Any specialist with theories?

​Hi everyone! I’m a solo developer and a fellow dirtfisher.

​I wanted to share a quick video of an Android app I've been building called CoilTrail. I just updated it with a "marker clustering" feature. Basically, if you have hundreds of finds in one field, it groups them up so your map doesn't turn into a laggy mess, and splits them apart as you zoom in.

​More importantly for this group, I managed to integrate high-res LiDAR/Hillshade specifically for England. You can use the slider to fade it in and spot old earthworks and pathways right under your pins. The whole thing works 100% offline so you don't need cell service in the field.

​I’m still developing and improving it, so I would absolutely love to hear what the UK detecting community thinks!

​You can find it on Google Play here: https://play.google.com/store/apps/details?id=com.niittyproduction.coiltrail

Just to be fully transparent with the community: the app is free to download and play around with, but the heavy offline maps and UK LiDAR require a Pro subscription (there is a 7-day free trial). As a solo dev, offering high-res data offline means I will quickly hit paid API and server limits as more people use the app. To keep this project sustainable in the long run without stuffing it with annoying ads, I had to put the heavy mapping features behind a subscription. Hope you understand!

Found this old bottle stuck in the bank of the looking glass river in Michigan. Any help identifying it would be greatly appreciated, thank you!

Lower part of the bottle is embossed with Lansing Mich

I’ve never found pink before! Tons of blue today, and this really interesting bit that’s super dark but red when back lit. I swear that amber at the top is super orange in real life I feel like in this picture it looks like standard beer bottle orange 😂

I found this beautiful thing this morning and I’m struggling to ID it. At first I thought it was a coin but the reverse is completely flat.

Found this while larking today, it’s slightly domed like one side of a button and embossed with an anchor logo. First picture is the underside (the side embossed into) as you can see the anchor better. Anyone found anything similar or have any idea of age/origin?

Going through my maybe / junk box of finds from years ago and want a 2nd opinion on this before i throw it or keep it. Does it look worked or is it just a water worn piece of rock ?

Looks like its slightly worked along one edge but it could just be tumbling damage.
