I love the Lightspeed Delta Zulu, and this one will be used by my wife as I already wear one and love it. After the first use my wife fell in love with the headset. Flying in Alaska, carbon monoxide is a real concern as we use cabin heat a lot of the year. I have had other CO detectors in the past, but you cannot hear the audible alert. Whereas the [Lightspeed] Delta Zulu the audible alert is heard in the headset. The HearingEQity is also a fantastic improvement for us aging pilots.
