Rc Tech Trading offers this 8-pack of repellent stakes featuring a vibration motor that is decoupled from the main housing. This design is intended to reduce "noise leak" above ground, keeping the device quieter for humans while focusing the vibration into the earth. The units use a combination of an ABS head and a polypropylene stake, designed for deployment in soft, aerated turf.
The power system uses a 2V/45MA polycrystalline solar panel. Because the battery is a 600mAh Ni-MH cell, it can be sensitive to "memory effect" if it consistently receives only partial charges in the shade. For a full 24-hour operation cycle, the stakes should be placed in areas that receive full sunlight. The 400Hz to 1000Hz frequency is most effective in loamy soil types and may be deadened by heavy sand.
During assembly, ensuring the silicone gasket is correctly aligned will help protect the internal electronics from ground moisture. The bulk 8-pack provides sufficient density for about a 1/4 acre property. Like all plastic garden tools, these stakes are most durable when installed in pre-drilled holes to avoid mechanical stress on the spike during setup.
Summary: An 8-unit set designed for quiet operation and efficient solar harvesting in standard residential lawns with loamy soil.
For properties with particularly tough or hard-packed soil, a version with an aluminum shaft may provide more structural durability during installation.
