Description

Prospecting on the seabed

The Aquazone world revolves around divers, submarines and glowing crystals in the deep sea. The detector fits right in: a small device the Hydronauts use to search for the precious resource. At 106 pieces the set is small but full of detail, and it can be built as a standalone scene or slotted into a larger underwater landscape together with other sets from the line. It is a small but typical example of the line.

Trans-green and yellow

Black, yellow and light grey form the foundation, and transparent green is added to suggest crystals and water. These transparent parts are the visual trademark of the line and keep its sets attractive to collectors today. Of the 106 pieces, 54 are different types, so nearly every second piece is a different element. That is a lot of variety, and it opens up plenty of room for detail and special shapes in other models you may build.

In play

The single minifigure is a diver or researcher who operates the detector. The set therefore suits small stories about discoveries on the sea floor, and combines well with a submarine or a base. If you are looking for a used copy, inspect the transparent parts carefully, because they can show scratches or discolouration, which is not unusual with older sets and can spoil the overall impression of the model. Photos of the instructions help judge the original condition.

Parts list and collection

Every part with its colour and quantity is listed further down this page. It helps with checking a set and with buying missing pieces precisely. If you already have bricks at home, try the “What can I build?” tool to see which models your stock allows. The transparent green parts in particular are in demand for other builds, as they work as crystals, lights or water effects and stand out quickly there. That is worth doing before you buy or resell a used set.
