I got this idea while reading the "2 way radio binocular"
and wondered if you could add a flashing laser pointer on
pair of binoculars so that when a lifeguard saw a
trouble, they could press a button on the binoculars
would turn on the laser pointer. Then activate
mortar which would fire a laser guided Nerf-type
device to the swimmer.
Alternately, you could create a large Nerf bazooka, which
would deliver the device with lower tech. The downside
this is the level of wind usually found at a beach leading
poor accuracy with a low mass projectile. This could be
improved a little by using a projectile that inflates in
contact with water, so you could use something small
and reasonably light that would still be usefull to the
2 way radio binocular idea

||Wind compensation is a known science in military
||Yes, I saw that, in fact it is the reason I picked the category, but it is mostly unrelated. Your idea
throws the lifeguard, mine more realistically
throws a Nerf like projectile.
||I agree that wind compensation is a known
science, but I'd disagree that it is known for this
light a projectile, this long a flight time and those
wind conditions, as the wind conditions could
change radically during the flight, so without some
active correction your accuracy would never be
||Rather than a Nerf, this should fire a solid projectile like an airbag that explosively inflates in the air over its target.
||...and dazes the unsuspecting swimmer.
||Might take his mind of the whole drowning bummer.
||Once the narcosis takes hold it's really peaceful... not quite as peaceful as freezing of course, but peaceful.
||Lifeguard trebuchet- //...gets something like a paintball gun, but it fires different coloured polystyrene spheres, with a hole through them. Then, at the cry for help, the beach people fire the spheres towards the drownee, who can then collect the spheres, thread them on the piece of string and make themselves a life belt//
||Same but different, but your idea is more practicable, I'm presuming it could be mocked up to look like an RPG for scaring the crap out of the drownee purposes?
