Suunto D4i Dive Computer – with USB
RM665.00
Compact Suunto dive computer with USB cable included — RGBM algorithm, air/nitrox/gauge/freedive modes, 80m depth, optional wireless tank pod integration.
The Suunto D4i is a compact wrist-mount dive computer aimed at recreational divers who want a slimmer profile than the Zoop Novo without sacrificing capability. It runs Suunto’s RGBM algorithm across air, nitrox (up to 100%), gauge, and freedive modes, depth-rated to 80m. Optional wireless air integration is available via the Suunto Tank Pod. The D4i is smaller and lighter than the D6i — a better fit for divers with smaller wrists or those who want less bulk on a liveaboard. This version includes the USB cable for connecting to Suunto DM5 software for detailed dive log analysis on PC or Mac. Good choice for recreational divers progressing toward nitrox certification who dive the reefs of Tioman and Perhentian regularly.

Love the comfort of the Suunto D4i strap. Is it available in multiple sizes to fit different wrist sizes?
Junhao Lo –
Thank you for sharing your thoughts on the comfort of the Suunto D4i strap, Axel. The D4i does indeed come with a soft, comfortable silicone strap for a perfect fit. Regarding strap sizes, Suunto’s D4i strap is one-size-fits-most. However, for users who find their strap too loose or too tight, a Suunto strap adjuster is available as a free accessory. Would you like me to look into this further or share more information about the strap adjuster?
Lucas Tham –
Is there a limited lifetime warranty on the Suunto D4i dive computer? And how well does it handle water pressure underwater?
Imran Hanafiah –
Thank you for reaching out with your questions, Lucas. The Suunto D4i Dive Computer comes with a commercial-grade design that meets military standards for depth, pressure and shock. It has a guarantee which covers two years from the date of purchase for any defects. However, please note that it is not a limited lifetime warranty. As for handling water pressure underwater, the Suunto D4i is designed to withstand water pressure up to 120 meters. It’s a rugged device that’s built to withstand the demands of scuba diving. If you have any further questions, feel free to ask.

The Suunto D4i seems like a solid product for scuba diving, although I do wish the battery life was longer. Still overall a great device that has helped me track my dives with ease!

The Suunto D4i seems really easy to use for scuba diving and freediving. Can I connect it wirelessly to my smartphone for more advanced tracking features?
Junhao Lo –
Hi Alicia, thank you for sharing your positive experience with the Suunto D4i Dive Computer! The device does support wireless connectivity via Bluetooth to your smartphone. By pairing it with a Suunto mobile app, you’ll be able to access advanced tracking features, customizable watch faces, and even customize alerts and reminders for easy dive planning. Simply download the free Suunto Diver app (available for iOS and Android) and pair your device to get started.

Really curious, what are the chances of getting water inside the device after a dive? Is it a sealed unit?
Junhao Lo –
Thank you for reaching out about the Suunto D4i Dive Computer. The device is designed to be a sealed unit, preventing water from entering the unit during normal use. The computer has a series of seals and gaskets around the buttons and screen to ensure a watertight seal. However, if the device is used in extreme conditions or if there is a high degree of physical stress on the unit, it’s possible for water to enter the device. Our tests have shown that the Suunto D4i can withstand a pressure of up to 200 bar, but we still recommend regular maintenance and inspection of the device to ensure its water-tight seal is intact.

I completely adore my new Suunto – it’s a game-changer! The freedive mode is so easy to use, I’ve already mastered it after just one dive. Very lightweight and exactly what I needed. I paired it with a wireless dive computer and I’m absolutely loving every feature it has to offer. Definitely worth the investment!
