“It has two harpoons on the front as weapons, as well as two propellers. It also has two propellers in the back, even though is has wheels. It has two claws for grabbing crystals or enemies. The set is almost entirely yellow, with some black mixed in. At the back are two... More diving flippers. The vehicle is piloted by an Aquanaut. The set also includes a bush of seaweed.”

Lego Maniacs' Guide
“This is one unique sub design. It's almost like a submarine/truck in the sense that it has wheels to move along the ocean floor. One Aquanaut pilots the sub, and he is equipped with flippers and knives. There are two grabber arms to gather crystals, and two harpoons for... More defense. Overall, this is a nice sub, and comes with a rare element, the 2x2x2 spring piece (also featured on the Blacktron II Spectral Starguider). It also includes seaweed and an ocean floor plate to move the sub on.”

About Aquazone Aquanauts

Aquanauts was the first subtheme in the Aquazone theme from 1995 to 1996. The story consisted of the Aquanaut miners, a group of miners based at the Neptune Discovery Lab, fighting against the villainous Aquasharks and their leader Thresher for control of the crystal mines. The first generation of sets consisted of a yellow base color to the subs which gave the Aquanauts a more realistic appearance to real submarines.

Aquanauts consists of 8 sets that ran from 1995 to 1996. As of today, 6195 Neptune Discovery Lab is the most valuable Aquanauts set with an estimated new/factory sealed value of $602.
Summary
Aquazone Aquanauts Crystal Crawler set 6145 was released in April 1996, retailing for $12, but has since been retired. New, unopened Crystal Crawler sets are valued at $103, while used sets can be found for $24.
