The Tanita Ironman Segmental and Full Body Composition Monitor uses retractable handgrip electrodes, along with standard feet electrodes in order to give you an at-a-glance view of your complete body composition profile.

This device will offer the cold, hard facts about your weight, body fat percentage (total and segmental), body water percetage, muscle mass (total and segmental), bone mass, BMR, visceral fat, metabolic age and physique rating.

If you want that data - without some cute Miis to take the sting away - the product is on sale now for around the $300 mark, a little more than Ninty's balance board, but likely a little more accurate.
