Burke O’Neill, director of ETS Electrofishing , supplied the MBS-1DP-COL-SR high-peak current control box, developed by Colton Perna for Australian conditions. This unit is designed for nominal 240 VAC, single phase, 50 Hz operation, from a portable alternator – in this case supplied by a 6.5 KVA Honda from Powerlite – and is capable of delivering 4.8 KVA to the electrode system. Unlike the standard MBS-1D, the safety interlock pad/switch on the COL-SR may be used to directly switch the high voltage output on and off without resetting the front panel START/RESET button. In laymans terms, this combines with the full ETS volt and amp metering to provide more effective and efficient fishing than the 5.0 GPP Smith-Root systems. It’s also about 2/3 the price and user serviceable!
Colton Perna completed the wiring of the boat to meet the rigorous Australian standards (which I will post in our resources section the near future), with waterproof safety switches and the ubiquitous quick-release anode fittings. The anode themselves are a relatively new design aimed at eliminating the hassle of setting-up the industry standard Wisconsin arrays – droppers can simply be clipped on and off using the stainless carabiners to change electrode resistance. A new, finger-friendly system of anode attachment and rotation system, designed by Clayton Sharpe, is also fitted – instead of drop-in holding pins, two frilled circular plates mesh together under a large circular nut which can be adjusted while wearing gloves.
