Reviews Of The Garmin Instinct 3

Use context
Regular user of connected watches for hiking, trail and indoor fitness. Choice motivated by the legendary robustness of the Instinct range, the AMOLED screen and solar autonomy. Intensive test over 3 weeks with daily port (activities + health monitoring 24 hours a day).

First contact and installation
Surprising housing by its lightness (10g less than the 2x instinct), discreet metal reinforcement. AMOLED screen immediately attractive with vibrant colors.

Issue : Initial firmware buggy (2 dials only, absence of the Sleep Coach) resolved by update via Garmin Connect
Handling : 15 minutes to configure essential widgets. Architecture 5 intuitive buttons for Garmin regulars.

Real test vs promises
What is holding ::

Real 8 -day autonomy (AOD activated + 3 hours GPS/week)
Practical torch in night hiking (improved VS 2x menu)
Reliable nap detection (precision at ± 10 min)
What is fishing ::
Elevate 4 cardiac sensor (2019): Erratic climbing and swimming measures
No cartography : Navigation limited to the “BREADCRUM” layout
Interface Training Weight: Forced return to the list after each series

Key points for the buyer

For : occasional hikers / fans of robust / allergic design at TouchScreen
Avoid : Need detailed cards / requirement on cardiac follow -up / tight budget (€ 500)
Alternative ::

Cash verdict
▲ 3 assets ::

Incredible autonomy (solid 2nd in shipping)
Readable screen in the sun (adaptive backlight)
Minimalist interface + physical buttons (wet gloves/hands)

▼ 3 weaknesses ::

Obsolete cardiac sensor (underestimates the efforts of effort)
Rudimentary navigation vs fenix/epix
High price for 2021 specs

Recommended ? Yes, for outdoor athletes prioritizing sustainability on peak metrics. Not recommended for demanding trailers (lack of topo cards) and gym rats (interface bugs). A transition watch between the entry -level and the Fenix, to be bought on a promo under € 400.

Case where instinct 3 is not suitable

1. Need detailed cartography

Navigation is limited to the “Ariane wire” layout (empty screen line) without offline cards. A major weakness for:

Mountain hikers/complex environments
Demanding trailers (no route recalculate or topography)
Travelers in total autonomy (dependence on the smartphone via Garmin Explore)

Alternative : COROS PACE PRO (Color Cards) / used Fenix 8.

2. Cardiac precision requirement

The sensor Elevate Gen 4 (2019) Shows gaps:

Underestimates short effort peaks (eg split)
Erratic data in climbing, swimming and cold time
Delay of 5-15 sec on brutal variations

Public concerned ::

HIIT athletes/polarized training
Swimmers (“indicative but incorrect” measures)
People watching a heart pathology

Solution : Opt for the coming 3 (Gen 5 sensor) or Forerunner 265.

3. Tight budget with premium requirements

At € 500, the 3 amoled instinct suffers from the comparison:

SUUNTO RACE : cards included at 450 €
Fenix 7 Pro Reconditioned: Gen 5 + music sensor at € 550
Come 3 : touch screen + Gym follow -up optimized at € 450

Criminal detail : the slow CPU (inherited from the 2x instinct) prevents the addition of Endurance score or route recalculate.

4. Intensive gym/crossfit (See watches for crossfit, here)

Persistent interface bugs:

Forced return to the list of exercises after each series
No personalization of rest screens
Absence of “free” mode for weightlifting

Reddit user reaction :: “I resumed my 2x for my workouts, too much frustration”.

Verdict ::
Instinct 3 fails as high-end all-terrain watch (lack of cards) and as pure performance tool (aging sensor). His niche: outdoor athletes occasional Favoring autonomy (+28 days solar) and resistance (MIL-STD-810 standard) on advanced metrics. An expensive transition between entry -level and fenix.
