Got my new HOG reg yesterday and dove with it today. Overall I am quite happy with it. Seems well built, breathes really nice (keep in mind however I don't have tons of experience, for this comment and everything below as well just to be clear).

I did however have an issue while diving with the purge button sticking on the backup. I was at about 35 feet and decided that I should try switching back and forth to ensure I was comfortable using it (it is on a necklace which I am still getting used to as well). I had tried it on the surface prior to diving also. The backup free flowed at depth for about 20 seconds, I got it to stop and went back to my primary reg.

I got very near to shore and thought I might try the backup again and this time she free flowed like crazy and I could not get it to stop. Ended up having to shut off the tank. The issue turned out to be the purge button itself was sticking. I had a look at it back at the truck and thought that maybe I got some sand in it or something else. This was not a typical free flow at the surface situation but an actual button sticking.

Just took it apart at home and no sand to speak of in it, there was a minor amount of grit above the diaphragm but not in the button cavity itself. I totally cleaned it up so there was no grit anywhere in the reg. I then fooled around with the button a bit, tried seeing if I could make it stick in a non diving situation when it is totally clean. Sure enough the button would stick if I pushed on it on an angle at a particular location...

I then took an Exacto knife and some 600 grit wet sandpaper and proceeded to "tune" it up a bit. I ended up shaving a very slight edge off of the four retainers that snap into the hole in the front cover as well as sanding the edge smooth of the button itself. I now cannot make it stick at all now and seems much much better compared to earlier.

Question to the board is has anyone else had trouble with the purge button sticking? I believe that I have fixed mine. I would consider this a very minor issue that was easily tuned up in about 10 minutes. I am diving in a pool tomorrow so I will have one last chance to try it in the water before I take off to Cozumel Saturday. All comments welcome. I believe now I will be very happy with this reg and will keep you all posted.

I have not had this issue from manufacturing perspective. A dive op decided to handle my gear after instructing them not to and the ended up damanging the same purge button beneath a set of doubles but HOG did send me a replacement which I'm eager to go dive with now. Besides that incident I haven't had any issues with the purge button on both my HOG regs.
 
Well I had a chance to dive for over an hour in the pool tonight and I had no issues. I did everything I could to try and make it stick and no issues. So this may be a case of one being a bit out of spec? Anyway works great now, breathes really well especially when you open it up. The End.
 
Brilliant. Job well done.

I port and polish all my stuff because of that stuff.

Often there are excessive mould split lines and sprue remnants all over the place.

Just operated on four seconds from another manufacturer with separate plastic rings and faceplates being metal and plastic, identical bodies.
When they decided to incorporate metal faceplates in their models using the same other parts the ring would sit about 1/5" shy of the body.

Much circular different grade wet and dry motion on the bench.

Cool.
 
I'm about to buy a HOG regulator. What I want to know is, are these easy to get serviced, and most importantly, do you recommend buying one?

Its easy for me to get serviced. I cave dive with them if that answers your question.
 
Dove the Hog on eight dives this past week in Cozumel to a max depth of 120' on did not have any issues. I am now quite happy and due to a shipping delay I ended up with two sets which I then decided to keep the second set. Not for free before anyone asks ;-)
 
The great feedback from owners of HOG regulators, and the company's attitude about making service kits available to users, are reasons I'm considering selling two of my Scubapro Mk25/S600 regulators. I want to start servicing my own regs, so parts availability is a concern.
I've been giving serious consideration to just switching over to HOG regs for doubles, singles, and deco regs. As I am needing more regs, the need for standardization, and being able to service them myself is becoming more important.
I have a good friend that will show me how, in addition to getting the appropriate tools, books and manuals.

We have 3 1st stages and 4 2nd stages with about 60 dives on them - no problems at all.

About to by another complete singles set (so I don't have to break down the doubles set) and a stage bottle set.

Go ahead, you wont be sorry! :D
