> Indiscriminate in the sense that bombs have an area of effect beyond the person carrying them

AFAICT the stock pager models are ~95 grams, and people are suggesting 3-5g of added explosives. If they used RDX, then 3g would be ~5.5 cubic centimeters, which seems like rather a lot to try to squish into a small pager unless the design also replaced the standard battery with a smaller one to make room.

In contrast, a M67 fragmentation grenade uses ~156 grams of explosives.

Basically I'm saying it sounds like the bombs are small enough that it's not quite fair to call them "indiscriminate", especially if the trigger logic involves a Hezbollah radio network that nobody else would be using.
