    Anybody out there know if you have to have the honker underwater in order for it to honk? It just doesn`t honk. I had it on a tank and tried it at 500 and breathed it down to 200 and no honk. I did not have it in water though. So...….does anybody out there know if that is necessary or if there is something I can do to get my honker honking. Thanks in advance!

    No. You don't have to have it in water.
    But stand by.
    I'm close to posting a thread on how to restore the Honker, with lots of pics and oring recommendations.

    I have one I need to rebuild, too.... So I will be waiting on @rsingler to show the way!
    This place is an unreal source of knowledge.
    Respectfully

    I used VDH`s rebuild kit and followed the very shaky video he tagged with it, so all o-rings are good and IP is locked at 130 give or take a few. So like James79. I anxiously await your posting.

    Looking forward to the post. Have one of these I've never put in the water.

    I figure if I get mine working right, then if one of the kids ever goes low on air due to complacency it will make a great corrective punishment! Audio warning, and a heavy as hell!

    Just cuts down on the weights you have to carry!

    Eric uses 2 pounds with a neutral bpw (cutting board mk2) and an old school 72... Throw in the mk7 and he might get rid if lead altogether!

    I tend to be leg heavy in tropical trim to the point I've used 1.5# leg weight on the top of the tank. MK7 might do the trick instead.

    As a teaser (sorry!), I've put the first couple of posts for the restoration thread in the Repairing Your Own Gear forum here:
    How to Restore a Scubapro Mark VII Honker

    It's a work in progress, but I wanted you to at least see that I'm getting close...

    To answer @Perryed , yes! The Mk VII honks out of water. It's even worse underwater, lol!
