You mean the T5 models , I have one but never tried it , does that have a 1 pole function ?I have a Martindale single pole one, and it does tend to stay in the tool bag. I do sometimes use it when confronted with an unlabelled heating connection box, I can often leave it balanced / propped in the choc block under it's own weight and hear the beeping when I activate the programmer etc. I think that's the only time it sees the light of day. Otherwise I've gotten used to the Fluke two pole and find it does all I need including a one pole function.
I was looking at the single-point contact testers but nicebutdim said he didn't use them much either .I figured in the end non-contact will usually be more convenient
