The 8890 EMS (electronic marker system) is a special multi frequency marker localizer for the professional search. The 8890 can locate the 7 major utility markers – power, water, sewer, gas, telco, and CATV in one easy to operate unit. A scan feature allows the user to quickly identify any nearby marker and verify the frequency of each marker in the area. This is also useful for ensuring a marker is not misread.
