What’s the Difference?

Garmin Tactix Delta vs Fenix 6X Pro Features Compared
  1. Design

  2. Perhaps these two are some of the strongest and most sturdy smartwatches on the market as each of these is sturdily built with durable materials. Fiber-reinforced polymer for the case and silicone straps. Although, titanium, leather, or nylon straps are available for the Fenix 6X Pro. DLC material has been used for the bezels on each of these two and sapphire glass for the screen protection. These are very durable materials that make each of these two a very sturdy device. The Fenix 6X Pro also comes with Corning Gorilla Glass screen protection and stainless steel bezel which is relatively cheaper.

    Its same 51mm case size and same 14.9mm thickness. 26mm wide straps are compatible with any of these two, while its same 1.4 inches transflective MIP display that’s very easy to read outdoors.

    The Fenix 6X Pro weighs a little less than the Tactix Delta. Although, the Tactix Delta with Mil-std-810 – US military-grade rating which makes it a rugged smartwatch that ensures it can withstand harsher weather conditions.

  3. Battery Life

  4. As per battery life, each of these two has been tested to last over two weeks with smartwatch mode and over a month with the expedition mode activated. That’s some very impressive long life, some of the longest I’ve seen.

  5. Fitness Tracking

Just like other Garmin smartwatches, both the Tactix Delta and Fenix 6X Pro are fitness-oriented and fully equipped with multiple sensors and loads of activity tracking features that make these two some of the very best choices for tracking your active life especially outdoor activities.

The Tactix Delta and Fenix 6X Pro have the same activity-tracking features, except that the former features more “Tactical features” which makes it more security-focused than the later.
