SuperChrono updated user instructions
Posted: Mon May 13, 2013 6:26 pm
The Superchrono is an acoustic chronograph which means in theory you can just take it out of your pocket, drop it on the floor and start shooting and get super accurate results without the normal chronograph associated paraphernalia such as cables and leads, remote battery packs or screens and shades. A truly remarkable product however the instructions that come with it are a bit long winded so here is a simplified version in pdf format detailing the setup procedure and some FAQ’s and if you are a SuperChrono user new or old they are worth looking at and keeping a copy handy.
Here is an excerpt from the pdf explaining just how critical the alignment is:
How critical is aiming error?
- The key factors are distance from the chronograph to the target and bullet speed. A load with a true velocity of 1250 ft/s over the sensors, and with the chronograph aimed one yard too high at 100 yards, will give a reading of 1257 ft/s. This deviation increases with bullet speed. A bullet
travelling at 3350 ft/t with the same aiming error will result in a reading of 3451 ft/s. The deviation is 101 ft/s and
accuracy is 97%. Reduce aiming error to one foot, and deviation is reduced to 33 ft/s and precision increased to 99%. The sights on the SuperChrono are designed to be precise. With a little practice, you will soon be able to aim it to achieve close to the system accuracy of 99.5%.
We have found that if you do see a high or low reading with the SuperChrono it is going to be down to alignment and taking a couple of minutes to get everything lined up properly is going to return superb results, certainly as good as if not better than anything else in class.
