The Battery Powered 45g PTT is our lightest battery-powered backpack-style PTT. It is designed with a low-height, sleek housing. This model is useful for species weighing >1.5 kg, especially those that preen feathers over backpack attachments or that occupy habitats or latitudes with limited sunshine.
