Buzzers, battery holders, and power cabling for Geotech ET and ETL water level meters.

Which buzzer?

The two are not interchangeable — they run at different voltages:

• Buzzer, 9–12 V — for ET meters.
• Buzzer, 3–24 VDC piezo — for ETL meters.

Also here

• Battery Holder, 9 V quick-change pocket — fits ET and ETL. Worth replacing if the contacts have corroded; intermittent power reads exactly like a failing control assembly, and this is a fraction of the cost.
• Power Cable Assembly, electric rewind — the power lead for electric rewind reels.

Before replacing electronics: fit a fresh 9-volt battery and inspect the probe and O-ring. Those account for most "dead meter" calls we take.
