Product Description: Omron HJ-112 Pedometer
No matter where you're going, make every step count with the HJ-112 Pedometer. Using Omron 2D smart sensor technology, this dual-axis pedometer tracks steps accurately, whether it's in your pocket, on your belt, or clipped to your bag.
When You Know Your Numbers, You'll Grow Your Numbers
You'd be surprised by how many steps you already take each day. A few hundred walking to the bus, a couple thousand going a few blocks down for lunch, and with an Omron Pedometer, you'll know just how many steps you're taking and begin looking for ways to see that number get bigger every day.
Every Step Counts
Omron Pedometers use smart sensor technology rather than the standard pendulum system to get a more accurate reading. Many Omron Pedometers, including the HJ-112, can be programmed to your personal stride length to provide you with an even more accurate count.
The Omron HJ-112 Pedometer Offers:
Omron Dual-Axis Technology--Counts steps accurately and quietly, whether positioned vertically or horizontally.
Automatic Reset--Start with a clean slate each day to track your steps more accurately.
Weekly Log--Store up to seven days of information in memory; resets to zero at midnight, so you're ready to go every morning.
Six Tracking Modes--Track steps, aerobic steps, time, distance, calories, and fat grams burned.
Tracking for Two Kinds of Steps--The HJ-112 tracks both regular and brisk steps separately.

A Few Steps Toward a Healthier Life
Walking is a great way to stay healthy. In fact, walking 10,000 steps a day is widely recommended by health and fitness professionals. And when you track your steps with a pedometer, like the Omron HJ-112, studies show you're likely to increase your total number of steps a day by about 2,000, or 1 mile.*
Getting Started
Warm Up First--Before your walk, stretch (arm circles, hip circles, and leg lifts) to get your blood flowing and reduce the risk of injury.
Use a Pedometer--Omron Pedometers are the partners you can count on when you want to accurately track your daily routine and help you reach your recommended 10,000 daily steps.
Set Goals--Begin slowly and work your way up. By setting goals you'll push yourself farther and achieve more.
Mix It Up--Add variety to your routine by changing pace, walking uphill, or just changing your route.
Add Resistance--Include some upper-body exercises as you walk, such as arm reaches or carrying water bottles in each hand to increase your calorie burn.

Now that I have owned this pedometer for several weeks, I can report that I am happy with it overall. It has become like an extra appendage--it goes with me everywhere, and most of the time, I barely notice it. I was dismayed by my extremely low step totals during my first few days of use, but I've already started to make progress. Although I do like the pedometer, there are definitely some features that could be better, so I have provided a detailed breakdown below.
APPEARANCE: The pedometer is a sleek little thing about the size of a flattened egg. The edges are rounded, so I find it comfortable to hold in my pants pocket, although a bit smaller would certainly be nice. The main step display is large an easy to read; there is a smaller time display as well. I have never accidentally pushed the reset button, but I have accidentally pushed the mode button.
CLIPS: As other reviewers have mentioned, the main clip is definitely bulky and could've been better designed. However, I have never had any problems with it falling off when it is clipped to my waistband, and I don't find it to be uncomfortable. I also find that the smaller, safety clip is a bit bulky and awkwardly designed, and the way it is attached to the lanyard makes it stick way out (check out the photos that users have submitted). However, a BIG plus about this pedometer is that you have the option of using it in the clip--attached anywhere on your body--OR simply tucking it in your pocket or even a handbag. As far as I know, no other models offer that kind of flexibility.
SETUP: The initial setup of the unit is very basic. Once you put in the battery (included; there is even a little "screwdriver" tool for opening the battery case), you are automatically prompted to set the time (be sure to set the AM/PM correctly) and then your weight. Next, you need to consult the manual for instructions on setting your stride length--you simply need to take 10 steps at your normal pace and measure the distance that you travelled.
FEATURES: In addition to daily steps, this pedometer also keeps track of aerobic steps (steps taken after 10 minutes of continuous walking), calories (probably not accurate), and distance in miles. Each of these statistics is kept in memory for the previous seven days, a nice little feature to have when you are trying to keep track. Another feature which I really like is that the pedometer automatically resets to zero at midnight, so you never have to remember to reset it yourself. (For those of you night owls, you can still keep stepping after midnight--your steps will just go towards the next day's totals.)
ACCURACY: I have found that when walking at a steady pace, this pedometer is extremely accurate, regardless of whether I have it clipped to my waist, in my pocket, or wherever. However, there are some situations in which the Omron HJ-112 undercounts or even fails to count steps as all. The manual notes that "The unit may not be able to count the steps correctly in the following cases: 1) When you walk at an inconsistent pace, 2) When you shuffle or wear sandals, and 3) When you fail to walk consistently in a crowded place." Furthermore, it also notes that the pedometer will not begin counting until you have been walking for FOUR seconds. So, what does this mean in actual practice? For me, it means that when I am doing things where I am moving back-and-forth with frequent starts-and-stops such as emptying the dishwasher, putting laundry away, etc., the pedometer frequently does not advance AT ALL during this time. I have come to accept this as a minor glitch; it simply motivates me to move more. Others, however, might view this as a more serious flaw.
So, for me this pedometer was a great purchase. I'm convinced that despite its glitches, its accuracy is still well above average, and I don't think you will be able to find the convenience of being able to carry it in your pocket/purse in any other brand available. Definitely recommended but with some reservations as outlined above.
