CO Analyser for digifant tuning

Hi,

Just reading through the digifant tuning guide and it mentions setting the CO up.

I had a quick scan on ebay but they all seem to be full industrial scale machines!

Are there any inexpensive ones you can buy (ie - under 50) which will do the job accurately?

Cheers, MIke

I've got one of those that I'm looking to shift, along with a bunch of other stuff like a timing gun.
Will get an advertisement up in the next day or two.

 

Thanks - Pete - let me know if you have one to sell on, cheers
