How important is surge protection for Digital DJs?
My friend is using a Surge Protector when using his equipment on clubs.
Do you guys use it? Is it an overkill or maybe even more protection like a no-break would be better?
Thanks.
Better to be safe than sorry mate 
A protector might help if you have poor quality electricity supply, but it won’t give any protection from a lightning strike for example.
You’re definitely going to want protection from this guy.
Thanks, but then there is nothing that us DJs can do right? Or is there?
out at a gig you should ALWAYS have a good surge protector. at home i would recommend a power conditioner to fully protect your gear
A surge protector won’t do shit for a poor quality electricity supply, what you need us a decent UPS as most poor power sources either drop below or spike above their nominal voltage. But you know, they’re not the easiest thing to take to a gig 
And Makar1, forgive me for stating the obvious but when were you last struck by lightning at a gig? Oh that’s right, probably when you were doing some of these moves with your hands in the air:
I always use a 4-way surge protected extension lead at gigs.
It means I always know I’ll have enough (working) sockets, and as a surge protected one doesn’t cost much more than one without it, there’s no reason not to have that.
That’s what surge protectors are designed to do. Protect against voltage spikes.
A UPS isn’t going to keep the PA system going and there isn’t much point in just keeping the booth equipment going.
