The Omron thing is close to the calipers, by probably 1%? Take it for whatever it's worth, I did calipers 2 days ago & 1 reading on ab gave me 12% read & Omron today gave me 12.5% read, ????? But like everyone said Dexa, Scan , but I can't find one yet??? Keep up the good work !!!! Going to do caliper early in the AM to see???
