1.0 OVERVIEW
The EdgeTech 5112 Ropeless Fishing System (RFS) was designed with fishers to eliminate the need for a
persistent vertical line to connect fishing gear to a surfaced buoy until just before retrieval. The intent is
to alleviate possible whale and other marine-life entanglement and help prevent line tangles, cuts, tipped
cages, and other adverse effects of seafloor to-surface lines.
The RFS consists of a modified fishing cage with an attached EdgeTech 5112 rugged acoustic release with
transponder, a BLEAT (Bluetooth® Low Energy Acoustic Transceiver) Deck Box unit or a Portable BLEAT
deck box connected to a hull-mounted or portable dunking transducer and the EdgeTech Trap Tracker
application running on an iOS or Android device. The system is deployed like any other rope-and-buoy
cage, independent or at the head or tail of a line of unmodified fishing cages. The cage contains the 5112
release with transponder, rope, floats, and an attached NFC (Near Field Communication) tag.
5112 Ropeless Fishing system operation is straightforward. Commands are made in the Trap Tracker
phone application, sent by a Bluetooth® wireless connection to the BLEAT deck box. The commands are
interpreted, and an attached dunking or hull-mounted transducer sends the commands via an acoustic
signal to an in-range 5112 release attached to the cage. The release receives the command, acts, and
replies to and with information to the Trap Tracker phone application through the same system.
Commands include ID information, status information, and recover. Cage recovery is accomplished by
sending a unique recovery command to an in-range modified cage that responds by sending range
information to the phone application and mechanically releasing the line and buoys to the surface. The
line and buoys are retrieved like any other Trap. Trap Tracker collects and stores information during the
entire process to help fishers make decisions in the future. This includes underwater unit information,
real-time status information, and user-added operational details.
