where available, are shown separately and link to their evidence. Our catalogue is still being researched; inclusion does not mean a product has a completed scored review.
The shortlist at a glance
Choose a model to jump to its details. Compare the exact configuration before ordering.
A rectangular dive computer built around a 2.2-inch colour LCD and two-button controls. Air, nitrox, three-gas nitrox and gauge modes cover its core functions; vibration alerts and wireless charging keep the interface straightforward.

Compare with the Peregrine TX if wireless tank pressure or an integrated compass matters. The standard Peregrine does not offer those features. Check screen readability on your wrist before choosing a smaller watch format.

A transmitter is optional equipment: check the bundle before budgeting. Compare the larger display against the smaller Tern TX; both offer tank-pressure integration, but their shape and screen technology differ.

The Element III, model IQ1101, is a wrist computer with a backlight, audible alerts and a user-replaceable CR2450 battery. TUSA lists nitrox support, water activation and dive, gauge and watch modes. Its published log capacity is more than 500 dives, and a console version is a separate buying choice.

What to check
Check button access and screen readability before comparing it with larger colour-display computers. Verify the exact IQ1101 model and manual: Element II and other TUSA computers are not interchangeable evidence. Battery replacement must follow the manufacturer procedure, including seal care and checks.

This Aqua Blue version of the EON Core is a compact colour-screen dive computer with a rechargeable battery. Suunto lists connectivity with its app and Tank POD pressure transmitter. The display-and-battery combination is its main distinction from watch-style computers such as the D6i Novo.

What to check
Check whether a Tank POD is included and which firmware and supported dive modes are installed. A compatible transmitter and a phone connection solve different jobs. Plan how you will recharge on a trip, and compare readability on your own wrist rather than assuming a colour display suits everyone.

The Perdix 2 is a rectangular dive computer with a 2.2-inch colour display, titanium bezel and piezoelectric buttons. A user-replaceable AA battery, vibration alerts and support for four wireless pressure transmitters are its practical distinguishing features. This is the Perdix 2, not the original Perdix or the newer AMOLED Perdix 3.

What to check
Check the supplied battery type, compatible transmitters and package contents before comparing prices. DiveOtter’s review describes the screen material differently from Shearwater; the specification here follows the manufacturer’s aluminosilicate-glass description. Do not choose advanced diving modes solely because a computer provides them.

What to check
Confirm the supplied hose, connection, operating modes and complete manual. Configurable settings require understanding; they are not a shortcut to a suitable dive plan.

Before you buy
Read the display at arm’s length and operate it with gloves.
Confirm gas modes, algorithm settings and training requirements before changing computers.
Budget for the correct transmitter if wireless pressure is a reason to upgrade.
Take two or three suitable models from this list into a comparison, then remove any that fail your fit or compatibility checks. A lower position here can still be the better purchase for your setup. Check the product page for source dates and unresolved details before placing an order.
Does air integration remove the need to understand gas planning?
No. It displays pressure information; it does not replace gas planning or training. Follow the complete equipment and backup requirements for your diving.
