Thanks. In that case it is easier to stick to CED sensors. -FinnishVisitor-

Thanks. It is still possible that there is an amplifier or some other trigger circuitry inside of the sensors. Let's wait for more info. -FinnishVisitor-

Hi Everybody As I was not able to find a topic for introduction I'll do it here. I am the grown up fella from Finland. Highly interested about ballistics. I am planning to build a special set-up to measure bullet velocity retardation. A set of skyscreens connected to laptop with necessary interface circuitry. I am planning to have more than two skyscreens in my set-up in order to measure velocity retardation with higher accuracy. I have CED M2 in use and CED's skyscreen would be a good choise for my set-up. The CED skyscreens are also available as spare part as I need the skyscreens only not chrono itself. Before making an order for the sensors or skyscreens I would like to have a better understanding of the PACT skyscreens and/or the PACT/IR skyscreens. I am quite confident that here is some electronics professionals (as I am) who have PACT chrony and who have made an "autopsy" to his chrono. CED sensor/skyscreen is connected to the chrono unit by a connector with 3 wires. Obviously two power leads and one signal lead. CED sensor has a signal amplifier inside. It would be nice if somebody would answer to this question: How PACT (or PACT/IR) sensor is connected to chrono unit (how many contact in the connector).? Is there some circuitry inside of the sensor that looks like an amplifier? Or do I have to assume that PACT sensor doesn't have amplifier inside but it is in the chrono unit? thanks in advance -FinnishVisitor-
