As for Camo wearing people, my personal opinion is that some people think of it as -
work wear in the bush
weekend warrior, therefore camo clothes
a form of outdoor uniform
past or current military service
hunt with it, so detect with it
Just about wear it EVERY day ( I used to, I was 18 then )
deliberately dont want to be seen so well
And a few other reasons.
BUT the more mature person thinks of visibilty in case of injury, becoming lost, seeing/finding each other and/or shared use area's like bush walking and hunting.
Detecting is very much like hunting and because you venture into places not well known, you have to be responsible
enough to be able to save your own bum, someone else and to make it as easy as possible to be recovered in case of a search and rescue.
Notifications, checkin times, mapped zones, Sat phones, PLB's, GPS, UHF close comms, first aid kit, more than adequate water, fire source, survival blanket, and FOOD
Map reading skills and a compass, some GOOD basic bush skill and survival training.
A list of this with a station owner too.
A lot of this is so easy to get and not expensive compared to your hobby costs and your life, can save your bum and make it easy to recover you.
A car doesnt fix it, if it dont work.
AND I am sure property owners/managers like MT would welcome visitors half as prepared as above.
Sadly it is so simple to achieve. You dont need it all but some of my list is not negotiable on 1,000,000 acres of country, tropical or dry red desert.
Scouting Motto - BE PREPARED, I never forget it.
