Why should one carry bulky device to attract a sandworm?
It is much easier to carry several (very compact and very basic, simple) shield generators.
Set one and wait for the sandworm.
It is noted in Children of Dune (1976) that the Fremen have developed a small shield generator known as a "pseudo-shield" to attract and madden a worm, for use as an ersatz bomb:
Seems that the only problem is that a sandworm attracted by that shield would be hard to control.
Is it so?
