Product Description

The BC 1706 HR with DTS is the perfect solution for all fitness-oriented cyclists. DTS stands for digital transmission system (Speed and HR), providing zero cross talk with other computers and ensuring that the data on the computer is your own. The current, maximum and average heart rate are measured as precisely as an ECG for precise training control. Both the speed and heart rate are coded and transferred to the bicycle computer by digitally coded radio waves. All bike, time and heart rate values are easily and clearly read from the 3-line display. Handlebar and stem mount. 17 Functions Wireless Speed + Heart Rate: speed, avg speed, max speed, speed comparison, trip distance, total distance bike 1, total distance bike 2, total distance bike 1 + 2, clock, ride time, low battery indicator, two bike programmable, total ride time bike 1, total ride time bike 2, total ride time bike 1+ 2, memory back up function, Heart Rate, Avg Heart Rate, maximum Heart Rate, programmable trip segment, programmable timer.

Amazon.com Product Description
The BC 1706 HR DTS with heart rate monitor is the perfect solution for all fitness-oriented cyclists. In addition to the trusted BC 1606L DTS bike and time functions the BC 1706 HR also measures heart rate. The current, maximum and average heart rate are measured as precisely as an EKG for precise training and control. Both the speed and heart rate are coded and transferred to the BC by radio waves (digital and coded). All bike, time and heart rate values are easily and clearly read from the 3-line display.

Digital Transmission explained.

The top model for heart rate measurement.

Digital Transmission System (DTS) Explained
With 2-channel radio transmission (km/h and pedal frequency) and 100% digital encoding without data loss, the DTS system guarantees 100% data security of current speed and pedal frequency values during wireless reception. It does this by calculating all relevant data, encoding it and transmitting it in data packets to the integrated receiver in the bike computer. Disturbances such as power lines or mobile phones are no longer a problem as transmission is carried out over the so-called low frequency. A double security system also ensures that only the data packets from your own transmitter are evaluated by the receiver. This means that group rides are no problem.

A further security measure is redundant data transmission so that no data can be lost. The size and quality of the receiver has also been optimized by a specially developed Sigma chip (ASIC) and integrated into the bike computer which also saves on battery life.

Customer Reviews

Terrific computer, wireless can be minor annoyance
This is my 4th bike computer over the years. The dual bike functionality is brilliant. The addition of pulse monitoring is awesome. The layout of stats is excellent -- I especially like the fact that half are triggered by one button, and half by another. That means that rather than stepping through all 20 (or so), you can access a given stat in 1/2 of the number of button presses.

The only issue is that on my trail bike with the giant, shock-forks there is a lot of metal between the wheel sensor transmitter and the receiver on the handlebars. I do lose the signal on occasion. I suspect that if I spend the time to move the receiver and transmitter around, I can improve reliability. As pointed out by others, the manual sucks. I'm not particularly pleased that all parts are held on by rubber o-rings -- not sure what UV and weather will do to those over time. The o-rings are certainly more adaptive to different diameter mounting situations, but I would much rather screw them down with clamps. Would love a temperature function, but suspect that it is not possible since device is always in direct sunlight.

Negatives aside, bottom-line is this is the best bike comp I've ever owned and would buy again/recommend to friends.

very good product
This is the best HR monitor for my bike riding I have ever had. I have owned three or four over the years of a different brand.
Thank you

Nice little device for a novice user.
This is the first bike computer I ever bought or used. The instructions are not the best. There are a lot of illustrations (pictures), but no worded instructions on the physical installation. It lacked specific details, but the pictures were pretty much self explanatory, so it wasn't too bad. Then I followed the setup instructions, which were much better (worded instructions w/pictures). I noticed the display was acting a little "whacky", and the backlight didn't work. The characters would be jumbled up when switching modes. After a while of this, I found it to be a weak battery. I changed the battery and everything worked like a charm! It has a lot of functions, and so far they all seem very accurate. Nice little device!
