Capry -
The article was clear that it was an ELT, which floats, sends a radio frequency beacon, and is detectable by satellite, unlike a ULB.
They are using the ELT to focus the search for the ULB.
There was no indication of when the ELT beacon was detected, but the PMS Burullis made a bee-line to their search location immediately after the crash.
