You have any info to what study found the deterrents ineffective to a great white in attack mode?
I personally think this this whole thing is getting blown out of proportion. Since 2000 there is less than 1 fatality a year in WA. I don't see this apparent incredible danger.
i cant recall the link but it was for the sharkshield version (supposedly the best option) and reviewed several studies in south africa and south australia by UWA. I think it was referenced in an earlier thread on sharks here if you search it. The south australia study was labelled "inconclusive" but the scary thing for me was in 30% of cases it appeared turning the thing on actually provoked an attack in some large (4m plus) females!
No i dont think its an overdone risk if you are a regular surfer in either the south west or south coast. Think about it - maybe we are talking a regular population of "risk takers" of say 20,000 people (being pretty generous here to include people coming down from Perth) with an average of 2 fatalities per year more recently thats a 1 in 10,000 chance you will eventually die from shark attack in WA. Far higher than the risk from car crash where we spend 100s of millions trying to make people safe so $200,000 on unproven deterrents is a real cop out by McGowan IMHO
