Ludlum 43-110. Check it out at

It's a windowless gas proportional detector.  It works fine with
limitations: slow response, non-planar surfaces and wind can challenge
even the most patient surveyor.  In all fairness, the probe was taken on
a "field trip" recently and successfully identified tritium
contamination that originated with some damaged exit signs (multi-Curie
sources).
