They are banned, they are outlawed Sunray, there`s even been amnesties for you to hand them in at the police station
(yes OK I`m only joking mate)
but although they were popular in the 60s and 70s around here they are very old hat these days and not very reliable,
Perhaps if you were to bother to learn what they are capable of you may change your mind.
my mate got a shock off his, dropped it in water by accident one day, shook it dry, put it in his toolbox for a couple of days then got it out to "test" something OUCH! daft git. LOL. They can give false negatives too.

OK for party tricks but I would not really expect a pro to use one,

except as a handy driver for say alarm system control panels where they can be a convenient fit (off course you remove that neon and resistor first).
Why destroy a perfeclty standard bit of test kit and yes things have moved on a bit, there are now LED versions available which do more than the neon versions.
I think we have moved on a bit since the days it was popular mate
One supplier I used (very pertinant to the controls industry) reckoned to sell around 2000 of them per annum which worked out to about 2.5 per account holder.
PS - head of Electrical Engineering at my local college used to say to his classes on the subject of Mains Tester Neon Screwdrivers - "Who in their right mind would deliberately make themselves part of an electrical circuit?" I think he was right.
As John has pointed out we happily use our body in a circuit in a daily basic with a touch screen and of course we nearly all use a mobile phone on a daily basis and happily become part of the aerial system with radio frequency voltage/current flowing through our body (Let's not forget such a system contained in a Faraday cage is also used in the kitchen to heat food and that signal is only 40dB stronger) but like every other piece of test kit one has to learn how to use them, their safety and their limitations.
I'm happy to admit that faultfinding in a control panel my first port of call is a LED screwdriver and in many instances of such it is the only bit of test kit I require to get the system working, I'd love to know of anything easier.

There is nothing wrong with screwdriver testers, Professionals should have no difficulty learning how to use them, their safety and their limitations but sadly I know many who have failed to understand and disregard them, simply because they are not in the curriculum but give them a bit of high tech kit like a phone or MFT and they soon sort that. Let's be honest here; far too many electricians seem to fail miserably to understand how to fault find if the number of 'repeat visits' I'm asked to sort out is anything to go by.
There are lots of other things that have also gone out of fashion, such electric drills in favour of battery versions costing 4 times the price, but I'd happily collect £1 for every time another person on site has borrowed mine as their battery has gone flat or it's simply not man enough to do the job, I have no doubt that would
easily pay for another drill or three. Or a hand cranked meggar which has been, and still is, perfectly adequate for the job. Let's be honest here, the screwdriver is also dropping out of fashion, one chippy we seemed to regularly meet never brings any to work in favour of a cordless drill but then regularly borrows to complete his work.
Would I work in an IT environment without a screwdriver (or some other non contact) tester? NFW... They have saved me from a belt far too many times.
