Probably because I linked directly to the post in the vets section. Attached here instead.

Note, this was a one off, don't think any further development happened after this. Not the most practical of designs, although it certainly has the "cool" factor.

Yeah thats what I meant when i said ring. I saw it. But wasnt sure it was a thing.
I really feeling out of my depth on this forum. Its very highbrow. Cant really contribute much.
Already been called a troll,im not fussed but feel like Ive walked into a science convention. Still i'll persevere for now see how it goes. Once I get to use the arctic I might try posting some photographs (dont know much about photography either) :crackup:
