"‘PowerRay’ is an undeniably cool new gadget for the relatively untouched hobby
fishing market.:
Yeah, no one makes
fishing gadgets...
Honestly, that might be a good
learning tool but any halfway decent fisherman knows how to interpret what they see on a
fish finder.
I understand that they want to try and market it to every segment they can, but this looks like a solution in search of a problem when it comes to fishing.
However, it could be useful for scouting reef openings, checking your
anchor if you're the type who does not like going in the
water. I suspect the range might be a bit iffy for some applications.
