CZ-21 Tone ID Question

#1
I am going to hunt tomorrow for a friend of mine's platinum wedding ring. He lost it a few weeks ago in a shallow pond that is on his property. I have found silver rings and gold (yellow and white), but never a platinum ring. so, Can someone tell me what tone I should expect to hear when the coil crosses over it? High, Medium or Low? Thanks.

It's been a while since I hit platinum with the CZ-21 but if I remember correctly it should come in the gold range. With my Excal 1000 it sounded in the high range unless it was a platinum/gold diana ring.
Good hunting to you and I hope you find it, platinum is so dense it tends to sink deep fast.
