It does the job a first computer needs to do, it does it on a big 2.1 inch screen you can actually read, and it runs for up to 50 hours of diving between charges.\u003c\/p\u003e\n\u003cp\u003eIt is not a cut-down toy. Under the hood it runs the same Bühlmann ZHL-16c algorithm with gradient factors that Garmin uses across the Descent range, it handles nitrox up to 40 percent, and it has proper scuba, apnoea and gauge modes. What you give up against the dearer Descents is air integration, colour, multi-gas switching and the smartwatch features, and for a lot of divers that is exactly the right trade.\u003c\/p\u003e\n\u003cp\u003eGarmin also builds the housing and bezel from 100 percent recycled ocean-bound plastic, which for a dive computer feels like the right place to start.\u003c\/p\u003e\n\u003cdiv class=\"product-info-box\"\u003e\n\u003ch3\u003ePre-order: expected in stock 21 December 2026\u003c\/h3\u003e\n\u003cp\u003eThe X10 is Garmin's newest Descent.

Why pay it?\"\u003c\/h3\u003e\n\u003cp\u003eFor the screen and the battery. A 2.1 inch display with large digits and a proper backlight is far easier to read in UK visibility than a small segment screen, and 50 hours of dive time on a rechargeable battery means no coin cells to replace. You also get Garmin's dive app and NDL Aware, which most entry computers do not have.\u003c\/p\u003e\n\u003ch3\u003eCan I dive nitrox with the Descent X10?\u003c\/h3\u003e\n\u003cp\u003eYes. It supports nitrox from 21 to 40 percent oxygen with PO2 up to 1.6. It dives one gas at a time, so it suits recreational nitrox rather than technical decompression.\u003c\/p\u003e\n\u003ch3\u003eDoes the X10 have air integration?\u003c\/h3\u003e\n\u003cp\u003eNo. It does not read tank pressure.
