Hi Matt

It's a Sykes Pickevant DSS (Old model) that came bundled with the workshop equipement when we bought the business. It serves its purpose though. I expect the latest Sykes unit will do what it says on the tin also.

I find it is most useful when you find a faulty component & you want to prove that the light will go out after you spend 150 quid of your customers money.

Cheers

Dave
