Diagnostic tools TekPro Hawkeye et al

[stufale]

Has anyone had any experience with the electronic diagnostic tools such as TekPro, Hawkeye and Blackbox SV225 on Range Rover circa 1993 and P38, in the sense of fault diagnosis, transducer assessment and relay testing in situ?

I haven't but when my Puma turns up in May I'm buying the Hawkeye as it is compatable with both the Puma and my L322. Pat
