Metal detectors with a low charge indicator
Low battery indicator
— an indicator that signals the imminent exhaustion of the battery and the need to charge it or replace it with a fresh one. This feature reduces the risk of being without power at the most inopportune moment. However not all models provide an automatic signal of a critically low charge — in some devices, the user himself has to periodically check the indicator readings.| low charge indicator | clear | Save List |
