They hook you with a cheap model knowing that you will want more…Hmm, just like the airguns you are shooting. We ask ourselves, do I really need a chronograph? Yes, we do need a chronograph…and it needs to perform well. The SC F-1 is seductive because it is the least expensive. However, once you have been drawn to the dark side…AF guns, PCP guns, well the accronym BOAT applies Break Out Another Thousand. Look! Up in the sky! It’s, it’s super pellet!!!! (Sorry, I couldn’t resist.) ? WOK makes a good point though, without a chronograph, you can imagine your pellets going faster than a speeding train, able to leap tall buildings in a single bound. That’s also when I took a good look at the ProChrono and observed the placement of the sensors. I thought that it was just me who was getting so many error messages until this became a popular topic.
Ii was able to figure out what was going on with my airguns with the sc product even though there were many error messages. I bought the sc because that’s what pyramid stocked and I didn’t know any bettter. I am actually pleased that happened as I am much more pleased with the ProChrono and its usere interface. That individual I dealt with went so far as to say that I was trying to steal from them. Regarding the sc company itself, there are reports of people who have been treated well, and those like me who were not. The better user interface is a result of better engineering…perhaps by someone who actually is a shooter. Debris such as dust and paper fragments will decrease the chronograph’s performance. I placed a large piece of clear packing tape over the sensor openings of my ProChrono to keep dust and debris off of the sensors. I think that the better performance of the ProChrono is due to this design difference. I noticed that the sensors are recessed deeper into the ProChrono than they are in the chrony.
