In Topic: Best way to achieve tack sharp focus?

Try locking focus on your fin.  If you want to focus at 3 ft actual distance you must focus at the virtual image equivalent distance which is substantially less.

Take a look at these new lights.  I use the discontiued 800 for focus light & have been very satisfied with quality & performance.  The prices are far less than other popular options.

In Topic: Full service of housing

Internal o-rings (buttons & controls, etc) must be removed for thorough inspection, so you might as well replace them with new ones.  If you do muck diving the fine sediment will eventually work its way into the bores, making for a sticky button, so servicing will be required more often than a system that is only used in clear/clean water.  Before servicing make sure you have a complete factory rebuild kit including new c-clips.  The clips are fragile & may break on removal, so do not reuse.  Most of my diving is muck, so I usually have an annual service performed.

Tiger Beach is a shallow plateau away from the islands.  The leeward side can offer some shelter but it's not like being close to shore.  If it's too rough Jim will find a good place to hide.

For muck diving in general you will find a need for both 60 & 100 mm lenses.  Last month in Lembeh I used my Nikon 105 most of the time but glad I had the 60 for the paddle-flap rhino.
