Hey lol I got this tiny sub at walmart and it ranges farther than my walmart dallas sub! Actually we have two so me and my son can run them together. It went all the way to the bottom of the four foot pool with no problem, my dallas sub starts to loose signal at the bottom but im doing some mods to it. Amazing how this small sub does as well or better because it is tiny, it has lights too so we will try them tonight.
