They're pretty easy to clear out. Just open up the unit a crack and shake all that crud out. The BB's get in there from shots that aren't straight through the tunnel. They end up clipping the optical ports at the end, which leaves shards (and sometimes full BB's) inside the unit.
This will happen with any type of tunnel chrony like this. The only way to avoid this is to get an open system, such as the Shooting Chrony, or CED units. They're much pricier, but if you want a truly accurate chronograph, these are the units to use. They're also great for recording things that you could never fit through a tunnel chronograph... such as grenades, real firearms.... baseballs? LOL.
Again, they're not cheap. To get a fully spec'ed out unit that's compatible with indoor lighting, in a full shooting station that can record data to a computer, you're looking at about $350.
Same goes for getting the TOUT message. It's caused by not shooting straight through. You might be straight on the left-right, but because it's difficult to see your alignment from the side (unless you have a mirror beside your shooting station), it's very possible you're positioned high and shooting at a downward angle.... or you're positioned low and shooting upwards.
End of the day, get what works for you and your needs. For the occasional output check, the cheaper units work fine. But for heavier work, the more expensive units are worth their weight in gold.
