calipers, for like 8 bucks
I got a scale for like five bucks and it tells me my weight. The rest I can eyeball and get close.
Those scales work by passing a mild electric current through your body and measuring your conductivity, then estimating your bf% based on a pre-determined formula (which will be less accurate for some people than for others). You can vary the results by taking a shower, breaking a sweat, or even flexing hard (try it).
In absolute terms, I’d take any reading with a few percentage points’ grain of salt. If you take the measurement at the same time each day, however, and under the same conditions, the scale could give you a decent idea of relative changes in your bf. So could a mirror. The hydration function is intriguing, potentially useful – but you can get that from glancing at your piss.
I actually have a scale like yours (though mine was only $30). The weight really is the most useful (and accurate) part, though.
