One of Broome's most popular nightspots says it has had positive results since installing metal detectors at its entrance after a series of violent incidents involving weapons.

The manager of the Roebuck Bay Hotel Mike Windle says he has been shocked to find patrons trying to enter the premises with knives, scissors and even a machete.

Earlier this year, the WA Nightclub Association said there was no need for metal detectors after the Police Commissioner demanded clubs be forced to install the devices.

But Mr Windle says now that customers realise the detectors are in place there have been few attempts to bring weapons into the club.

"Gosh, I'd hate to find out what's out there, just finding out the little things that we didn't know about," he said.

"I'd say my message to the clubs in Perth or WA or anywhere would be to go onto the metal detectors straightaway."

Sergeant Simon Rimmer from Broome Police has welcomed the initiative saying more clubs should take their own security measures to limit violence.

"I think it's something that's fairly unobtrusive and I'm not sure of the costs that are involved," he said.

"I think a lot of patrons will respond favourably to it, knowing there is a venue that caters specifically to their safety.

"They may find themselves with increased patronage, which obviously offsets the costs of paying for these metal detectors."
