Slim Guide Skinfold Caliper AnthroFlex Kit with Body Mass Index BMI Tape Measure, Transport Bag, and Instruction Manual with Charts for Measuring Body Fat Percentage - 1.0 mm Precision (Black)

I rate the caliper; these spring loaded ones ensure a universal pressure is applied between measurements which is where i feel other styles of callipers lose repeatability. However, the tape which came with the product, has a peculiar red, amber, green scoring system. where-in if you measured over a certain waist circumference, said measurement will be in 'the red zone'. I feel this makes the product rather inappropriate for use with clients. But like i said, the Caliper is great. its the stuff i didn't care about that i don't like.
