The innovative 3 kHz coil from AKA developers is tailor-made for deep search operations, particularly targeting large objects. This detector is highly favored by treasure hunters and WWII relic seekers alike. Its elliptical design allows for extensive coverage and precise detection of sizable targets. However, its low frequency renders it ineffective for smaller items such as coins and tokens. Like many detectors, the AKA 3 kHz coil can be susceptible to electromagnetic interference, especially in cluttered environments. Remarkably durable, this coil can withstand light impacts, reducing false readings significantly. In terms of depth capabilities, this low-frequency detector boasts impressive accuracy: detecting a 10 kopeck coin from 1837 at a depth of 40 cm, a copper button at 30 cm, and a silver artifact at 25 cm. For those seeking Catherine’s 5 kopecks, depths of up to 60 cm have been achieved with this remarkable coil from AKA metal detectors!
