March 2, 2007 We’ve written about Tanita’s Innerscan previously, but the newly released Tanita BC-545 is such a leap forward in technology that it deserves more than just a mention. The BC-545 is designed to assess the impact of your training routine on different parts of your body. It is able to give individual body composition readings for five body segments (each arm, each leg and the trunk area). The measurements are taken quickly and accurately by standing on the 4 footplates and by pulling the hand electrodes that are housed in the base using retractable connecting cables. The monitor then sends a safe low signal from the hand and footplate electrodes through the body. The resistance to the measurement (known as Bio-electrical Impedance Analysis or BIA) is then fed into researched equations to provide your personalized body composition readings. As the device includes a calendar function, it can track the changes over time for you, so you can create comparison graphs showing a history for each segment of the body and for each of the body composition readings, so that you can see your progress, day by day, week by week and month by month over a three year period. The backlit buttons and animated illustrations are clear and user-friendly, and the scales come with batteries included and a three year guarantee. Needless to say, because the device sends electrical signals through the body, it is highly inadvisable to use this device if you have a heart pacemaker.
