As a gear-obsessed diver, the Editor took the newly acquired GARMIN Descent X30 to the Maldives for a real-world test. For someone like me who loves scuba diving but has started finding it a little hard to read small text underwater, the criteria for choosing gear have changed.
Today I want to share why I believe this watch is a true "lifesaver for aging eyes," and how it strikes a perfect balance between price and performance.
Visual Impact: A 2.4-Inch Display That Makes Underwater Data Crystal Clear
GARMIN Descent X30 size comparison with other dive computers
The very first thing that blew me away when I jumped in with the GARMIN Descent X30 was its display. This dive computer features a 2.4-inch color LCD display with outstanding underwater readability.
With my previous watch-style dive computer, the biggest frustration was the tiny text — especially in low-visibility or murky water where I had to strain to focus. The large font and high-contrast screen of the GARMIN Descent X30 completely solved that problem. As I mentioned in the video, it truly felt like I had found my "lifesaver for aging eyes." If readability of underwater data is as important to you as it is to me, this large-display design will have you hooked from the first dive.
Great Value: A Highly Recommended Dive Computer for Around NT$21,990
A significant price difference exists between the GARMIN Descent X30 and the GARMIN Descent Mk3i
Price is often the sticking point when shopping for a dive computer. High-end models on the market can easily exceed NT$40,000–50,000, which is no small commitment for recreational divers.
The GARMIN Descent X30 is officially priced at NT$21,990, landing it squarely in an extremely sweet spot. It delivers GARMIN's signature precise GPS, an electronic compass, and a full suite of dive modes (Air, Nitrox, and Trimix) — all at roughly half the price of a top-tier flagship. If you're not necessarily willing to spend big on the highest-end model, the GARMIN Descent X30 at around NT$21,000 is a highly economical and practical choice.
Intuitive Controls: Four Water-Resistant Metal Buttons and Impressive Battery Life

Beyond the large screen, operability is another strong suit of the GARMIN Descent X30. It uses a 4-button water-resistant metal button layout that is easy to press even with thick gloves on, eliminating the frustration of a touchscreen failing underwater.
In terms of battery life, the GARMIN Descent X30 supports up to 30 hours in dive mode (and up to 47 hours in night dive mode), which is more than enough for short dive trips without needing to charge constantly (though it's still a good idea to bring your charging cable along to maintain healthy battery life). Its casing is made from ocean-recycled plastic and weighs only 160 g, making it very comfortable to wear.
The Best Choice for Recreational Divers
After putting it through its paces in the Maldives, the Editor believes the GARMIN Descent X30 is a perfect embodiment of the word "practical." It doesn't overwhelm you with overly complex or hard-to-understand features, yet it delivers exactly what divers need most — a clear, large display and an accessible price point — to the highest standard. If you're looking for a dive computer that will accompany you on long-term ocean adventures without making you squint to read it, the GARMIN Descent X30 absolutely deserves a spot on your shopping list.
