The ePulse works by integrating light sensor and microchip technology--the same type used in hospital heart rate monitors--to accurately read the pulse from the forearm. Once on your arm, the ePulse continuously acquires and shows your current exercise heart rate while calculating calories burned based on your heart rate and personal profile. If you use the ePulse several times a day, it automatically compiles your calories burned into a grand daily total, including when your activities consist of moving around the office or doing work around the house. The ePulse also measures your basic metabolic rate (BMR), which is a prediction of how many calories you will burn based on your personal data input, and then adds your daily calories burned to show your total caloric burn for a day. This function is particularly useful for people who are trying to count calories and lose weight through a program of diet and exercise.
In addition, the ePulse handles a number of basic calculations, including elapsed exercise time, average heart rate, and minimum and maximum heart rates. People with specific training goals can further use the ePulse to calculate optimal heart rate exercise zones for both burning fat and boosting cardio conditioning. The ePulse will then provide a target high and low range for your heart rate, with a green LED light telling you when you're in the target zone.
The real advantage of the ePulse, however, is its chest-strap-free design. At best, chest straps are an annoyance, and at worst are so uncomfortable that they alienate many people from using this type of valuable training and fitness tool. Women in particular report sensitivity to chest straps, and many won't use heart rate monitors as a result. The ePulse, by contrast, is comfortable for both men and women, allowing users to easily regulate their workout intensity and better attain specific fitness or weight management goals. The ePulse--which incorporates an easy-to-ready day/night LED display and is powered by AAA batteries--requires no programming to immediately display heart rate data.
The ePulse excels during the following activities: general fitness, aerobics, running, tennis, racquetball, golf, resistance training, weight loss monitoring, weightlifting, and daily chores.

E-Pulse - a promising device but not there yet!,
By
Amazon Verified Purchase(What's this?)
This review is from: Impact Sports ePulse Strapless Heart Rate Monitor Watch and Calorimeter (Sports)
After reading the mostly positive reviews of the ePulse on Amazon, I decided to purchase the device about one month ago. I work out quite hard and pushed this device to its limits. Here are my general thoughts on the ePulse.
If all you are looking for is a device that gives you a real-time measurement of your heart rate, this device works fine. However, other functionality does not deliver as promised. The minimum heart rate is set to 0. The watch seems to take awhile to average out that 0 heart rate when calculating average heart rate for the entire workout. If you are working out for several hours, this shouldn't be a problem, but the average heart rate will report several beats too low if you are doing a shorter workout (such as 30 minutes). Also, if you attempt to view other data screens such as maximum heart rate while working out and then go back to current heart rate, it will read way too low. It takes approximately 30 seconds to re-adjust back to your actual heart rate. At high heart rates (such as 160-170 beats per minute (bpm)), the watch will occasionally stop adding calories burned to the device. For example, during a tempo run where my heart rate was near 170 bpm for ten minutes, it told me that I burned a total of 15 calories over the ten-minute period. When I went back to a lower heart rate in the 145-150 bpm range, the watch started calculating calories burned much more accurately. I have spoken with the designers of the ePulse, and they told me that they were able to replicate these problems. They intend to fix them for their new model release. So, if you are looking for a device to simply give you a measurement of your current heart rate and don't care about any other bells and whistles, this device is fine. However, if you want to know an accurate idea of how many calories you burn and what your average heart rate is, I would wait the 6-12 months for the next release.

