appropriately correct the duration of impulses increasing their
length. This is done by the Power knob.
Power of output impulses influences exit of fish in lesser
level than frequency. If the power is high the fish will start flowing
up from deeper water and sinking afterwards. Too little power
level will cause that fish will escape immediately if the electric
field is not enough to shock them and if you press the button
START for too short time. Between maximum and minimum there
is an optimum level of power which allows, from the point of view
of smooth exit of fish, to catch them as effectively as possible.
However, this level should be closer to minimum than maximum
to keep the battery work longer and cause less stress to fish.
During electrofishing it is possible to take two ways of fixing
output power: medium power level and periodic pressing the
button START ( no longer than 10 seconds); low power level and
longer pressing the button START. In the shallow waters the
power can easily be reduced to as low as 50.
