Field Test of the TRX tether ring

I have had the Whites TRX tether ring designed for a month now. Unfortunately I do not own a TRX so I cannot test it out in the field. 
This weekend the first prototype will be in Mississippi in the hands of Mr. Kevin Strahan for a two day shake down of this new design. I can't wait to get his feed back so I can finalize the design and make them available to all TRX pin pointer users.
The tether ring on the left fits Garrett, Minelab and Deteknix x pointer. The one on the right is the one that will be tested on the Whites TRX pin pointer.