Then I came across the Omron and read all product reviews as well as the one or two lab studies which compared the DigiWalker to the Omron which found the Omron to be even more accurate than the so called gold standard pedometer. So I took the plunge and bought one, despite some misgivings of my own as well as some of the negative reviews posted on Amazon. Well the unit arrived today and I tried it out after establishing my normal walking stride (I must have done this 15 times to make sure I was comfortable with the number I would enter to establish my stride). Even though I am relatively short at 5 ft 8 in, I walk rather fast (a 15 minute mile, plus or minus 30 seconds) and my stride on the tests I did was not quite 3 ft; I set the Omron for 2 ft 9 in. I take about 1,800 to 1,900 steps per mile, on level or almost level terrain.
After setting the Omron up (unlike other reviewers I had no trouble with the small screw to the battery compartment using the included tool for this purpose) I then went for a brisk walk around my neighborhood on a course that is approx 2 miles in length and is relatively level with the exception of one or two inclines but no real steep hills (note: this distance was established via automobile a few years ago, using a digital odometer, nonetheless its not an actual measured mile so the actual distance no doubt is probably off some; I plan on going to a local HS track and testing further on a defined distance measured course).
Result: The Omron counted a total of 3,869 steps and said the total distance walked was 2.07 miles. I concluded this to be pretty close and probably within 100-150 steps or so to what I probably actually took had I bothered to count each step. And the distance traveled would be in line with what I would have expected given the number of steps taken. So all in all I am very pleased with the initial outcome using the Omron.
I will try to post a followup over the next week or so after I gain more experience using it, especially if I can get to an actual measured track and count the actual number of steps taken and how that compares to the Omron. My own feeling is that if this unit can perform with 95 % accuracy it will be head and shoulders above any thing else I have ever used.
Lastly, like a lot of my purchases I got this on Amazon for about 30 to 40 percent less than competitors. And it arrived a day earlier than promised. Thanks Amazon for another job well done.
UPDATE: October 1, 2012
Purchased this back in January so I have had the Omron for almost 9 months now. Here is an update to my earlier post. Battery Life: the original battery gave out yesterday, so it lasted a pretty long time. Changing the battery took about 2 minutes but had to reset all my settings.
Accuracy: As my previous post noted this little device is very accurate in terms of step counting. In fact, I would say its 99% + accurate. I have counted my steps during short walks numerous times and the Omron is still spot on. As for measuring distance, one has to remember that each step that registers as you walk is counted adds exactly that much distance to the unit. So if you entered a 2'10" stride length, then each stride recorded on the unit is 2 ft. 10 in., no matter if you took a shorter or longer stride. From my experience ALL pedometers operate this way and there simply is no way around it. So with that said, what I have found is that on easy, flat, level terrain, where you are able to take a consistent stride, the Omron will be fairly accurate in terms of distance walked. However, if you are walking on hilly terrain, or terrain that is uneven -- like a nature trail or unpaved walkway or road -- it will throw your stride off and this will affect your distance recorded. For me personally when I am on a flat paved surface the Omron will slightly under-report my actual distance traveled but usually by only about 0.02-0.04 of a mile over a one mile measured course. Conversely, when I am walking on a local nature trail -- a somewhat uneven, unpaved surface with crushed stone -- it over-reports my actual distance traveled because that type of surface tends to throw my stride off resulting in me having to take shorter and more steps than I would on a even paved surface.
So in summary, a 3 mile walk on a good surface it will under-report your distance by less than 1/10 of a mile and on an uneven surface (and depending on how uneven)it could over-report your distance by 0.15 to 0.20 of a mile over the 3 mi distance walked. If distance accuracy is your thing, you should probably consider some sort of gps device rather than the Omron. For $20 the device is hard to beat.
Top reviews from other countries
There is a strange, perhaps 'sad', satisfaction in getting the required number of steps fitted into your day. A substantial distance travelled on foot just feels right and good. As distance is shown in miles I can relate properly to the length I have walked. The aerobic steps counter is particularly revealing - this is a count of the steps taken without pause, so on a long walk without stopping you may chalk up an impressive total. However even a busy day around the house with thousands of steps taken may show almost none of them to be aerobic.
I bought this because I gave away my last, smaller, one to my daughter in law when she was training to climb Mount Kilimanjaro.
Perhaps though more savvy people these day have apps on their phones to show the same info. Not me for as I don't carry a mobile phone.
This Omron Go Smart Pocket pedometer is less likely to be lost or washed as it has a safety lead, clip and small plastic pouch style belt clip. It is bigger than some of the sleeker, lozenge shaped ones. I find it rather clunky and noticeable.
Setting the pedometer up is OK, you have to stick a thin stick (opened up paperclip say) into the hole at the back if you get the order of setting wrong. That re sets the system.
The next stage will be for this to be a bit lighter and smaller. That said the larger display is easier to read. Flicking back through the past week can show progress, or lack of of it.
Also Omron, how about making one for dogs!
I can only comment on what I can check, that being the amount of steps taken. If those are correct then everything else must be on par, but it is the issue of the steps that bugs me. I find that if I keep the Omron in my pocket when walking, and count steps to 100, then the device invariably counts 110, or thereabouts!
But if I keep it on my belt it appears to be accurate, although whether it will be so over a long distance I could not say. Every Sunday I walk eight miles to my local town and back, and the amount of steps counted seems to be fairly consistent, but unless I count every one (almost 16,000) I cannot say for sure, hence the counts to 100 mentioned earlier. This discrepancy might be to do with the material within the pocket moving, and adding steps.
My biggest issue is with the belt/trouser clip, for I cannot keep it from riding off, except to place it on the trouser, and then tighten my belt over it to keep it in place. Even then it can come off, especially when tying bootlaces. The clip is NOWHERE near strong enough I find. I am now going to put a strong elastic band over the device, and below the belt to see if that works. A drastic redesign might be in order!
