According to the manufacturer, the range is approximately 100 feet or about 30 Meters.
A projectile could be designed for the tail to separate on impact.
If you shoot along a specific bearing and follow that line, I think the projectile will not deviate more than 30 metres left of right so you should be able to find it. Then again on an empty beach you could probably see it at that distance.
I think the ultimate solution is a device that beams its location in real time... something like this: http://www.ebay.com/itm/Vehicle-Car-Tra ... 19db7af97b
The problem is that it's pretty wide, the projectile would need to be around 1.5 inches diameter, so it would need a big bore launcher.
