Review Adjustment screw for Halcyon Focus 2.0 with Explorer Handle

[datth]

If you're like me and dislike the collapsible delrin handle on the Focus 2.0, the Thumb Screw Set for Light Monkey's hard goodman handle works just as well on Halcyon's metal Exploration Handle. They're the same thread size, I think 6-32. It makes the handle more collapsible for transport and adjustable anytime. The tiny phillips head screws that come with the handle is flimsy, easy to rust, and difficult to adjust without tools.

DRIS (Dive Right in Scuba) has it tax free and no shipping fees (if you buy enough) if you call them with part #10.301.004. That's where I got them from. You can add some copper anti-seize or something between the threads of the stainless steel screw and the aluminum handle to prevent galvanic corrosion so you can easily undo if necessary.

If you have a McMaster-Carr account, these should also work:
1) McMaster-Carr
2) McMaster-Carr
3) McMaster-Carr

Hope this is useful.

Update: Thread size of the screw is 6-32, for those who are curious.

I’ve had those style thumb screws come loose on my light monkey lights way more often than I’ve had the Philips come loose on the focus.

On the other hand, I have had the Phillips ones come loose on my Focus a few times, very annoying under water. Even if the thumb screws loosened, the fact that I can hand retighten them underwater makes them better.

If you add a very thin washer like I did (look at the above picture) and/or use Loctite blue threadlocker, it won't come lose at all. Even if it does, you can easily tighten by hand.

Loctite + screw driver and they don’t come loose versus having to tighten them underwater a few times a dive…

Putting thread lock kinda defeats then purpose of trying to make it easier to adjust. I used a bit of Teflon tape for a while and that helped
