I have none, just a winch, shovel, straps, shackles, snatch block, and mud tires. Been in powdery sand plenty never needed a track just air down to atleast half and keep your momentum without spinning the tires. Ie feather the throttle don't step on it trying to get out like you do in mud, on most beaches the sand has no bottom as far as you dig is as far as you'll go, sand in desert areas normally has rock at some point digging in but don't count on it in soft stuff solid ground may be feet or yards beneath you.
If your stuck in sand the very first thing to try is rock your vehicle back and forth compacting the sand works better in wet beach sand than desert sand.
