[QUOTE="Forester, post: 207167, member: 11102"] Going from 3040 to 2960 could, I think, be a function of temperature differences, primer lots, powder lots, bullet lots...or the combination of all 3. If all of those things were exactly the same, then light may well be the issue. I bought the IR kit at the same time that I bought my CED...I have only used it twice. The first time was just to see that it worked, the second was just to prove the idea that you could Chrono in the dark (you can). Unless you know you are going to chrono in fairly dark conditions I would say save your $$ and try the chrono without the IR kit first. If you do buy the IR kit, be sure and buy the battery pack to power it as well...otherwise you need a place to plug it in near your shooting bench. The only downside I have found is that if you use the IR kit in very bright daylight you can actually have so much light on the sensors that you cause errors. One thing I would really like to do, is build a "coffin" for the chrono sensors to block out all daylight and use the IR sensors so as to take out light as a variable entirely. [/QUOTE]
