I’ve been told I’m going to be shunting in the yard for a few days, the way understand it is I won’t need my tacho in whilst in the yard?? Is this correct? They do have another yard which is 50 yard up the road and I may have to go there with a trailer once or twice so would it be better to just leave the tacho in ■■ Unless it has to be in there anyway ■■ 
i take it that your in a unit? or a tug?
tug no you wouldnt
if its a unit im not sure, somebody will be along in a minute who will know better
I’ve replied to your other thread here.
Perhaps a mod could merger the two threads as it’s double post
