I am a 58 year old spark who has been off sick for a while .I have been offered some work testing some flats but I need to update my test equipment. I have the old Robin test kit in the case but the calibration certificate is out of date. I was thinking about a multi-function model but I have read bad reports on many brands I am not sure which one to get. so I thought I would seek the advice from the people who use these on a daily basis to seek your opinion. I hope you can help thanks
