Trust me guys these go threads are the best compared to all other sand trax like MAXTRAX MKII etc because I have personally used maxtrax and some others. However, the main difference of the Go-Thread is its lightweight design, it can be folded, and also the drawbar does not rely on the teeth of the Traks. becoz maxtrax goes bald after being used continuously for over 10 times for serious recovery. but Go Caterpillars are the best.
