Detecto 339 Mechanical Physician Beam Scale with Height Rod - Dual Reading KG/LB for Accurate Weight and Height Measurement | Perfect for Medical Offices, Clinics, and Home Health Use

This is an old-fashioned mechanical weight scale. It doesn't plug into the wall or use a battery. Nor does it have a memory to store your readings. It won't connect via Bluetooth to your computer or a mobile device. And you won't need to download an "app" to make it work. Sorry, but it's not voice activated either. Believe it or not, you make it work by using your own hands (imagine that).My unit arrived well packaged and without any sort of damage. Assembly is easy and only takes a few minutes. Using a Philips screwdriver, attach the column to the base with six (6) screws Once assembled, use a level to make sure the platform is level. If not, use a self-stick pad or some type of shim to level it as needed, (Detecto really should have designed this scale with some adjustable levelers). Once leveled, use a flat-blade screwdriver to turn a screw to calibrate zero. That's it.To weigh yourself, simply step on the scale and slide the weights until it balances. I find the readings to be very repeatable. But while being weighed you need to stand still. If you start waving your arms about or rocking from side to side it'll take forever to stabilize. I offer no scientific evidence, but I believe this scale is accurate to within about 1/4 pound.So what's the real appeal of this "antiquated" scale? I've owned several digital weight scales. After a few years they quit working and I threw them in the trash. And then I bought another one, etc. Unless you abuse it, this Detecto scale should last a long time. Spare parts are available if needed. And it looks pretty cool too. And while it costs more than a cheap digital scale, I think the price is quite reasonable for what you get; especially when you consider that it was made in the USA.
