But where are your small ones?

It seems that just the other day a 200 gram wildlife GPS collar was considered really light.  I was at a wildlife conference last month, a 50 gram GPS collar was on display on our table.  Someone picked it up, looked at me with disappointment and said, “Where are your small ones?” I took that kind of personally.  But as Tom Hayden said, “It’s business Sonny, not personal.”  Ok, so I got over it.

Friday we built our smallest GPS unit ever, 6.7 grams. We built this for a bat, it slips onto a Holohil VHF collar using the passageway at the bottom.  Seems that we have come a long way since 200 grams was the lightest GPS collar for wildlife.
