PTT-100 9.5 gram Solar PTT

Buoyed by the success of our 12g solar PTT, we redoubled our efforts to further miniaturize the PTT. Only a year after introducing the 12g model, in December of 2005 we introduced the 9.5g solar PTT. It was finally possible to satellite track birds in the 300g range.

Like its larger predecessor, the 9.5g solar PTT is equipped with an internal rechargeable battery that is charged by the solar array under the control of the internal microprocessor. The capacity of the battery, when fully charged, is sufficient to allow transmissions through the night.

This tiny PTT has made it possible to satellite track many more species of birds, including Hen Harrier, Marbled Godwit, Whimbrel, Montagu's Harrier, Hobby, and Skua.
