Overview
The GS Explorer S (2025) sits at the top of Mibro's outdoor line: 10ATM with a freediving mode, dual-frequency GNSS (L1+L5) across 5 satellite systems, route navigation via GPX/KML/TCX import, and an operating range from -25C to 50C, at a $149.99 official sale price.
What it does well
- Freediving at this price is unusual. 10ATM with a dedicated freediving mode, where most watches under $200 stop at swim tracking.
- Works in real cold and heat: rated from -25C to 50C.
- Dual-band GNSS with route navigation (GPX/KML/TCX import) on a 1.32-inch AMOLED at 466x466 with 1,500 nits.
- 25 hours of continuous GPS and up to 20 days of daily battery; the titanium S-Ti Standard and Premium variants add offline maps.
Tradeoffs to know
- Release year and the military-durability claim are marked approximate in our data.
- Third-party app support was not verified; no supported payment wallet is verified.
- 10ATM with freediving mode is not the same as a dive-computer certification; scuba divers need more.
Price and availability
$149.99 official sale price (list $199.99) from the Mibro store. Prices can change.
FAQ
Can the GS Explorer S really freedive?
It carries 10ATM with a dedicated freediving mode, per Mibro. That covers recreational freediving; it is not a scuba dive computer.
Does it have maps?
The base model navigates imported GPX/KML/TCX routes without a rendered map. Offline maps are documented for the titanium S-Ti Standard and Premium variants.
Which phones work with it?
Both iPhone and Android, through the Mibro app.
