I've had both the bod pod and calipers done. I've been taking classes to get certified as a personal trainer so I've had the calipers done a few times. They measured me anywhere from 26-29%. The bod pod is what gave me 23%.
You can go to just about any college that has an exercise science or kinesiology depratment to get a bod pod test. You just have to pay a fee.
I guess I just need to stop being impatient and give it time. I do have about 50 more lbs I want to drop so I'll stop worrying about it until I hit my goal. Then I'll see what happens.
