For those that saw the Tethrd Phantom at the 2020 ATA show and wanted to get an amsteel prussik bridge(the main difference on the phantom), it can be done.... for about $20
What is needed--
10 FT 1/4 in. amsteel
4 FT 3/16in. amsteel
How to do it--
With your 10FT 1/4in. amsteel --splice a 3inch eye within your harness loop; you will need to splice this 10ft piece directly in the middle (5 ft in) because you will have to bury your end through the difference of the rope.
once you've spliced your eye and buried your end you will end up with roughly 4-5 feet of rope. Only roughly 25-30 inches will be needed, so make a stopper knot and cut the rest off.
This will be your bridge.
With your 4FT 3/16 in amsteel-- wrap your 3/16 around your bridge and create a prussik, tie this off on the harness loop on the opposite side of your bridge.
The outcome is as follows
