Well made SMB. Easy to inflate and deploy. Just as I expected with Hollis gear!
The Hollis Signal Marker Buoy (SMB) is a great safety device that all serious divers carry on every dive. The SMB is the smart way for a diver to mark their location when making safety stops, completing mandatory decompression stops and signaling the boat if they surface a distance away from the boat. The Hollis SMB is brightly colored for easy recognition from a distance.
Buoy is a closed cell design made from durable 300-D polyester material with radio frequency (RF) welded seams. The SMB is equipped with an oral inflation and quick dump valve for total control of the Device. The Hollis SMB also has a sturdy nylon webbing strap loop with a stainless steel D-ring for attachment to a reel or anchor line along with a wrist lanyard for handheld use.
This product can only be shipped to U.S. addresses.

whats the width of this device?
TOM H
Approx 6 inches wide To clear up other questions you can inflate with the oral mouth piece and or the bottom flap that has a one way check valve, with your regulator exhaust or purge. This is a very nice SMB

The closed cell means that it cannot be filled from the bottom via air vented from a regulator. It must be filled by either disconnecting your LPI hose from your BCD or by oral inflation. Some people (Tech diver) like to be able to use the vent from their primary reg to inflate the SMB as it conserves gas by using the exhaled air, this cannot be done on this type of SMB. Orally inflating an SMB requires a person to remove their air source from their mouth and some schools of thought believe this to be a risky practice (especially with novice divers)

The bottom is not open. Good because it will not leak out the air. Bad because it's a little harder to fill.
