To all, I am currently working on a device that will give a shooter the real time of flight of his bullets. This device will NOT calculate TOF rather it gives real time results. It will require a shooter to take a laptop to the range. It would also be able to be used from 0-1000 yards as well as 0-100 yards, 100-200 yards, 200-300 yards, 300-400 yards ect... for modeling purposes. This device will NOT calculate BC's ect....All it will do is give you the real TOF so that you can decide what to do with the information. You would have to also be shooting over a chrony to get an accurate velocity to go with that TOF and you would need a pocket weather station. Later in the advanced stages, there may be velocity and atmosheric data included in the software and device, but for now it is just TOF. The catch is that it is fairly expensive to manufacture. It will cost me nearly 1K to put a unit together for up to 1000 yards. A bit less for less yardage and a bit more for more yardage. Now my question to all of you is (and I am sure only a few of you would be interested in owning a unit) how many of you would be interested in renting a unit? I would have to work out the details on how to secure a deposit and legnth of time used etc..... It would be an economical, accurate and simple way to determine an accurate BC for your bullets. Oehler no longer produces the 43 which was based on a similar principal to what I am cooking up. They stated to me that the cost and time wasnt worth the amount of interest. My thought is that if someone offered a unit they can rent at a reasonable rate for a reasonable amount of time, there may be more interest. What do you think. Any opinions here are welcome.
