Protect Koi From Predators
 

Jumpo Trainers can be placed along approach areas or scattered about to scare raccoons and herons.

Use the double-bungee sets with expanded triggers. Use a lot of Jumpos! Animals in search of food are very hard to deter!

One additional trick to the double-bungee set up is to tie empty aluminum cans or dixie cups to the ends of the Jumpo's wings. When the Jumpo fires, an extreme commotion is made by the clashing cans or cups.
