custom Z-Sleeve

"Z-Sleeves are not ferrite or resonance control based. Rather, they are designed to approximate a Zero Gauss Chamber. The tube creates an internal magnetic null area that completely obliterates EMI contamination. This is accomplished through the specific combination shielding materials dimensional ratios and increased abilities of those shields to hold and store EMI." M.H.
