DZOTMYN Chronograph Shooting Arrow Velocity Meter Velocimetry Measuring Tool Chargeable Fixable

A tha panngai ltk e...good..price could be little cheaper...i guess

Always wanted a chronograph but frankly couldn't justify the cost. So, when I ran into this for about $30, I read the reviews and figured for the price worth trying it out. Unfortunately I've had it sitting since last December and finally found the time to try it out. The instructions it came with are a bit odd. It did come with an English manual but definitely written by an engineer =). Once you understand that, the manual makes sense. Also, it's actually easy to use, so that's a nice plus. I very much like the fact that the values etc reset each time it powers on, which leaves less chance to error for me. Want to add that I was pleasantly surprised how well the battery kept its charge since it arrived in December and that being about 4 months! The manual says you should cycle the battery every 3months if not in use, so I'll start doing that.I tested the chronograph on a Hatsan Jet-1. And it work flawlessly! The only thing i needed to do, since it boots up in mps (meters per second) was to push the button once so I can switch it from reading mps (meters/sec) to fps (feet/sec). And that was it! It metered perfectly & all with specs. As I said earlier, I always wanted to use a chronograph and for around $30 got one that works perfectly for my use!The only downside I could add is, if you iron sights or a top mounted laser sight etc, the way the unit sits above the barrel your sight/laser will be blocked. Again, for me, that's not an issue because I only use it to meter shots which can safely be done without having to sight in anything. Haven't tried it on anything scoped so if your scope sits high enough it might work while you sight & shoot down range. Again, I don't use it that way.All in all, ai highly reccommend this chronograph for the price! I've even seen where some folks will put a small block between the two sensors to prevent you from shooting one out, which I may do down the line. Also, I put some shrink tubing on the metal horseshoe clamp so as not to scratch the barrel. All that is 100% optional if you like tho.Works great, good battery life, wasy to use and great price for good working Chronograph! Lastly, the size of it being so small is frankly fantastic too!

Por el costo es muy buena opción para amateurs que quieren conocer un poco más el desempeño de sus juguetes. Puede dar la medida en FPS o MPS, solo que no indica de manera clara en cual lo está dando, para cambiar entre modo FPS (pies por segundo) y MPS (metros por segundo) se debe presionar el botón justo cuando acabar de encender y aparecen las letras FPS, sin embargo no muestra ninguna indicación del cambio, uno lo comprueba al hacer la medición (los fps son poco más del triple de los mps para una misma velocidad). A mi me ha servido para comprobar velocidad y potencia (con la ayuda de una bascula para medir el peso del proyectil para poder calcular la potencia) de diversos juguetes y diversos calibres y municiones, obteniendo información real y objetiva que muchas veces es diferente de lo que dicen los fabricantes o las redes sociales; no hay como comprobar uno mismo los datos. Le hace falta un Instructivo adecuado pero el costo es inigualable y al final se obtienen los mismo datos que con equipos mucho más caros.

Mi revisión esta basada en mi experiencia personal con un rifle PCPAunque la construcción es sencilla, se ve solido y el funcionamiento es bastante buenoTrae un adaptador que se ajusta fácilmente al cañón del rifle.Es fácil de cambiar de mts/s a ftp/s y en general su uso muy sencilloSi no ocupas que tu medidor se conecte a tu celular o una pc, esta es una excelente opciónMuy satisfecho con los resultados
