AKA Signum overview

Signum sits in AKA's range as a long-range locator built specifically for teams searching large open ground. It's built around a detection depth of 5-6 feet and selectable multi-frequency operation from 30 kHz.

What separates it day to day is space-harmonic filtering (sft), hodograph target id and 1-30 khz multi-frequency range — details that matter more once you're a few hours into a search than any spec sheet line.

It's made in Russia, and comes with a 2 years warranty.

AKA Signum key features

Space-Harmonic Filtering (SFT)

patented signal-processing technology unique to AKA that heightens up target classification and cuts off-target readings

Hodograph Target ID

displays a spectral-graphic hodograph of each target on the 128x64 LCD for exact, visual classification

1-30 kHz Multi-Frequency Range

transmits and processes signal covering a wide frequency band for flexibility covering soil types and target sizes

Turbo Deep-Search Mode

an additional program geared toward locating substantial objects at exceptional depth

Triple Discrimination Algorithms

toggle between MSF, SSF, and MM modes to match iron-heavy, mixed, or open terrain conditions

Automatic & Manual Ground Balance

self-corrects for mineral-dense soil with adjustable readjustment speed, or can be set manually

Waterproof Control Housing

sealed electronic control unit with a rapid-release, tool-free coil mount for rapid field swaps
