I have just won an ebay auction for a BMI Densitometer, apparently all the seller knows is that it was made by BMI and they were in California. I thought I would have a little punt at it to see what it's like as it looks like it could be useful.

ebay Item number: 271213648188 I won it for circa $50 including the shipping so no big loss if it's no good.

Hoping someone here can help.
