Oregon Scientific SE300
Heart Rate Monitor

The main features of the Oregon Scientific SE300 are:

• Continuous heart rate monitoring
• You can manually set your heart rate training zone.
• You can also get the watch to set your heart rate training zone automatically for you, based on your gender, age, height, weight, activity level (how often and heavily do your exercise) and target activity (how intense do you want your training to be).
• You get your Body Mass Index computed after you have entered your personal data.
• An audio alarm (if switched on), wrist watch vibration (if switched on) and visual indicators alert you when you are training above or below your heart rate zone limits.
• You can have your speed and distance measured while you are running. This feature does not require the use of a foot pod.
• Timer and stop watch. You can do three types of training: Timer-based Smart Training Program, the usual stop watch based training and speed (or time) target-based training.
• During your speed training, you can set upper and lower speed limits with audible and visual alerts if you run too fast or too slow.
• You can also set a succession of targets (up to 9 and based on either distance or time) with your speed training. When you reach each target the watch beeps and you move on to the next target.
• When you are doing the speed training with targets, you can review the following data in real time: target distance (or target time) remaining, speed, heart rate, current time, current pace, total distance covered so far, average speed, total time spent training so far, average pace.
• When you are finished with the speed training, you can review: Time elapsed, distance travelled, average speed/pace, average heart rate both for your overall training and for each individual target.
• You can mark laps using the stop watch. You can take up to 60 laps in total.
• Auto lap: A lap can be automatically taken after you have run a pre-set distance.
• You can set up 3 exercise profiles. Each exercise profile sets up what intensity you want to train at. Effectively it defines your heart rate training zone. You then choose one of the profiles for use with either the Smart Training Program or the stop watch.
• The Smart Training Program consists of a warm up period, an exercise period and a recovery period with your heart rate limits being set automatically for you. The exercise period can now be repeated up to 9 times. The end of each period is marked by the firing of a timer. The periods are adjustable in length, except the recovery period (fixed at 3 minutes).
• While the Smart Training Program is running, you can review the following data (in addition to the current heart rate): Remaining warm up or exercise or recovery time (depending on what stage of the program you are in), calories burnt and % of fat burnt, current time, distance covered and speed/pace
• While the stop watch is running, you can review the following data (in addition to the current heart rate): Current stop watch time/split time, lap time, calories burnt and % of fat burnt, current time, distance covered and speed/pace.
• When you have finished your Smart Training Program or your stop watch based training, you can review: Total exercise time, maximum heart rate, recovery heart rate (only when you do Smart Training), average heart rate, calories burnt, % of fat burnt, time in/above/below target zone, distance, average pace/speed, and maximum speed
• If you have taken laps during your stop watch based training, you can review for each lap: Lap time, lap number, maximum heart rate, split time, average heart rate, calories burnt, % of fat burnt, time in/above/below target zone, distance, average pace/speed, and maximum speed. All of the information is related only to the particular lap you are looking at. It is very detailed.
• Basic time keeping: Time, date and one alarm. You can set it to go off every day, only on weekdays, or only on weekends.
• Backlight
• Wireless heart rate monitor (ECG accurate) with a digital only chest strap transmitter and a wrist watch receiver.
• Keypad lock on wrist watch so that its operations are not affected by the accidental pushing of buttons
• Keypad tone: If switched on, you get a beep pushing a button. If switched off, you get silent operation.
• Battery for chest strap transmitter is user-replaceable.
• Mounting bracket

The features in bold above denote the features that are different between SE232 and SE300.

The Oregon Scientific SE300 heart rate monitor introduces speed and distance measurement for walking or running, using acceleration sensor technology. You will have to do a calibration before using it for the first time. It will measure your speed and distance while you are running, without requiring a foot pod.

You can now also do speed training and run according to (or more like within) your preset upper and lower speed limits. This is useful if you want to take a break from heart rate based training.

When you use the stop watch and take laps, you can now get the Oregon Scientific SE300 to take laps automatically for you. Because it now has a distance measurement capability, it now knows when to do this for you (within certain accuracy limits).

Most of the other additional features relate to the reporting of speed and measurement data. If you like numbers, you are going to have a field day.

Note that because the Oregon Scientific SE300 uses purely digital transmission, it can no longer be expected to interface with gym equipment.

Summary

Just looking at the huge list above, you can see that the Oregon Scientific SE300 offers a lot for runners. All in all, the Oregon Scientific SE300 is a full featured heart rate monitor.
