Buen aparato para llevar el ritmo

Seiko Metronome DM51BI purchased this model because it was recommended in a Chi running program. I purchased it in November 2018, use it an average of three times a week for thirty minutes to over two hours at a time and am still using the original battery. The biggest difference it has made for me is that I no longer have lower back pain after I run.The item is easy to set up and use (clock, beat and tempo). Your settings (volume/beat/tempo) remain the same until you change them. The item is small, sturdy and well-built. It has a clip that holds it securely to a waistband or the back of a running hat. It measures approximately 5.5 cm x 3.5 x 1 cm (deep) not including the clip.The chirping sound is very distinct and easy to hear. Using the volume dial you can adjust it to suit your needs from mute to VERY LOUD. When on a trail I turn it down to a whisper and louder when competing with traffic noise. The volume can be adjusted while running but can be a little tricky if you’re wearing gloves.You do not have a choice of the type of sound made; you are limited to chirping (and an occasional beep, see tempo below). Some have found the chirping sound annoying and that’s an individual call. I want something that I can easily hear and this works for me.The tempo function determines the number of beats per minute/steps per minute (spm) for runners at which you want to run. Using the up/down buttons will increase/decrease the number of spm. SPM can be adjusted while running.The beat function determines how the spm selected will be sounded out. You will hear a chirp for each left and each right foot strike. You can adjust the beat so that every second, third, fourth, fifth, sixth or seventh beat (foot strike) is a beep instead of a chirp. Having every third beat being a beep instead of a chirp is perfect for running (chirp, chirp, beep, chirp, chirp beep etc.). Unfortunately the beep is not as loud or distinct as the chirps and can be a little hard to hear in heavy traffic. Changing the beat selection can also be done while running.I am glad I made the purchase and have not been disappointed after months of use.

Vraiment trop petit, je ne recommande pas ce produit. Je n'ai pas suffisamment lu les caractéristiques de ce produit et notamment ses dimensions.

Perfecto

Keeps me distracted from my breathing & how hard I’m working by focussing on form & the steps to the beep. Have improved my running already.
