Overview

Fitbit sells this tracker under model number GA05183-GB in an Obsidian/Black colorway. Listing data here is limited to weight and color, so specific tracking features are not detailed.

Fitbit sells several tracker lines with different sensors and battery life, and this listing does not specify which features, such as heart rate, GPS, sleep stages, or app support, this particular model includes. The 3 gram weight figure in the data likely refers to a component rather than the full device with band, since a complete tracker and strap typically weighs several times that. Confirm exact features on Fitbit's own product page before purchase.

Performance notes

A fitness tracker's real-world value comes down to sensor accuracy, battery life, and app integration, none of which are captured in the data available for this listing. What is confirmed is the color and a 3 gram weight figure, which most likely describes a component rather than the assembled tracker and band.
