I have a pair of Peltor Swat Tacs; they are great. I have not actually competed with them, but I bought them on the recommendation of several shooters who had.; one had used them in service and said they hold up great under the carppy conditions he had put them through.
ProEar is the way to go. I had done quite a bit of research and the tecnology is different with Peltor. Peltor and most other ear protection(Electronic) tends to shut off when there are loud sounds.
I am not in any way related to this company or brand. I am using it's Pro Ear Predator 300 series and I can hear everything going on at the range.
Posting this just to help you guys to hear better and safer at the range
Here are the details from their website:
A. We are the only company to offer true, Dynamic Level Sound Compression. While others claim to offer "Compression Technology", they are in fact offering old technology such as "Peak Clipping", which merely shuts off the electronics when presented with a high noise level or "Automatic Level Control", which reacts to high noise levels by lowering the volume. "Peak Clipping" just turns the amplification off so nothing is heard. ALC does not 'compress' the dangerous sound levels during an instance of high sound levels is defeated. Only Ridgeline's 'DLSC' technology protects hearing while at the same time allows the wearer to hear lower sounds. DLSC instantly reacts to 'compress' all noises over the 70 dB threshold by 50% to a safe level and amplifies all sounds below that to 70 dB.
B. Our Attack/Recovery Time is the fastest in the industry at 1.7 milliseconds. Others are as long as 20 milliseconds.
C. Our sound quality is the clearest, most natural ever offered and you can tell the difference as soon as the units are turned on. While others sound 'tinny' or 'muffled', PRO EARS are clear and natural.
D. Each cup has its own set of independent electronics and controls so each may be adjusted separately. This eliminates the need for connecting wires running across the top of the headset to snag or break.
E. We use a lighter, smaller, less-expensive 'N' battery that provides longer life than the 9 volt, AA or AAA batteries used by our competitors. PRO EARS get a minimum of 200 hours battery life while some competitive products get only 45 to 50 hours. The reason for our longer battery life is due to the superior Surface Mount Technology of our circuit boards and the fact that we have no power robbing wires running across the top that cause electical resistance.
The Peltor Tac 6 uses 'Analog Peak Clipping' technology, which is a technology that's been around for many years. When sounds/noises exceed 82 dB around the user, the Peltor Tac 6 circuitry shuts down(off) electronically. The circuitry will not return to normal operation until the sound/noise level drops below 82 dB. The Attack Time of this unit is 5 Milliseconds. The effect is a clipping on and off. At a shooting range or any area which has a high noise level, the unit will be constantly turning off(clipping) because of this high level of ambient noise. In fact, if the ambient noise level exceeds 82 dB, the electronics simply stay shut off.
The Peltor Tac 7 uses the same circuitry discussed above, only with a single volume control that is connected to the opposite ear cup by a wire. The obvious disadvantage of this arrangement is adjustability of both sides in the event the wearer has hearing loss in one or both ears. The attack Time is 5 Milliseconds. Battery life is 45 - 50 hours max.
Silencio uses the same 'Analog Peak Clipping' technology as the Peltor units. There are, however, a few difference. Most notably, the Attack time is 20 milliseconds...ten times slower than PRO EARS. Note that the 20 millisecond attack time occurs at the beginning of the shut down as well as the recovery time. The threshold for responding to a loud noise is 90 dB, well above the danger level.
