Plastic ones are the cheapest. A proper Metal Caliper the dietitians use cost roughly R10 000.

Dischem, around R300/500 depending on the caliper.. Not sure if they still stock them.

I have one of these:

I bought it here for R160 and received it two days later:

I see no reason why a plastic one will be less accurate. The accuracy will depend on the user doing the measurements and not the equipment.

Ahh, they use javascript and not php, so I'm able to view the source.

See I have to ask permission to use it though, so if the guy says it's fine I will implement a similar calculator here:

Code:

function calc (form) {

Email sent, but if he doesn't agree I will just find the formulas somewhere else and write my own algorithm.

Do you just enter your measurements into that calculator?

If working on body and character doesnt cost you something its woth noting. If criticism is all that proceed out of your mouth then know that is how you feel about yourself and depicts the health of your soul.

Just been to a biokineticist to have my bodyfat% measured. He did an 8 point skin fold test. Measured me at 10.2% Now I know that this is impossible. Used the above calculator and got a more realistic +/- 13.5%. Most of my folds were around 10 and 12mm but my abdominal area and Iliac crest (hips/love handles) seem to be a problem area. they're 17mm.

Is 13.5% acceptable to start a cycle?

i bought these ones,and well after the second reading they broke,the round part of the plastic just snapped.so to the bin they went... off to bodybuilding.com to see what i may find
