Product Description:
Features: Stopwatch / countdown timer. Powerful 7 day / 10 week memory. Accurate measurement of speed, distance and calories. Time / date / daily alarm / dual time zone settings. Pedometer step counting function.

Product Description:
Whether you’re a hardcore adventure hiker, an avid runner, or simply looking to count your doctor’s recommended 10k steps a day, an Accelerator Series watch fits the bill. Advanced accelerometer technology provides highly accurate readings of a user’s speed, distance, and caloric expenditure via a simple wrist watch sensor, eliminating the need for funny looking foot pods or belt clips. Accelerometer technology is 95+% accurate, and much more dependable than traditional pendulum based pedometers. GPS-based running products are very expensive, complicated, and aren’t reliable for indoor training or under heavy tree cover. The Accelerator Series is the perfect combination of accurate readings, simplicity of use, and stylish design.

Speed & Distance Pedometer

  • Highly accurate step counter with adjustable sensitivity allows users to tune the sensors to their individual walking style. Doctors everywhere are now recommending 10k steps a day to maintain a healthier lifestyle.
  • All sensors are contained in a simple wrist watch. That means no funny looking mechanical belt clips our funky shoe pods.
  • Get off the beaten path! Free yourself from mileage markers at the track or trail! Pick a new route every day! The Accelerator can automatically distinguish between running and walking, and can calculate your average speed, distance, caloric expenditure, and total exercise time.
  • The Accelerator has a delayed step counter feature that differentiates between ancillary movements and actual steps. This feature provides users with the most accurate results by delaying calculation until it has registered 10 steps in a row to eliminate false step counting.
  • The smart scheduling features allows users to set the pedometer to automatically start/stop counting steps at a predetermined time every day, so you’ll never forget to turn it on.

Personal Profile

  • This feature allows users to customize their watch to their specific body type and walking/running style. No matter how fast or slow, tall or short, each user can personally enter their weight, average walking stride, and average running stride in order to ensure accurate results.
  • Hikers can easily account for loaded pack weights.
  • Runners can dial in the stride length to account for varying terrain and/or speed workouts.
  • Quickly adjust weight and stride lengths as conditioning improves.

Chronograph

  • The accelerator series’ powerful stopwatch features allow users to record exact results to within 1/100th of a second for up to 50 laps and a total time of 24 hours.
  • Although the watch has several advanced ways of calculating speed and distance, the old-school chronograph still has a place and purpose.

Countdown Timer

  • A simple countdown timer can come in real handy at times. Set it for 10 minutes as a quick reminder. Use it to monitor your running/walking pace and set speed goals. Alternative Time Zone
  • Great for those that travel! Allows users to set and display an alternative time zone along with the current home time display. Never lose track of time no matter where you are.

Daily Alarm Mode

  • We are all creatures of habit in our daily routines. The daily alarm is a great way to set a daily reminder or morning wake up alarm.

How the Technology Works
The underlying technology in the Accelerator Series Watches is an accelerometer sensor. Accelerometers are used to measure acceleration. Originally developed during the Space Race to replace outdated gyroscopes, accelerometers can be found in a diverse range of today’s products such as automobile air bags and tilt meters. In the Accelerator watch, a user’s movement (acceleration) produces varying degrees of electric current within the sensor, allowing the watch to detect different levels of acceleration, and therefore measure speed and distance.

Another way to explain how an accelerometer sensor works is to envision a marble in a bowl. When the bowl is moved, or accelerated, the marble inside will roll (accelerate) along the bottom and sides of the bowl. When the bowl is accelerated faster, the marble will move a greater distance up the sides. The accelerometer sensor in the Accelerator Series watch acts like an electronic marble in a bowl. With every step forward, the wearer of the watch (bowl) is accelerating forward. By measuring the acceleration of the “marble”, the software inside the watch can then calculate the wearer’s speed and distance.

The Competition
There are really only a few different ways to calculate the speed and distance of human-powered, on-foot travel. The first was basic math, next came the mechanical pedometer, followed by satellite tracking GPS years later. Mechanical pedometers are cheap and abundant, but also highly unreliable. They operate on a simply pendulum clicker that relies on the walker’s hip movement to count steps. Unfortunately, mechanical pedometers end up counting a lot of non-walking movements and assume that walkers are making consistent and repetitive steps.

GPS technology is impressive, but also expensive, complex, and not always ideal for outdoor activities or indoor training. Satellite signals can be lost in heavily forested areas, indoors, or behind large buildings and receiving signals eats up batteries. When a good signal can be found, often the device does not receive info often enough to account for twisty backcountry trails.

The Future
The Tech 4 O Accelerator Series fills the void between old mechanical pedometers and the overkill of GPS. A simple, yet versatile, wrist-watch design can provide extremely accurate speed and distance data in all conditions.

Overall good pedometer by sports fan

I am using this watch for a month now, i’ve done some mileage(30-40 miles) on it plus a 5 k race… The key is the initial calliberation. you need to know your AVERAGE stride length when running.for me,i have longer strides when i begin running and then shorter strides towards the end of my run. You have to run at least a 5 km (measuring it either by car or GPS) and then divide the 5 km by the number of strides you made to know your average stride length(in inches).it turned out that for me it is 49″(i’m 6′2″), although i start with a 51″ strides…(you also need to measure your walking stride length using the same method). It will not be accurate if you just calculated your stride length over a one loop on the 0.25 mile track. After knowing the 49″, it is working perfectly.It saves all my runs by day(one week history) and then accumulates the runs and saves them by week, pretty useful.It is my first pedometer by its accuracy cannot be questioned because i have a GPS as well and it is pretty precise.of course you need to keep your hand moving and not lift it still every couple of minutes…

There is a sort of glare under trees but you still can manage to see,also the buttons sometimes get pressed accidentally (just regular hand activity).

till this day,I am very satisfied with it. I also wear it to work as it isn’t bulky and looks “acceptable” with its black color and design.

Good, but bad reflection by D. Miyashiro
The watch is good, but there it has a bad reflection.

It’s hard to see the top part of the display. You can’t see

the distance display.

Is the other TECH40 watches the same. The round plastic has

a really bad reflection that makes it hard to see.

Things to know about this watch by A. J. Will
I have the runner’s watch with the oval ring. One of the things I couldn’t find when shopping was the size. The crystal is 1 inch; the case outside size is 1-5/8 inch. This watch is the best pedometer. I love how it automatically distinguishes between running and walking to measure distance, speed.

1. Two things about the domed crystal. There is always a glare which makes it difficult to read. A flat crystal doesn’t have the same glare problem. The dome is also prone to scratching, I have already scuffed mine after only 3 weeks.

2. The buttons are too easily accidentally activated. Half the time when I look to see the time, the watch is some other mode and I have to fiddle with buttons to see the time.

3. In exercise mode, time is only recorded to the nearest second, and the chronometer can not be operated at the same time as the pedometer.

4. One needs to be aware that the exercise mode starts automatically when one enters that mode (after a few seconds delay) It is easy to unintentionally add to one’s exercise record if one does not remember to stop it while looking at the data.

Overall I give the watch 5 stars as a pedometer, 4 stars on syle, and 3 stars on the watch.

tech 4o watch by Don V. Gibbons
Wsatch and pedometer are sightly complicated to use…requires some effort. Overall product is Good.
