This mod adds in an item called the Ultra Miner, which, if used by clicking on a block with it, will clear out all the (sand)stone, sand, gravel and dirt in a large area in front of you. It's kinda expensive to make (2 dia picks and 7 gun powder), but it pays off itself, because, if used around y = 10, you'll easily find 6 diamonds in the cleared out area.

I used to develop mods, I started modding before modpe and blocklauncher was even a thing. I have retired from the forums. I will no longer be active as of February 18 2015. I will miss my forum friends :(.
