I believe that studies (which I cannot find citations for now) determined that this device makes the sutation worse, as it scatters metalic debris over a wider area, and that human mine clearance teams have to work an order of magnitude harder, cleaning up tiny bits of shrapnel. Before an area can be marked clear, it has to be devoid of all unidentified metalic shards, and of course, all mines of other materials. As a result, it was the determination of more than one agency that this device makes things worse. With that said, props to the designer for working on a solution to a difficult problem, but perhaps more domain knowledge would have lead him to a more suitable solution
