The rugged design and quality construction of Miller Helmets result in a lifetime of service with minimal maintenance. The Series 400 Helmet provides maximum head protection, excellent mobility, and balance. The helmet moves with a diver's head as easily as a mask. It is secured with an internal adjustable, padded neck strap and fits all head sizes.

· All the helmet shells are solid cast bronze. The standard Miller hat is covered with a black epoxy coating (shown above with optional face guard). They are also available as a special order in a highly polished bronze (shown at left with optional face guard). The finished helmet weighs approximately 27 lbs. and is neutrally buoyant.

· The communication system consists of binding posts, microphone, and two earphone speakers. The chin strap provides more comfort and improves diver safety. The chin strap works with the head harness, oral nasal, and face seal.

· A jam proof locking neckring adjusts at the helmet's base for an effective water tight seal. The neckring easily mounts on most dry suits.

· Two adjustable exhausts, one on the helmet and one on the regulator.

· Compressed air, mixed gas, and saturation capability.

OPTIONS & ACCESSORIES:

A Miller Double Exhaust Kit is available for the 300 or 400 series helmets, allowing for contaminated water diving. The Double Exhaust is designed to be used on modified freeflow helmets only. It is necessary to remove the demand regulator before installing the kit. Plugs and covers are provided for installation in place of the regulator. Maintaining over-pressure within the helmet and suit by use of the free flow valve should prevent back-up water entry.
