CYLINDERS
I have to retest my old SCUBA Aralù, is there any problem?

The Aralù self contained breathing apparatus (SCUBA) were produced by Technisub until 1991 using aluminium alloy (AA6351) cylinders manufactured by Luxfer Gas Cylinders, a British company. It has been discovered that, after years of intensive use in certain conditions, a limited number of these cylinders may exhibit a metallurgical phenomenon known as “sustained-load cracking” in neck and shoulder area of the cylinder. Sustained-load cracks grow extremely slowly, but, if undetected, they could eventually cause a cylinder to leak or, on rare occasions, to rupture. However, these cracks are usually detected before they become a problem during normal visual inspections by a qualified inspector. It is important to note that, to date, there have been no ruptures of any of these cylinders in Italy. Nonetheless, TECHNISUB and LUXFER invites all owners of Aralù cylinders, made from AA6351 alloy, in Italy, to send them to LUXFER Italian Service for a free inspection. We will test the cylinders with a special device, designed in the USA and based on eddy-current phenomenon, that can detect microscopic sustained-load cracks long before there is any danger of a leak or rupture. If you wish to take advantage of this free inspection, please send your cylinder(s) to:

Luxfer Gas Cylinders will bear the cost of the first test, while the customer will pay for transportation and any other desired services, such as dismantling and refitting of valves, two-yearly retest (if appropriate) and refurbishment. If your cylinder passes free test, it will be returned to you for continued use. If your cylinder fails the test, it will be destroyed and we will offer to replace it with a new cylinder at a special price. This eddy-current test and visual inspection should be repeated every two years, preferably at the same time as the two-yearly retesting of cylinders required by the Italian regulations. All subsequent eddy-current tests and other required services (including retest) payments will be the Customer’s responsibility. If the cylinder fails the test, it will be destroyed and the offer to replace it with a new cylinder at a special price will be upholded.

MASKS
With the SPHERA, can I use traditional methods to avoid inside fogging up?

No, different systems from the special anti-fog liquid, code 542.210, would cause irreversible damage to the inside of the lens.

Are there any masks for people who wear glasses?

Yes, our LOOK mask can be easily transformed into optical masks. In fact, optical prescription lenses can replace the original lens in a few minutes. The optical lenses available are: negative symmetrical lenses (from -1.00 to -10.00 with steps of 0.50); positive lenses (from +1.50 to +3.00 with steps of 0.50).

My face is quite small, are there masks that are suitable for me?

In our range, the Ventura Midi mask is designed for the small faces of women and boys and girls.

SNORKELS
The mouthpiece I use makes my jaw stiff; are there any solutions to this?

There are snorkels, such as our Air and Flexus, which come with an orthodontic mouthpiece that has been specifically studied to reduce strain on the jaw or with the Midi mouthpiece that is suitable for smaller dental arches.

Why do they have that cap?

To reduce the possibility of water entering during snorkeling as much as possible and to act as a visual marker thanks to its unusually intense red color.

TORCHES
I have a VEGA 2; can it be made rechargeable?

It's not a good idea. Altering a product almost always means altering the original performance set by the manufacturer. Moreover, the change leads to the Guarantee lapsing with important consequences not only on the technical level, but also from the civil liability perspective.

Can VEGA 100 be used as a light for videosub filming?

Of course. We have the Flou Vega 100 Video Kit, code 562.740, which provides a very white, mellow and evenly distributed light beam. I have a rechargeable torch.

Do I have to recharge it continuously?

As indicated in the instruction booklet, it is a good idea during long periods of non-use to let it run down and then recharge the bulb completely once a month.

Are your rechargeable batteries subject to the memory effect?

No. On the rechargeable torches we sell, we use batteries that do not have this effect, used with the Technisub chargers that come with them.

Why can't I find the bulbs for your torches in electrical stores?

We use bulbs manufactured on Technisub specifications and available exclusively through authorized Technisub dealers. Note: the modification or use of unoriginal parts alters the original performance set and leads to the lapse of all guarantees.

KNIVES
Do BC knives exist?

hanks to the standard accessories. It is important to note that all the BC knives in our range come with a special holster to place and attach the MINI ZAK. It can also be carried on the belt using two loops inserted in the sheath.

Does the knife need maintenance?

Yes, it must be carefully rinsed with fresh water after diving, then left to dry outside the sheath. Every now and then the surface area should be protectively coated with a thin layer of silicone grease, code 549.150.
