Aqualung Dive Computers

Aqualung Dive Computers — Trusted Technology for Every Dive

Aqualung has been at the forefront of dive computer development for decades, with their range covering everything from entry-level wrist computers for open water divers to the feature-rich i770R, which is among the most capable recreational-to-technical computers on the market. All Aqualung dive computers connect to the free DiverLog+ app via Bluetooth for post-dive log syncing, settings management, and dive data sharing. The entire current range uses rechargeable lithium batteries — no more hunting for replacement cells between dive trips.

At DiveCatalog.com, we carry the full current Aqualung computer lineup: the flagship i770R (available with and without wireless transmitter), the i330R, the i300C, the i200C, and the i100, along with Aqualung wireless transmitters for air integration. DiveCatalog.com is an authorized Aqualung dealer — every computer carries the full manufacturer warranty.

The Aqualung Dive Computer Range

Aqualung i770R — The Flagship

The i770R is Aqualung's most advanced dive computer — and it's one of the most complete wrist computers available for recreational and recreational-technical diving. The headline feature is its ultra-bright TFT color display, which delivers exceptional clarity in all lighting conditions including low visibility and direct sunlight. Three stainless steel push buttons navigate an intuitive menu structure that most divers master without referencing the manual.

Air integration is available via Aqualung's wireless transmitters — the i770R supports up to four transmitters simultaneously, enabling multi-cylinder monitoring for technical and sidemount configurations. Aqualung's patented Gas Time Remaining Algorithm provides real-time gas management calculations that account for depth and consumption rate rather than just showing remaining pressure. Audible alarms and an LED warning light trigger on safety-critical conditions.

A 3-axis full-tilt digital compass with bearing lock, reciprocal heading, and declination adjustment is built in, along with four operating modes: Air, Nitrox, Gauge, and Free Dive. The rechargeable lithium battery charges via USB in approximately 1.5–2 hours. Bluetooth connectivity enables the DiverLog+ app integration. Once you pair an Aqualung transmitter with the i770R, the pairing is permanent — no re-pairing required between dives. Available in black.

Aqualung i330R — Best Value in the Range

Aqualung describes the i330R as their best-value computer, and the specification backs that up. It features a bright color display that remains readable in direct sunlight, a rechargeable battery, Bluetooth connectivity to DiverLog+, four operating modes (Air, Nitrox, Gauge, Freedive), and three-gas nitrox switching. Two-button navigation keeps operation simple. It's the ideal choice for advanced recreational divers who want a capable, connected color-screen computer at a more accessible price than the i770R.

Aqualung i300C and i200C — Connected Mid-Range

The i300C and i200C are mid-range wrist computers offering Bluetooth connectivity, rechargeable batteries, and four dive modes. The i200C includes audible alarms and LED warning lights. The i300C adds a history mode that records your last 24 dives on the computer itself. Both are well-suited to recreational divers who want connectivity and a reliable instrument without the full feature set of the i330R.

Aqualung i100 — The Entry Computer

The i100 is Aqualung's simplest computer — single-button operation, Bluetooth connectivity, and a clean, readable display. For new divers getting their first personal dive computer, the i100 delivers the essentials in the most straightforward package possible.

Aqualung Wireless Transmitter

The Aqualung wireless transmitter pairs with the i770R and i470TC for hoseless air integration. It attaches to a high-pressure port on your first stage and sends real-time cylinder pressure and gas time remaining data to the computer. Sold separately — contact us to confirm compatibility with your computer model.

DiverLog+ App

All current Aqualung computers — i100, i200C, i300C, i330R, and i770R — connect wirelessly to the free DiverLog+ app (iOS and Android). After each dive, open the app and sync your computer: your dive log, profile data, and settings transfer automatically. You can add location, notes, photos, and dive buddy information directly in the app, and share your dives to social media.

Frequently Asked Questions — Aqualung Dive Computers

Do Aqualung dive computers have rechargeable batteries?

Yes. All current Aqualung computers — i100, i200C, i300C, i330R, and i770R — use internal rechargeable lithium batteries. The i770R charges via USB in approximately 1.5–2 hours. No coin cells or AA batteries required.

What is the Gas Time Remaining Algorithm on the i770R?

Aqualung's Gas Time Remaining (GTR) Algorithm provides real-time calculations of remaining dive time based on actual gas consumption rate and current depth, factoring in decompression obligations. It's more accurate than simply displaying remaining tank pressure because it accounts for breathing rate and depth rather than assuming a fixed consumption rate.

How many transmitters can the i770R support?

The i770R supports up to four wireless transmitters simultaneously. This makes it practical for sidemount diving (two cylinders), or technical diving with stage bottles. Once paired, transmitters don't need to be re-paired between dives.

What is the difference between the i330R and i770R?

The i770R adds: an ultra-bright TFT color display (sharper and brighter than the i330R), wireless air integration capability (up to 4 transmitters), a 3D full-tilt digital compass with bearing lock, audible and LED alarms, and the Gas Time Remaining Algorithm. The i330R offers Bluetooth, color screen, 3-gas nitrox, and rechargeable battery at a lower price — a strong value proposition for divers who don't need air integration or the enhanced alarm system.

Are Aqualung computers nitrox compatible?

Yes. The i330R supports three nitrox mixes; the i770R supports nitrox mixes within its four operating modes. All current Aqualung computers support enriched air nitrox diving.

What app do Aqualung dive computers use?

The DiverLog+ app, available free on iOS and Android. It handles dive log syncing, settings management, profile viewing, location tagging, and social sharing for all Bluetooth-enabled Aqualung computers.

Can I use an Aqualung dive computer as a freediving computer?

Yes. All current Aqualung computers include a Freedive mode as one of their four operating modes.
