Sirics is a portable, easy to use body fat measuring tool that makes Hydrostatic weighing accessible and affordable. Designed by Dr. Sterling Cannon, a doctor turned mad scientist if you will! Dr. Cannon fully immersed himself in the design process for this very awesome little tool that will help fitness lovers determine their most accurate body composition, which is the ratio of body fat to lean mass. We removed the expensive equipment and captured the pure science of Hydrostatic Weighing in our Sirics testing kits so that everyone can use it – in the privacy of their own pool. Our Sirics testing kit is fully portable. It determines your body composition and fat measurements precisely, repeatedly and easily. All you need is access to a swimming pool.
