About fluorescence

To see this underwater, you'll need a light with an "excitation filter" attached AND a "barrier filter" on your mask and camera system. What you'll generally see is a glow emitted from a variety of corals and animals, mostly in greens, blues, and reds. You may find two of the same type of corals—one which fluoresces, and one which doesn't. Dive your favorite spots in a different light and see what you've been missing!

Fluorescence is technically the photon emitted as an electron relaxes from its excited state to its ground state. In layman's terms, it's the glowing you are familiar with in glow sticks, jellyfish, and forensics. A variety of organisms and materials above and below water exhibit fluorescence—often with the introduction of a particular wavelength of light.

Fluorescence photography may be captured during the day by experimenting with using a very powerful, filtered light source and under-exposing the ambient light.

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.

Update 18/12/2020: There are some production delays at present that may increase wait times on items like housings. We apologise for the inconvenience. If there are any delays with your order, we will communicate this immediately.

How do you ship my orders?

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.
