Review: Un muy buen equipo para bucear, si no te gustan los relojes grandes... este no es para ti . es grande pero es muy bueno.
Review: A dive watch you can wear to work and to the gym. For the price point of a dive watch, it's nice to be able to use it for more than just diving. This watch offers so much data, customizable algorithm and so far, a totally reliable connection (Even though I still dive with a backup SPG and backup computer). I haven't had a chance to use the diver to diver messaging yet, but I'm excited for the first time I go diving with someone else who has this watch. The flashlight is surprisingly useful.

## Features

- Advanced, watch-style dive computer features a stunning 1.4” AMOLED display, scratch-resistant sapphire lens, 51 mm titanium bezel and optional titanium bracelet
- Dive-first design with 200-meter dive-rated case includes metal leakproof inductive buttons and multiple dive modes for recreational to technical scuba diving and freediving
- Enhanced SubWave sonar technology provides the ability to exchange preset diver-to-diver messages up to 30 meters (available with software v.15.70 or later) as well as monitor tank pressures and depth for up to eight divers, within a range of 10 meters when paired with the Descent T2 transceiver (sold separately) for group dive support
- Built-in LED flashlight with variable intensities and strobe modes gives you greater visibility in low- light conditions — above or below water — and provides a bright, steady beam in either red or white light
- A dive readiness tool, developed by Garmin, shows how lifestyle factors such as sleep, exercise, stress and jet lag can affect your body’s overall preparedness for diving — offering guidance that can help you make better-informed dive plan decisions (data presented is intended to be a close estimation of metrics tracked)

### ⭐⭐⭐⭐ Review
*by J***N on 23 September 2024*

Replaced my Suunto D5 with this unit. Probably overkill for what I need and now after diving it for a year, I can see a Fenix 8 would have been just fine. I'm a commertial diver and use the t2 transmitter, but i should have got a real dive computer such as the x50i instead and bought the Fenix 8 for recreational scuba and freediving. The screen is too hard to read on the Mk3 at depth and the transmitter fails to connect at least once every dive for a few seconds up to a few mins. Its a good watch, dont get me wrong, but I could have made a smarter purchase with a little more research.
