Sniffing out crime and recidivist offenders were Tasmania Police's key priorities during a northern suburbs lock down on Wednesday.
The state's four police dogs worked alongside officers to detect guns and drugs at Ravenswood.
There were 580 random breath tests conducted with two drivers found to have illicit drugs in their system, two people charged with unlawful possession of property, four people on fail to appear warrants arrested, two people charged with firearm offences and a person arrested in relation to a family violence investigation.
About 30 officers were involved in the operation on Ravenswood Road, near the Lambert Road intersection.
Police Inspector Brian Edmonds said the dog-handling unit was called in to assist with the crackdown.
"We've bought in ... three drug detecting dogs, and one firearm and explosive detector dog," he said.
"I've been working alongside our drug dogs ... and simply by opening a car door the dogs are very good at getting an indication as to whether or not drugs are involved."

Firearm-detecting dog Olson is normally based in the state's North-West, conducting searches on the Spirit of Tasmania, but he spent Wednesday sniffing around Ravenswood.
"We've prioritised the use of that dog here today in response to the issues that have been going on in this Launceston area," Inspector Edmonds said.
Olson had a busy day with Inspector Edmonds saying a number of guns were located.
"The firearms involved are still under investigation, but they range from 12-gauge shotguns through to small and large calibre rifles," Inspector Edmonds said.
Ravenswood resident Margaret Briggs said seeing the police operation made her feel safe.
"They should come up here more often," she said.
Ms Briggs hopes police will run a similar operation in the area at night.
Operation Orca, previously known as Operation Raptor, conducted a similar crime crackdown at Mayfield in May. Acting Sergeant Aziz Melick said the taskforce was trying to make the lives of recidivist offenders as uncomfortable as possible by arresting and closely monitoring them.
Prior to Wednesday, the operation had arrested or charged 145 people with more than 640 charges laid and seized 13 firearms.
