G'day EAF, Welcome to the site. That looks like either St Heliers or Kohi. I am originaly from Glendowie. Looks like a Garrett weapon you have there, I use an older Garrett Treasure Ace 300. Pretty much just a switch on & go machine. But I have found a shit load with it. Can tell 9 times out of ten what coin I have before even digging it up. Well that was before the new coinage came out that has(can you believe it)IRON in it. That sort of up set the discrimination ability as I am sure you will know about. Has a good discrimination & ID on it. Went out on the beach here in Whanga just the other night for half an hour. First time in ages & found a few $1 & $2 dollar coins & a nice mans silver ring.
Here are few pics of some of my finds on beachs & parks over the years.
Silver rings on the left
Coins, sinkers & odds & ends
gold & silver rings & gold bracelets
Detecting around an old miners hut ruins down south.
And what I found. Just junk really
But then found this 1884 one penny.
Good to have you on board & hope to hear of some of your advantures & finds.
Happy hunting
JW :)
