INON Z240 design

Having jumped from the boat and descended to 12 meters, I noticed that my Z240s weren't firing up. Immediately I knew that I'd jumped in with the battery compartment completely open and the batteries still in the charger on the boat.

I came to the surface, rinsed the compartments with fresh water and dried out thoroughly. Praying I put the batteries in... and they still work!

Thanks INON for separating the battery compartment from the internal components!

I was once almost finished on a dive, glanced at my strobe and notice a small stream of bubbles coming from it. The batteries had decided to offgas and extruded the o-ring out.

As above, quick rinse with fresh water, dry the contacts and all working again

Now if only someone would invent the stoopid factor strobes that wack us in the head when we forget things like battery caps and o-rings!

My wallet reminds me of my idiocy from time to time!

I can beat that. Today I put batteries in my SB102 for the first time in 18 years. And it still works. I may dive with it at the weekend and rest the Z240s!

Meant to ask, were you going for the crabs?

Alex

I wouldn't count on the integrity of the battery compartment. A few years ago I went in with the o-ring out of alignment and water got into everything, beyond redemption.

Phew! Got to love a good dodge.

Ken what depth did you take yours to on that fateful dive?

Cheers,

Last year in Lembeh, I had a hair on the battery o ring.

It flooded the entire strobe.

The battery compartment is not sealed!

Mine seems to be, I went to more than 10 meters with the battery compartment completely open!

Okuma & Alex,

What are the model numbers of your respective strobes (e.g. type III or IV)?

Bob

The Inon battery compartments have always been sealed, but floods do commonly blow past the o-rings on the terminals and damage the flash circuitry. Water on batteries produces lots of nasty gases, and the explosive pressure in the battery compartment can overcome the effort made to seal the batteries from the rest of the strobe.

Maybe because I had no batteries in at all, this was the saving grace! Type Fours!

Okuma & Alex,

Bob

I purchased a group of 5 from Reef about 6 years ago.Type III

The remaining serial numbers are: DB281728, 41, 58, 72.

So I assume the leaker is in the same general series.

Translation: it's better to forget the o-ring, and flood the battery compartment, than just wet the batteries!

Isn't life subtle, and misleading?

Or if you're going to forget the o-ring for the battery compartment... remember to forget the batteries as well!

Or forget to take camera with you!

A friend of mine drowned an Inon 240 last week and it didn´t seem to have a sealed battery compartment as YS250s for example...

He will be remounting it today to see if it works but does not look good...

Or if you're going to forget the o-ring for the battery compartment... remember to forget the batteries as well!

But, if you are going to forget the o-ring, you can actually take the batteries with you as the gases will be able to expand free!

This is all a conspiration to make us return to natural light photography!

I don't think global warming creating more clouds will be helping us with natural light

Remember that we now have access to high ISO cameras
