The Perdix 3 has a dedicated Freediving Mode with configurable sampling rates and customisable vibration alerts — for example, a distinct vibration every 30 seconds and a different pattern every 10 metres, so you can receive critical information without looking at the screen. It also features Shearwater's most powerful vibration motor, making it well-suited for freediving.

It uses a standard AA battery that you replace yourself without tools. It ships with an Energizer Ultimate Lithium AA (recommended), which gives up to 60 hours of dive time. If that runs low on a liveaboard, any AA battery from a local shop will work in a pinch. Vibration functions require either a 1.5V lithium or a 3.7V rechargeable lithium cell.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails class=\"mds-faq\"\u003e\n\u003csummary\u003eDoes it connect to a smartphone app? \u003cspan class=\"mds-faq-chevron\" aria-hidden=\"true\"\u003e\u003csvg viewbox=\"0 0 10 6\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"1.8\" stroke-linecap=\"round\" stroke-linejoin=\"round\"\u003e\u003cpolyline points=\"1,1 5,5 9,1\"\u003e\u003c\/polyline\u003e\u003c\/svg\u003e\u003c\/span\u003e\u003c\/summary\u003e\n\u003cdiv class=\"mds-faq-body\"\u003e\n\u003cp\u003eYes.

It also adds faster Bluetooth, enhanced security features (encrypted firmware, optional PIN protection), improved menu navigation, and the ability to save three independent settings profiles. For anyone currently using a Perdix 2, the display alone makes it a compelling upgrade.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails class=\"mds-faq\"\u003e\n\u003csummary\u003eWhat dive modes does the Perdix 3 support? \u003cspan class=\"mds-faq-chevron\" aria-hidden=\"true\"\u003e\u003csvg viewbox=\"0 0 10 6\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"1.8\" stroke-linecap=\"round\" stroke-linejoin=\"round\"\u003e\u003cpolyline points=\"1,1 5,5 9,1\"\u003e\u003c\/polyline\u003e\u003c\/svg\u003e\u003c\/span\u003e\u003c\/summary\u003e\n\u003cdiv class=\"mds-faq-body\"\u003e\n\u003cp\u003eAir, Nitrox, 3-Gas Nitrox, OC Tec (trimix \/ multi-gas), CC\/BO (closed circuit rebreather with bail-out), Gauge, Freediving, and Avelo (unlock code required).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails class=\"mds-faq\"\u003e\n\u003csummary\u003eDoes it have a digital compass? \u003cspan class=\"mds-faq-chevron\" aria-hidden=\"true\"\u003e\u003csvg viewbox=\"0 0 10 6\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"1.8\" stroke-linecap=\"round\" stroke-linejoin=\"round\"\u003e\u003cpolyline points=\"1,1 5,5 9,1\"\u003e\u003c\/polyline\u003e\u003c\/svg\u003e\u003c\/span\u003e\u003c\/summary\u003e\n\u003cdiv class=\"mds-faq-body\"\u003e\n\u003cp\u003eYes — a 3-axis, tilt-compensated digital compass is built in and displays directly on the dive screen.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003ca href=\"https:\/\/www.mikesdivestore.com\/blogs\/mikes-london-dive-store-blog\/shearwater-perdix-3-everything-you-need-to-know-about-the-best-new-dive-computer-of-2026\" title=\"Shearwater Perdix 3 Blog | Mike's Dive Store\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0283\/6108\/files\/Perdix_3_1.jpg?v=1780397090\" alt=\"Shearwater Perdix 3 Blog\" style=\"margin-right: 0.015625px; margin-left: 0.015625px; float: none;\"\u003e\u003c\/a\u003e\u003c\/div\u003e\n\u003ch5\u003eWhy Buy From Mike's Dive Store?\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAuthorised Shearwater Dealer\u003c\/strong\u003e — We're an authorised UK dealer, which means your computer comes with full manufacturer warranty and support.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGenuine Diver Expertise\u003c\/strong\u003e — Our team are active divers.
