How accurate are smart scale body fat readings?

The best consumer scales are within 2-4% of DEXA scans. They are most useful for tracking trends over time rather than absolute values. Weigh yourself at the same time daily, under the same conditions, for the most consistent data.

Can people with pacemakers use body composition scales?

No. Body composition scales send a small electrical current through your body. Most manufacturers explicitly warn against use by anyone with a pacemaker or other implanted electronic medical device. Consult your cardiologist.
