My rigger added a webbing "hard point" on the left riser cover of a
couple of Mini Softies. The cover is only sewn to the harness on the
inside, velcroed on the outside to allow riser deployment. Position is
about perfect for the SPOT 1 that's on each. Best mount I found for
the older SPOT uses a modified pouch that Wings And Wheels used to
sell for the EBC 102 Personal ELT.
The SPOT 2 has it's own pouch so should be easier to mount on the hard
point.
