Thanks, I have not looked at the Metrel's but I shall now.
They do not appear to be so widely disussed but I take it that you are very happy with yours?
Been using it for about 7 years I bought this model as it does earth resistance tests on rods as some of the work I did was on earthing comms masts and installing lightning conductors. Has been a very good meter and would certainly replace it with another if the need arose
