Nauticam is pleased to announce an exceptionally comprehensive vacuum system that allows the underwater photographer to confirm watertight integrity before entering the water. This system provides additional peace of mind with expensive camera equipment and should mean fewer lost dives due to minor equipment issues. The system is comprised of two parts, a one way vacuum valve and an electronic monitoring circuit.

Note: This electronic system is pre-installed in all Nauticam housings post-2013.

If replacing the system installed in your existing housing, please check whether your housing uses a CR2450 battery Vacuum Detection system or a CR2032 and order the same one.

Monitoring Circuit

The electronic monitoring circuit is compactly integrated into the housing’s leak detector, where it constantly measures the vacuum level and reports its status via a multi-color LED easily visible on the rear of the housing. This sophisticated circuit has an advanced temperature compensation capability, so changes in ambient temperature or changes in internal temperature won’t cause a false positive.

Starting with NA-70D for Canon 70D, all new Nauticam DSLR and Mirrorless Interchangeable Lens Camera housing models will ship with the electronic monitoring circuit installed as standard equipment. Vacuum valves are sold as optional equipment, allowing the user to customize the housing accessory configuration as needed. Understanding the LED color codes is very easy. At ambient pressure, the LED slowly blinks blue. When a solid vacuum is achieved, the LED changes to a solid green, indicating system integrity. If the vacuum starts to degrade, the LED begins to flash yellow, and if water intrusion is detected, the LED flashes red, and the audible alarm is sounded.

Retrofits for existing housings are available starting November 4, 2013.

Vacuum Valve

The second component of this system is a one way vacuum valve, which is available in several styles to support various housing configurations. These Vacuum Valves contain an integrated vacuum release, and a redundant waterproof cap. No tools are required to open the housing after creating a vacuum, as the vacuum is released with a simple knurled nut.

The basic valve uses a hand pump to create the vacuum, but a more advanced Dual Activation vacuum valve is also available. The Dual Activation Valve accepts a BCD Low Pressure Inflator Hose quick disconnect, and uses tank pressure to create a Venturi effect that pulls the vacuum. This is recommended for housings like Nauticam’s DCES for RED EPIC and SCARLET where the internal volume of the housing makes using a hand pump impractical.

“Offset” Extension Valves are used when a housing has a single accessory hole, but requires both a Vacuum Valve and electrical bulkhead to be installed in the same location. This will enable most housings to be able to utilize this valuable tool.

All vacuum valves also include a hand pump and spanner tool for installing valves.

The Bottom Line

This new system is the most advanced integrity check system available today, and the only one with integrated leak detection and temperature compensation. With it’s intuitive multi-colored LED status codes, the underwater photographer can now be assured with a simple glance that the watertight integrity of the housing is secure.

April/May 2022 Delays:

If you need things urgently please contact us and check ETA on the items you require.

How long will it take for my order to arrive after I make payment?

That depends on where you live and whether we have an item in stock or not. While we do have many items in stock, we don't carry everything. If you need an item in a hurry, it's a good idea to contact us and find out if your item is in stock.

If we have it in stock, we can usually send it out as soon as we receive payment, or you can pick it up. If an item is not in stock, we'll need to order it from our suppliers, which means it can take 1-2 weeks to arrive at your door (usually closer to a week).

Sometimes delivery can take longer, if our manufacturers are out of stock, for example, but this is unusual - we let customers know as soon as possible if something like this happens.

How do you ship my orders?

We use New Zealand Post and CourierPost to ship orders. Our default is courier, though you may organise an alternative with us by contacting us directly. CourierPost aims for next day delivery nationwide between major towns and cities in the North Island. South Island delivery can take two days.

When you buy something from us, the price is literally exactly what it says on the tin.

If you buy something from an overseas supplier, that is most definitely not the case. While the product might seem like a great deal on screen, it's important to understand customs and import costs.

In addition to the ticket price on an overseas purchase, whatever the exchange rate is on the day (this can fluctuate wildly - trust us, we know), there are also tariffs, GST and border processing fees. This can easily add upwards of 25% to the ticket price. Items costing over NZ$1000 also incur import entry transaction fees.

In addition to these extra costs, Customs clearance can also cause delays. Sea Tech has been importing for years - we've got this down to a fine art, and we've built relationships with customs that help our items clear quickly.

By buying from Sea Tech, you avoid all the headaches, delays and extra costs. We handle all this stuff for you, so you don't even have to think about it.

These Nauticam housings are non-returnable, non-refundable, non-cancellable, and may be subject to extended lead times as they are manufactured on demand. We always do our best to meet trip deadlines so please advise us if you have a trip coming up!
