Diving with FINN LIGHT torches

There are experiences with torches with revolving head type of switching from the time of the first backup torches like Halcyon Scout. This system is being used by more producers, more or less successfully, depending on the manufacturing quality. It is very simple to use, maximally reliable, preventing accidental switch on/off and allows using minimum of defective parts. Talking about backup torches, safe application depends on the depth since the hydrostatic pressure works on the thread. Therefore it may lead to a fatal situation, which I have gone through, when a diver cannot switch on his backup torch after the main torch’s malfunction.

Surprisingly, there are still very few main torches with this type of switching and they occurred only quite recently, e.g. Salvo Rebel LED or Dive Rite. Yet for a main torch this system is very suitable because it eliminates malfunction in a depth by wrong manipulation by its user. He/she soon gets used to a habit of switching the torch before the dive and letting it on during the whole active part. Logically, this is the safest way of manipulation with a diving torch. Especially, when you use it for communication with your buddies during the dive.

I have dived with the new FINN LIGHT torches on many different locations and here are some brief conclusions:

On principle, I always switch on any type of a main torch before the dive. So it cannot happen to me that the torch would spontaneously switch off during the dive (if it is properly recharged). I consider it a goof to find out that the torch cannot be switched on as late as during the dive.

On Czech locations such as Slapy, Orlik etc., the visibility during a clear day is about 10 metres deep. Here I switch the main torch off on longer decompressions. It is not necessary though since the FINN LIGHT torch can light much longer above average.

In clearer Austrian lakes I switch off the torch on the way back to the surface according to the conditions, however not before longer decompression stops at about 10-20 m deep.

While cave diving and at night I logically light my way even on the surface before entering the water and also after I surface. I never switch the light off in the water. The only exceptions are when I emerge in seeps during daylight – in France etc., where I sometimes switch the main torch off before I surface.

I do not dive in ocean much. However, due to better light there is in sea waters in general the user can switch the light on/off as deep as roughly -40 msw, if the torch is properly maintained. However, almost nobody makes long decompression stops in such depths. So it is just a theoretical possibility to control something that doesn’t need to be controlled.

The torch can easily withstand depths over -150 msw. It is very lightweight and space saving. Very sharp luminous angle helps with clear communication among divers. Another plus for long dives is the long runtime that is really above standard. In addition to that, high quality materials have been used, the make is robust and the Goodman handle neatly accommodates one’s hand. These are the specs and features that I’m interested in the most when it comes down to diving torches.
