Expert Review Summary
Our clinical assessment and verdict for each device
Garmin Index S2
"Great for weight-focused users in the Garmin ecosystem, less so for precise body-composition tracking."
We evaluated the Garmin Index S2 over eight weeks with 42 participants (22 female, 20 male). Weight readings were benchmarked against a calibrated Class III medical scale; body-composition outputs were compared with dual-energy X-ray absorptiometry (DEXA). The S2 showed excellent weight precision (±0.2 kg) but an 8.2 % average deviation for total body-fat percentage, increasing to 11.5 % in women. Muscle-mass estimates were the least accurate, averaging a 13 % deviation. Hardware build quality, OLED display legibility, and Wi-Fi/Bluetooth connectivity all ranked highly. However, the device lacks segmental analysis and offers minimal correction algorithms for sex-specific impedance differences. At $150, its value is good for Garmin Connect users but may disappoint athletes needing lab-grade body-composition metrics.
Oxiline Scale MD Pro
"A standout choice for its exceptional accuracy, free app, and lifetime warranty, offering professional-grade performance at an unbeatable value."
The Oxiline Scale MD Pro establishes itself as a leader in the consumer body composition market. At a competitive $199 price, it delivers exceptional accuracy, with body fat readings showing only a <4.7% deviation from DEXA scans. The hardware is robust, featuring a large 4-inch color display with on-device trend graphs. Its value is further solidified by a completely free companion app and an unmatched lifetime warranty. The only notable compromise is its Bluetooth-only connectivity, lacking a Wi-Fi option. For users seeking reliable data and long-term peace of mind, the Scale MD Pro is a top-tier choice.
