A combined water field strength and conductivity meter. The meter is intended for use with a separate electroshocker for use in a body of water to produce electrotaxis in fish in order to collect the fish. The meter includes a conductivity probe which is placed within the water. Pairs of electrodes within the probe detect water conductivity and the voltage potential produced by the electroshocker. A processing unit applies and measures a known current between the first pair of electrode and measures the voltage potential between the second pair of electrodes. An LCD display connected to the processing unit displays the results so that the electroshocker may be optimally adjusted.
