Easyfisher EFU-1 Electric Fishing Control Unit

The Easyfisher EFU-1 Electric Fishing Control Unit was designed completely in-house by East Anglian Electrical Services. Design of the unit was undertaken from the outset in close collaboration with senior members of the Environment Agency's fisheries department, who issued a list of requirements that the unit had to meet. Chief amongst these was vastly improved reliability and longevity compared to units that had been supplied to the fisheries teams by other suppliers.

The testing and evaluation of the EFU-1 prototypes was closely supervised by members of the EA staff, including technical staff and the principal electrical engineer. This included the demonstration of various protection mechanisms that had been designed into the unit to prevent its failure in the event of operator error, such as shorting the electrodes together.

After conducting their own tests and examination of the prototypes, EA staff gave their approval of the design. This enabled EAES to finalise production details of the unit, such as gaining CE certification from an accredited test house. Production of the EFU-1 commenced in the autumn of 2010. To date, over 30 sets of equipment have been delivered to the EA's fisheries teams.

The Easyfisher EFU-1 Electric Fishing Control Unit has been specifically designed to meet the Best Practice Guidance for Fish Capture by Electric Fishing to achieve the optimum combinations for efficient fish capture and fish welfare under the range of environmental conditions encountered by fisheries staff. Feedback received from end users indicates that the equipment is proving reliable in operation. We are confident that the unit will perform reliably and warrant the unit for a conditional 3 years.

The Easyfisher EFU-1 electric fishing control unit has been designed to be as user-friendly and intuitive in operation as possible, whilst maintaining high levels of reliability and operator safety .A monitoring and control system using twin microprocessors continuously checks the operation of the unit and inhibits all fishing outputs if any abnormality is detected. A fault reporting system alerts the operator to any faults detected by the monitoring system.

Up to ten different fishing profiles may be programmed into the unit. Each fishing profile has voltage, frequency and duty-cycle parameters associated with it. Once a profile has been programmed and stored, the settings of its parameters are retained in memory until reprogrammed. Any profile may then be easily and speedily recalled for use. A large illuminated display panel mounted centrally on the unit's front panel provides a comprehensive indication of the unit's current status, including output settings and output current. The output current indication is presented both graphically by means of a bargraph display and also numerically. This aids readability at a distance.

The unit is programmed by a series of simple steps using four large push-buttons, which have been chosen to provide good tactile feedback and to allow easy operation, even by a gloved finger. Three daylight-viewable LED indicators also provide at-a-glance indications of basic unit status and an audible alarm provides additional useful feedback of the unit's operation and draws the operator's attention to any problems which the monitoring system has detected.
