I like the features and memory capacity of the stopwatch. How ever I’m looking for one that can be use underwater.

Смятам, че хронометъра е добър за цената си. Недостатък са цъкащите копчета - невъзможно е да отмериш точно време на двама или трима, които бягат почти за еднакво време. За пръв път попадам на такъв.
Здравейте,
Благодарим Ви, че отделихте от времето си, за да ни оставите Вашата обратна връзка. Нашият екип следи всички канали, за да можем да подобряваме услугите си всеки ден. Ще предадем на нашите екипи всичко, което ни споделихте.
Спортни поздрави,
Екипът на Декатлон България!
Stopky - dobrý stisk, 300 mezičasů.
schnelle Lieferung.. Produkt wie gewünscht!
Schönes Design aber rutschiger Kunststoff. Präzise Knöpfe und riesige Funktionsvielfalt, aber die Aussage zu den 300 wieder aufrufbaren Zeiten ist missverständllich, in der Anleitung steht dann, dies gelte nur für den gerade zuvor durchgeführten Stoppvorgang, nicht für mehrere unabhängige Stoppungen. Die "Nicht"-Gruppierung der Ziffern erschwert im Alltag leider das Ablesen, genauso wie die mikroskopisch kleinen Rundenzahlen und Modustexte im unteren Bereich. Da mir die praktische Handhabung wichtiger als die vielen netten Funktionen, ging sie wieder zurück.
Die 710er ist leicht zu bedienen und verfügt über ein ausreichend großes Display, welches zusätzlich sogar beleuchtet werden kann. Die Stoppuhr lässt sich ausschalten, damit die Batterie geschont wird... Und in der Tasche oder dem Rucksack nicht zufällig Tasten gedrückt und die Uhr verstellt oder unnötig entleert wird! Absolut zufrieden! Service top!!!
En las preguntas y respuestas se contesta a un usuario que el cronómetro sí tiene la función que permite que en una fila continúe contándose el tiempo global y en otra que la nueva vuelta empiece a contar desde 0. El cronómetro permite ver los parciales una vez han finalizado pero no te permite ver en una fila los parciales corriendo desde 0 como se señala en la web. En las instrucciones tampoco pone que lo haga. Para otras cosas no parece mal producto, para lo que yo quiero que es esta característica en concreto (ver en cada momento cuánto tiempo estoy gastando en una vuelta mientras esta se está produciendo y no solo una vez finalizada) pues es como el resto de cronómetros.
No vale para oposiciones porque cuando se pone el cronómetro marcha atrás hace un pitido molesto cada minuto y se hace insoportable y desconcentrando. Una pena. Devolveré dos unidades que compré.
Beunas tardes Rafael,
en primer lugar pedirte disculpas por la mala experiencia con el produto y agradecerte que nos dejes tu opinión al respecto ya que nos ayudas enormemente a seguir mejorando sobre nuestros productos.
Siento mucho las molestias, un cordial saludo.

Bueno
Cumple c bien con las Funciones marcadas . Bastante practico aunque un poco complejo su manejo si no estás familiarizado con el.
Ok
En Decathlon todo es perfecto, siempre.
Me parece especialmente interesante en mi caso el uso del metrónomo para poder llevar una cadencia de paso en la cual estás mejorando la técnica de carrera solamente siguiendo el ritmo que te marca el crono.
Después de tener el Cronómetro Onstart 310 decidí comprarme un modelo superior. Muy recomendable para entrenadores que deben tomar el tiempo de las series. Cumplió con creces al anterior modelo y se adaptó perfectamente a mis necesidades. Tiene muchas funciones por descubrir.
Estoy satisfecho en general con la compra. Un par de detalles podrían mejrorar sustancialmente la calidad de la experiencia. Por un lado, aunmentar el tamaño de letra que indica en pantalla a que se refiere cada dato, así como las comillas que indican los segundos para ver bien resaltada la separación entre horas, minutos,segundos... Si me compro un cronometro es para tener una visión muy clara de la información que me ofrece. Por otro lado, la retroiluminación no se mantiene de forma indefinida. No sé si no he encontrado la opción, pero si no existe, creo que debería añadirse la posibilidad de mantener la pantalla iluminada todo el tiempo necesario hasta que el usuario decida que ya no la necesita o como mínimo aumentar el tiempo de apagado automático para permitir al usuario decidir cuanto tiempo desea que la pantalla aparezca iluminada.

Stopwatch with up to 300 saved lap times
Up to 99 h 59 min 59 s and 300 split times (split and lap). The stopwatch measures the following: 1/ split times = SPLIT: the time elapsed since the start, 2/ lap times = LAP: the time elapsed since the last lap time measurement.
Memory
When using the stopwatch, 300 split times and lap times are memorized. They can be recalled, whether the stopwatch is running or not. You can view the following in the memory: the fastest lap time, slowest lap time, average lap time out of the X saved times, last lap time, penultimate lap time, etc.
Coach countdown
Create your training session to manage your efforts: - your warm-up time (WARM UP) - your acceleration / fast exercises time (RUN) - your recovery / slow exercises time (REST) - the number of RUN and REST in a series (REPEAT) - the number of RUN+REST exercise series (SERIES) - your time between 2 series of exercises RUN+REST (BREAK) - your end-of-session / stretching time (COOL). Up to 99 series and 99 repetitions.
Match countdown
Countdown with several programmable times (up to 9 blocks and 99 repetitions). Perfect for refereeing a match with several periods of play.
Up and down countdown
Countdown associated with a stopwatch. At the end of the countdown, the stopwatch starts automatically. Perfect when starting a race with a countdown (e.g. at a sailing regatta).
Speed function: speed measurement
Using a known programmed distance and your recorded time, you can view your speed in km/h or miles/h The stopwatch measures LAPS (the time from your latest partial time measurement until the current moment) in SPEED mode.
Stroke function: measurement of the stroke rate
The STROKE function is used to count the number of movements per minute of an activity (strokes in rowing or swimming, strides in running). Set the number of strokes to be measured, start the stopwatch, and you can view the average frequency in Beats Per Minute (BPM) for the period.
Pacer function: stride pace
The PACER means you can set a pace per minute with beeps at set intervals. It is combined with a stopwatch. Set the required rate (between 1 and 240 beeps minute), and the stopwatch will beep at this rate to give you the pace.
Perfect visibility in all conditions
Big screen with a 3-row display. Back-lighting makes it easy to read at night.
Rainproof
This product is waterproof at 1 ATM, i.e. resistant to rain and use in a damp atmosphere such as a pool.
Specially designed for comfort and precision
The ergonomics of this stopwatch have been carefully designed so that the buttons are accessible and can be used with precision. The design of the stopwatch and its lightweight construction mean you can hold it comfortably in your hand. Because it is crucial to know precisely whether you have activated the stopwatch, you will hear a click when you press a button. The wide strap will let you keep it comfortably around your neck.
Save your battery
your stopwatch will not stay on forever at the bottom of your bag. It automatically goes to stand-by mode after 24 hours. You can also switch to stand-by mode manually.
