Yes, that's the stick.
There are also flags, that can hook together
There's a one flag, a two flag, and a three flag
All four itmes listed here:
http://buy1.snapon.com/catalog/tools.asp?tool=all&SUB_Cat_ID=3058619&SUB_Cat_NAM...The 2 flag is a new item, that we can see no use for at all.
The flag sets daisy chain together, like christmas tree lights, so with 2 3-flags and 2 1-flags you can do almost anything (except of course 10 cylinder engines.) that combination gets you 3, 4, 5, 6, and 8 cylinders.
The flags are more versatile, but more of a pain in the butt, since they don't really clip to anything. we use masking tape to hold the stuff in place at times. the stick you just hold over the top of the coil packs, all 3 or 4 (of course depending on your application, we do use it on 1 bank of a V6)) and you've got your pattern.
The stick comes in very handy on the cars that use three coils on the plugs on one bank, and three wires running to the other bank.
To make a strong point, these do NOT work on all cars. We also have the Pico secondary COP probe, and have compared the 2 systems. Some vehicles, like the above mentioned GM 4.2 simply must be too well shielded for either set to work. But we have had very good luck with the Chrysler applications, and VW. For us when one system does not work, the other one does not either.
Either system does not, like almost all secondary pickups, give accurate voltage readings. But they both do what they are supposed to do, so you in a very short period of time you know whether or not you have a secondary problem, and which cylinder.
To use these snap on systems you need an adapter. You need female rca to bnc. We use the same adapters we use for the chassis ears. Then you can use the bnc to bannana adpters that comes with the pico set, and that Tom sells. Or you could use dedicated bnc to bnc cables, and the bnc to rca adapter.
Any further questions feel fre to ask and we will do our best to answer
