From the people who carried HEED.
Excerpts from letters shared by helicopter crew members and rescue personnel.
“Your product, Helicopter Emergency Egress Device (HEED) was instrumental to my safe egress that day.”
“The pilot (right seat) and flight mechanic activated personal HEED bottles located in their survival vests and successfully egressed from the wreckage.”
Included: holster and mouthpiece cover. Refill adapters are optional and included only when selected. The nose clip is available separately.
A closer look at your setup.
See how a hose model can sit on a compatible flight vest, and how compact the cylinder is in hand.
A few things to know.
Which refill adapter should I choose?
Match the adapter to your model and filling source. The HP-4500 requires its compatible high-pressure adapter; do not assume an adapter listed for another series will fit.
Can I order a pre-filled unit?
Where offered on the product page, pre-filled shipping is an additional $15 and is limited to contiguous-US ground delivery. Otherwise, the unit ships empty.
Where can I find a compatible vest and accessories?
View the SWITLIK X-Back vest and the nose clip with lanyard. Confirm mounting compatibility for your specific equipment.
