Lost my phone!
A trip to survey shrimp bone inlet, got part way along surveying only to drop my phone down a tight rift below out of reach. There was many expletives and failed attempts by me to retrieve it with ropes, bags and hand jammers. In the end I returned to the surface through the grade 4 like cave (2 x 40m pitches too) cut off a flexable tree branch and then returned to the cave with said branch and managed to get it to the location of the lost phone. With this I managed to retrieve my phone and by this point the rest of the team was done with surveying and I headed out again.
Branch remains as a way marker.
