Works great for 10m indoor air rifle
Response from developer
Thanks for your review. We are happy if you like our app. The subtitle thing is a good idea, we will address this issue as soon as possible.
Still needs work
When I tried to scan 10 individual shots, I couldn’t get it to save the shots. Also, I was using a target that was previously scanned to compare accuracy. This app was regularly .2 - .5 off.
The best way to get a good scan would be to have the large green ring line up with the shooting black. This is what I tried to do, but it was too close.
Needs more work before it’s a useable system. Will continue to use the other app until improvements are made.
Response from developer
Thank you very much for the feedback. The NRA-5 target is the same as the international ISSF 10m air rifle target, which many users have already scanned without the problems mentioned. The Blackhole app always tries to find the number of shots given by the user. This is 10 by default. In your case, please change the number of shots to 1 on the live image page and please scan each bull separately. Please make sure that the correct caliber (.177) is set and that you use a plain background with no pattern, such as a white sheet of paper. Please do not use the back of another target. You can save the result of the first bull in a new "event" after the scan by clicking on the disk icon. Since the data is stored device-independently on our server, you need an account. You can create one for free with a nickname and an email address. You can save the results of further bulls in the same "Event" preferably in the same series. You can find instructions on our website at https://www.blackhole-app.com/manual/. Also have a look at the video tutorials (unfortunately only in German), on which the 10m air rifle target is scanned. The green ring should be aligned with the outermost ring of the target. We would be very happy if you send us a picture of your target on the used background to info@blackhole-app.com, so we can have a look at the specific case and support you. We look forward to hearing from you.
