Same here. Hunting eels does not require particular skill as you point out correctly.
It's quite an easy fish to spot and the easiest target to shoot. Retrieving them is the only hard part, but retrieving itself is more an annoyment than a really difficult task, most of the times.
We shoot them to eat (mediterranean countries have a tradition for cooking eels in many fashions) or in competitions, when and if comp rules enlist them as valid catch for tournament score. But competitive spearos themselves tend to leave eels there where they are, as it takes much time to kill and retrieve.
I find it also fun to find them, as you have to scan the bottom very carefully and, in the continuous up and down quest, you always notice something interesting to see. It's what we locally call the "stitching machine" type of hunting.
