The rating of this set depends on what you expect, as in most cases. From the pictures I saw, I expected an average-sized truck or smaller, nothing too fancy. Well, all said: I was proven wrong!

Box/Instructions

Nothing special. Standard box, one booklet, that's enough. Once again, the instructions are VEEERY detailed, so the booklet comes out quite long for a set this size...

Parts

Standard LEGO parts for a vehicle. Additionally, some TECHNIC parts for the drill arm. What I liked is the abundance of gear for the minifigures in such a small set! You get a jackhammer, a walkie-talkie, a ground detector-thing and a lava rock with a carrying device (?).

Minifigures

The set comes with two minifigures: a female scientist with a breathing apparatus and a male bearded driver for the ATV. The number of figures is good for a set this size, some older sets only have one minifig.

The build

Easy, straightforward build, starting with the chassis and finishing with the drill arm and the tires. During the build you realize, this is going to be one really tough tracker!!

The completed model

Even though it has nothing too special on it, it looks very cool! Personally, I like the green design, it's something different than just the normal white and grey and red from standard CITY-sets. The bulky tires support the overall strong and sturdy impression of the set. After the build was finished, it came out much bigger than I expected!!
I also liked how you can switch between the drill and the hook to attach to the arm. The other part can be attached to the lower back of the truck, so everything stays together.

Overall opinion

A nice set for a good price (I got it for 15€). What makes it that good is the potential in playability! You can combine it nicely with other trucks and it fits really good into the whole Explorers-Subtheme (I call it that way). I can't find anything negative to say about it, maybe only the original price of 20€, which is a little too high IMO. Would be a nice present for all lovers of LEGO trucks!