New State of the Art,

This review is from: Impact Sports ePulse Strapless Heart Rate Monitor Watch and Calorimeter (Sports)
I put my new ePulse monitor through some tough paces this weekend. I started on Friday with an intense 40-minute workout with my personal trainer, mainly lower body and aerobics, and found the device to be very accurate and reliable. Over the weekend I played two rounds of golf in the heat using my cart but with a lot of walking and climbing around the rocks and roughs, places where one is not supposed to venture during golf. I wore the unit the whole time, both days, and had inputted my personal information to the device. Here are my observations:
1. Golf day one: 4 hr 55 min, temperature range 92-104 F, total caloric burn 833 cal, range of pulse rate was between 59 and 105 Golf day two: 5 hr 1 min, temperature range 90-99 F, total caloric burn of 842 cal, range of pulse rate was between 56 and 102 (Note: I kept the unit on continuous monitor so I could watch the data) 2. The armband is non-intrusive. Once it's on a few minutes you don't even think about it, while on first inspection it looks "bulky" it's actually light and unobtrusive. I actually put it on pretty light and only once did is slip during a wild drive swing. 3. It was hot and I got pretty sweaty. No problems were encountered with the sweat or the armband staying put. Except when I looked at the readout it was out of sight and out of mine. 4. The unit was really easy to read except in bright, direct sunlight. In direct sun and wearing sunglasses one needs to shield the screen with ones hand. Still, it was very readable. 5. I never once noticed a missed beat or had to reset or maneuver the unit to get continuous readings. Seems very stable and accurate. In my case anyway, precise location of the sensor was not required. 6. Battery consumption was about 50% with new energizer batteries each day (again using continuous monitoring not the on-daman feature). Although, it was still running well even after the screen told me to replace the batteries. My conclusions are that the ePulse has set a new state of the art in fitness monitoring, is an excellent exercise and health tool and is totally usable for anyone wanting pulse rate and caloric burn info. The other functions likewise will be very valuable to many users. Battery life is a bit short but when the unit is used in the "on-demand" mode this becomes a non-issue. The direct sun impact on the readout is not a huge problem when compared to the ease of use and performance. All of this good stuff and NO CHEST STRAP required! A VERY HAPPY ePulse user.

Decent tool if you use it right,
By oldtaku (San Diego, CA United States) - See all my reviews

This review is from: Impact Sports ePulse Strapless Heart Rate Monitor Watch and Calorimeter (Sports)
In spite some of the warnings in the reviews here I bought this because I dislike strapping stuff to my oh so manly chest when I'm sweating gloriously while exercising and the hand pulse sensor on my stationary bike is cruddy.
Good stuff: - It's very accurate. I've got my 40-hour Red Cross First Aid cert, so I know how to take a pulse, and this thing is within a beat or two over a minute, which is well within the margin of error for it, my timing, and its averaging (see below). - Since you enter all your personal data like weight, age, and height (if you can figure out how - read the little manual once) I trust the numbers this puts out more than other devices that claim to measure calories (like my bike). - Once you strap it to your upper forearm it's pretty unobtrusive and light. - Doesn't require you replace your beloved wrist watch like most other solutions. - It's water resistant, so easy to wash (just don't throw it in the washing machine). - The bright red LEDs are a cinch to read in any condition. - You can indicate whether you want to keep your heart rate in the fat burning zone or the cardio zone, and a little led will indicate when you're in the zone. - Acquires the heart rate pretty fast compared to other devices I've used, and a blue LED indicates when it's locked. - Comes with a little sticky velcro pad you can use to attach an mp3 player to. Very nice. Bad stuff: - Requires 2 AAA batteries and doesn't come with any. Good thing I'm a nerd so always have spare NiCads. - The buttons are water resistant, which makes them rather hard to push. See below for my suggestions. - Who designed this UI? I could certainly do better with 3 buttons. But once you get it set up you can just use the left one for the most part. - Could really use an audio indicator for when you're out of your preferred zone so you don't even have to look at it. - Assumes you're using this long term every day, which I suspect is not the model most of us are in. Not many people are Ironman Triathletes. So the running average can take a little while to catch up. Luckily there's an easy way to reset it. So here's my take on how to use it: - The first time you turn it on READ THE LITTLE BOOK and set up your personal info, then just use the left button after that. Make sure you set whether you prefer fat burning or cardio mode. - The buttons are hard to press normally, so slip your index finger under the band to act as a firm surface (the battery pack makes it easy) and use your thumb on the same hand to push the buttons - now it's easy! - Hold the left button for 3 seconds whenever you start your exercise to reset all the daily stats so there's no issue with long term averaging. - Give it 10-20 seconds to find your pulse (blue LED on the left lights up) and then average it out. That seems like forever when you're watching it, but is very reasonable for a device like this. - Watch the LED on the far right. If it's on you're in your fat burning or cardio zone for your age. - Press the left button once to see your workout time and twice to see your calories burned, then once more and you're back to pulse. With that I find it's a great little device. Seeing your heart rate really does provide great biofeedback.
