Where does platinum ID on the GB SE? Thanks

I have no clue on that since I have never had any platinum items...
Platinum has low conductivity and is very slightly magnetic. In the form of a ring the magnetic aspect of the stuff won't have much influence. Most likely it'll fall in the foil range below nickels unless it was an unusually heavy ring.
In my opinion your best bet is to use the 5 inch coil and rely as much on the sound as on the ID. The ring (since it's recently lost, and shallow) will likely give a nice solid crisp response, whereas scrap foil will generally give a weaker and muddier response. ID on the ring will probably be quite consistent, whereas on foil or other low conductivity trash the ID will tend to bounce around more as you sweep from different angles, different speeds, and different heights.

Maybe someone with some actual experience with platinum rings can offer more specific advice.

I swing a GB Pro. In the attached photo is a Pt900 ring (90% platinum) with 18k gold accents. TID was 48, crisp n clear signal.
As you weren't specific about the kind of platinum, native platinum grains can sometimes have an iron coating built up from the passage of iron-rich waters, and that may cause the TID to register very low. I haven't found much and must say that my experience with native platinum is limited. Searching in all metals mode and digging up each signal is still the best, albeit most laborious route.

sounds like a good idea they would be highly polished? i am in Australia but NZ is a beautiful place might get there one day, but until then i hope to get out look for some bush nuggets 
just polishing some jewelry in the tumbler 1st time i tried doing them in the tumbler works very well am impressed just chucked some crushed granite and some water and bit of soap cleans up the silver great from the beach. looks like new !!
thanks too to Dave J for the input too on the bug and some hunting techniques.

Sorry Amberjack...dunno how it got into my grey matter that you were a kiwi. All I knew was that you weren't in the US. That's the problem with pondering multiple thoughts while reading a forum. Was thinking of my aunt who moved from Auckland, NZ to Sydney, Oz (before the quakes happened, thankfully), gold revealed by glacial movement and I must have got my signals seriously crossed while typing. Glad to hear that your tumbled silver turned out great. Don't forget to apply a barrier to prevent new oxidation!
Before me brain experiences flatulence again, one more thing to add to those who do happen to come across native platinum grains/nuggets: most members of the platinum family are malleable, so if your Goldbug honks @ 45-48 TID and the target doesn't stand up to a hammer, don't toss it yet! It could be platiniridium which is brittle.

no probs hobbyist i have been called worse 
just 
yes they did cop it over there with the earth quakes still getting tremors glad your aunt is safe.
what sort of barrier is recommended?
i have found some of those platiniridium nuggets but am pretty sure they are aluminum
where do they get found in with gold in the field cant say i know much about platinum.
would be interesting finding some of that stuff.

I don't have much silver, and usually after doing the aluminium foil/baking soda/hot water cleaning method, I just swab the dried pieces with Blitz Gold Care cloth. It gives decent protection against tarnish and oxidation. Have heard good things about Goddard products....you may want to try their Long term silver cloth.
Never found Pt and Au together before so I can't comment on that. The first time I came across grains of Pt was back in 2001 without a detector! Went to a stream to wash some dust and sweat off and noticed those gray grains by the bank about 3 inches in the water, one grain had a slivery sheen and they looked out of place against the red laterite. Monsoon rains do tend to wash out a lot of stuff from the slopes. Hey, if you get enough aluminium, that's money too at the recycler's!

i seem to find silver rings a lot, most from the water at the beach are black and take some work to get back to there former glory the tumbler is doing a treat on that so will have to get myself one of those cloths for sure, no one in my family seems real interested in jewelry so when/if i find a woman she will have fun going through my stash but she will have to be nice to get that far but that's a whole other story 
i save all the old keys locks sinkers and stuff like that but hadn't got as far as aluminium
wow that's pretty kool on the PT is it worth much in that form i have never seen it i guess we would have it here but wouldn't know where, we have every other mineral so will have a look at some maps see where it lives.

