In 2010 the team explored a total of 3650m of submerged tunnels in Sump 3, to a maximum penetration of 2965m (-40m) from Tipperary. A total record breaking distance of 8825m of diving.

In 2011 the team passed Sump 3 after 3275m to find an active streamway with numerous cascades leading to a fourth sump. To reach this point 9135m of diving was required from the entrance.
