Until recently most pedometers counted steps the same way. Times change and so does tech. On the outside pedometers may look alike, but it’s what’s INSIDE that counts. At Pedometer Express, we know pedometers inside and out.
PENDULUM PEDOMETER FACTS
Invented almost 400 years ago, a pendulum is definitely an “old school” mechanical device for estimating movement. As an example, an antique grandfather clock uses a pendulum which swings back and forth to count seconds. A pendulum pedometer uses a miniature version of the same tech to count steps. With no computer chip inside, pendulum pedometers are less expensive than motion sensor models.
WHY IT MATTERS:
Because of the way they count, pendulum pedometers must be worn on the hip to count correctly. They must also be worn relatively level to the ground, and not tilted too far forward or backward. Care must also be taken to maintain the pedometer in this position for continuous counting accuracy.
Pendulums are sensitive mechanical devices made with parts that move, including levers, springs and wires. While no one plans on dropping a pedometer, it does happen, especially with certain groups of walkers. Dropping the pedometer or other rough treatment, intentional or not, may dislodge or ‘hang up’ the pendulum. This will result in inaccurate step counts or a broken pedometer.
MOTION SENSOR PEDOMETER FACTS
Thanks to the computer age, the motion sensor chip was invented. Motion sensors go by many names, such as accelerometers, tri-axis, and 3D sensors. In the past decade, highly accurate motion sensor computer chips have become commonplace in pedometers and trackers, making them much more affordable.
WHY IT MATTERS:
Motion sensor pedometers ditch the pendulum and have no moving parts. Motion sensor pedometers are very durable, much better at withstanding rough handling, last longer, and can be re-used for multiple groups or programs. This makes them more economical in the long run.
Unlike pendulum pedometers, motion sensor pedometers can be used in almost any position on most any part of the body, so there are fewer issues with walkers not wearing their pedometer correctly, compared to a pendulum model. They may be carried in a pocket, or worn around the neck on a lanyard. Some even come with a clip so walkers can even wear them “old school” style!
Motion sensor pedometers tend to be more accurate for a wider range of walking styles. This includes slower walkers and those with less hip flexibility. This can be important for some adults and seniors.
SO A MOTION SENSOR PEDOMETER IS BETTER, RIGHT?
Yes, but pendulum pedometers still have their place. Pendulum pedometers are definitely cheaper. Today, they are called “promotional” pedometers. They are used as handouts at health fairs or events, to promote and encourage walking.
If budgets are restricted, pendulum pedometers are still a good tool to encourage walking, and studies show people who use pedometers walk more than those who don’t, by about 20%. That’s substantial, no matter which pedometer you use to encourage walking.
Overall, motion sensor pedometers win when it comes to accuracy, durability, and flexibility. There is one other benefit of a motion sensor pedometer, a benefit that goes beyond cost.
PROGRAM ADMINISTRATORS EXPLAIN IT BEST.
We often hear from program admistrators who have past experience with pendulum-based pedometers in their programs. The number one complaint is poor quality pendulum pedometers from other suppliers.
And when participants have issues, the program administrator is often the point of contact, which means dealing with questions and problems from unhappy participants. They tell us it’s time consuming and can be frustrating. Many groups who went the “cheap” route the first time, tell us the dollar deals aren’t worth it. The old saying “you get what you pay for” is certainly true when it comes to the type of pedometer you choose for your program.
We know you’re on a budget. At Pedometer Express we want to help you get the best value for your dollar.