Dunno how accurate govt. maps are (the ones over here are largely crap): http://www.ga.gov.au/image_cache/GA6886.pdf There's a few Pt deposits near Munni Munni (an apt name for the place, homonymically speaking) There's virtually no market (read: premium price) in my neck of the woods for metals in native form...only melt value less buyer's margin.
Maybe someone can chime in with hints and tips on how we can locate suitable places to wave our bugs for this noble metal?

Hobbyist i think they are pretty good here thanks for the link will have a study when i get time but from what i can see it looks good where the is munni munni never heard of it with good reason i suspect in the middle of bloody nowhere i am guessing?
yes would be something else to have a go at would be kool to find some i hear they also find silver nuggets but from what i understand are pretty rare unless lots of jelly is employed but maybe that's harder to find than the nuggets
just heard from Fisher they are replacing my Gold Bug Pro, so a big Thanks to Dave J. and Fisher for looking after me
will make it official on the thread i started when i get it back and take it for a spin. i have missed it

I feel guilty...maybe we're hijacking the thread? My thanks to Pete4Au for his patience.
Munni Munni is in Maitland, WA. 2 deposits of Pt are in that area. Maybe you could get to swing a bug there and let us know the results? Yes I believe your govt's mineral maps are way better. Google Earth's a handy tool. Just type in the name of the place and away you go! BTW, there's a Big Stubby and a Woodie Woodie on the map...with a gully between them. LMAO! Must have been named by miners who were expressing their lack of female companionship.
Congrats on your replacement GB Pro! I'm happy for ya, and big kudos to Fisher/ First Texas for treating the customer right!
One more nugget (pun intended) of info to share: Copper iron sulphide ores (Chalcopyrite) originating from hydrothermal sources can give TIDs of varying degrees. Pieces smaller than your palm will be around 69 and massive chunks will register as 93-95. This is from personal experience, and yes the GB Pro handles volcanic rock in seawater very well indeed.

don't feel too bad people wonder in and out some never come back, i just annoy people mostly but i do care about giving the info as i see it 
look see I'm getting side tracked already.
maitland WA wowsers 4000miles from me and W.A is where most of the gold in nugget form is too well there and Qld and Vic, some in NSW where i am but not as much as the rest i mentioned.
missing women and beer by the sounds of it big Stubby would be a beer bottle, i don't drink which is my gift to the world bad enough without one
is this the stuff http://webmineral.com/data/Chalcopyrite.shtml sounds interesting

The forum's a bear to login to this evening. Yup that link shows chalcopyrite. I'm attaching a pix of a lump I found to let you know that mother nature does not always make homogenous items, and websites on minerals are good...as guidelines (repeat: guidelines) only. You will find much variation in the metallic composition of many ores. Note the copper-coloured "skin" contrasting with the brassy-gold colour within (and disregard the stained coral encrustations on the surface) Gold can be found in porphyry copper such as this and can be as low as 1.2 parts per million to 22% or higher of the lump's weight (giving Calaverite some stiff competition! lol!) Find a fist-sized lump with high-Au content and your machine is instantly paid for, with change to spare. I kid you not.
PS I don't drink too, so between you and me, the world is doubly gifted. Haha!

wow that's amazing stuff so much to learn and so little time, so that's found in volcanic regions? so it was just on the ground? or in the water? i love rocks and learning about them science was the only subject i liked at school but that was awhile ago 
so my brain is mush now and it's lost most info, i guess it's in there somewhere
what i want is a 4x4 Winnebago self sufficient with some sort of bike with motor to ride to the spots from the campsite and have somewhere to come back to that has all the mod cons, been in the city to long then i could explore and come back to a nice place to cool down or warm up have food and somewhere nice to sleep.
now if anyone wants to donate 200K or so to the dig please send too
need to be set up to go bush i recon roughing it well maybe for a few days at best...........

One of the Big problems is that gold does not seem to be in spots where cooling down happens much.
It seems to be in a lot of high heat locations......But tha'ts ok by me if the humidity is low enough....
