Proton T4

The Proton T-4 produces a bi-directional field which provides a 20,000 Gauss positive field and a 20,000 Gauss Negative field. This results in a field spread of 40,000 Gauss (4 Tesla). The T-4 achieves this by using a unique, patented "Reverse Polarity". Other degaussers may have either a positive or negative pulse, but only one. The T-4 has both and it is fully automatic. This ensures complete and permanent erasure of your data and protects your sensitive information. The T-4 will not be outdated soon and will degauss your magnetic media for many years to come. No other degausser compares!
