good calipers
I have been a personal trainer (10 years) and strength trainer(3 years) for a few years. I have checked thousands of body fat %. If you are looking for some very accurate calipers try the Lange skinfold caliper. The plastic calipers that many trainers use can be up to 5% off. The Lange calipers cost about $190. Just train a few clients and buy a pair. They are well worth the money
