Ballistic Precision Chronograph with FPS and MPS Readings, Sun Screens and Large LCD Screen for Range Shooting

THIS IS MY FIRST CHRONO AND I CLOSED MY EYES AND WENT FOR IT! After spending a whole day reading reviews and watching videos of different units I bought this one. First time users of course have to experience the world of (exceptable) lighting conditions and all that comes with the dance of maintaining the right kind and amount of light above the 2 sensors so that the unit works and is accurate. As far as reviews go, check out the reviews for the higher priced units and yes you will find the same complaints regardless of price. My strategy/approach was to buy the cheapest unit I could find that had enough good reviews to indicate that the unit could work well enough to get the job done. Many people gave this basic chronograph good reviews and like the better units some complained of getting a lemon. After playing with this chrono for just a few hours ( and doing the research) I am comfortable in knowing what to look for in a chrono I believe. Fortunately this (my first ever) unit seems to work perfectly out of the box and with all types of projectiles both fast and slow. For example i have a spring loaded BB pistol that shoots at 100 FPS and have shot hand loaded bullets at over 3700 FPS with consistence accurate readings. The phone/tablet app loaded fast and worked as described (except the app will not allow for deletion of error shots without saving then editing) This unit is basic in that it will only give a readout of the speed and do no calculations UNLESS it is paired with a android/apple phone or tablet and a external source application for various computations. This I like because my eyesight is poor and I would rather have my data displayed remotely next to me. Plus I can customize my remote display device and type. The unit is well built well and is sturdy and the readout is large enough and instant. Basically just 3 functions on one switch which are OFF- feet per second- meters per second. Other than that their are 2 ports for data connection to a external device which are a usb type port and a ear phone type plug. This unit takes a 9 volt battery and the battery compartment is big enough to hold a spare battery. This unit does have a camera mount type thread receiver on the bottom for using on a tripod or other type holding set up. I feel fortunate that I bought a unit that works as advertised,of good quality, and really cheap ($69.00) Not sure if I will ever need anything more but I can understand the value and preference of having a unit that does the string calculations WITHOUT having to utilize external devices and cables so this model may not be what some need or want, especially when you can get such features for for just a few dollars more. UPDATE JULY 14 2017 Have since purchased 2 more of these units to have on hand at different locations that I travel to and have had no issues with the units as long as I set up the lighting environment adequately. I wish the unit would reset automatically after having a read error when not using the remote app.

Worked perfectly for me. Easy to set up and the phone app is great..Those getting the "error" codes probably have it setup improperly. A few things I've learned using this unit. 1: works best on an overcast day, if the sun is blowing out the sensors, it can't read the shot. A few pieces of cardboard on the sun shades to block the sun works well. I also made "extended" sunshades by cutting up a translucent fluorescent ceiling light panel made for drop ceilings 2. the bullet needs to pass close to the center of the unit, both Vertically and Horizontally, to pickup the shot. 3: you can't place the unit too close to the muzzle, I've found that 8-10 feet away is about perfect. Follow those 3 things and it will perform very well..I was a little leery about the quality considering the low price, but I assume by requiring a phone app download to handle advanced functions and leaving out all the electronics and software to track shots and save strings gets the cost down. Everyone has a smart phone nowadays anyway, so it just makes sense to produce an affordable, good quality chronograph and let the smart phones serve as the "brains"...Tried it on an overcast day and it recorded every shot..I know from using my handloads on more expensive units that it is as accurate as the more expensive ones because it registered very close to the speeds my handloads got on a competition electronics Pro Chrono. I do suggest getting an inexpensive tripod..I ordered this one and it works perfect. AmazonBasics 50-Inch Lightweight Tripod with Bag

This is the basic Caldwell chronograph. It reads in feet per sec or meters per second. It is accurate if used properly. It can be light sensitive when the sun is very low in the sky (very early or late in the day). It comes with a sun/sky shield which provides a uniform white background that makes the optical sensors spot the projectile a little easier in less than optimal lighting/weather. This unit will not work indoors without an optional light kit (not included). Caldwell has a free app that will collect data when connect to your phone via a 1/8 audio mic style cable. You may need addition adapters if your phone doesn’t have a mic or speaker jack of this design. All new iPhones will require an adapter. With the adapter inline, the chronograph communicates with the app and you can save shot string data. The app is easier to use then my labradar chronograph app. The chronograph is easy to use. Just line it up properly and send the projectile through the sensor space between the sun shade and the body of the chrono. MAKE SURE your aim is clear of the chronograph before releasing the projectile or you may shoot and destroy the unit. It can happen easier than you think. This is my second Caldwell chronograph. The first one developed a short in the unit and cuts off unexpectedly. It also no longer communicates with the chronograph app, so I cannot capture data automatically. So if it’s broken why am I purchasing another just like the first? All these issues developed from frequent use over 4+ years of ownership. Even though this old unit has failed, I still consider the Caldwell chronograph to be a very well-designed and cost-effective tool for its intended purpose. Otherwise I would’ve not invested my money a second time. Can you buy better, yes. Can you buy better that this price point… probably not. This is my opinion, but I did back it up by purchasing the same Caldwell chronograph. If you need a chronograph, this at least is reasonably priced and well made and will likely serve you well. If you reload or are into air rifles a chrono is almost a must have.

Nach dem ersten Auspacken waren die Sonnenabdeckungen schnell montiert und das Gerät bereit zum Testen. Auch wenn sich das Plastik nicht unbedingt hochwertig anfühlt, ist der Chrony super. Bei 20 Schüssen nur eine Abweichung von 1 fps. Geschossen wurde ein Kinderrecurvebogen mit 92 fps und ein Lever-Bow mit 195 fps. Aufzeichnung mit Iphone SE war problemlos möglich. So macht das Gerät einen guten ersten Eindruck. Für den Bogenschützen nur zu empfehlen.

J'utilise cet appareil pour vérifier la vitesse de sortie des flèches quand je règle mon arc. En MPS ou FPS. Il fonctionne très bien en tir extérieur, à l'intérieur il faut un bon éclairage. Très pratique et précis.

Ottimo e indispensabile se si ricarica munizioni,soprattuto quando cambio polvere sono sempre a fattore con questo cronografo utile,semplice e funzionale.la sua app non funziona correttamente ma leggevo che dipenda dallo smartphone Per i commenti negativi non teneteli conto,nella descrizione c'e' scritto per uso esterno altrimenti necessita del kit infrarosso,si pretende troppo a poco!Ottimo e consigliato dopo 1 anno di utilizzo si conferma indispensabile

Funciona como descrito. Bastante preciso. O cabo para celular junto com o software da Caldwell torna automático o registro dos disparos e já dá a média.

The chronograph looked brand new contrary to another review and functioned perfectly. I love the smartphone connection with the cable where you can view from a distance and save the groups. A bit of trial and error to work out the operation of the app. I tested it on a cloudy day without the screens. I replaced a very old Chrony Delta which I shot up accidentally. It was a blessing in disguise. For the price, it was the best around and the Amazon delivery was super fast.
