I just ordered two brand-new Spot Hoggs last week...

the Hogg-It for 3d will have four pins in .10

The Hunter Hogg-It has four pins wit the top one being .19, and the last three .10.

I figure the top one in .19 will allow it to gather light more efficiently and I'll be able to see it better at dusk, and I'll have a pin I can use as darkness closes in around me.
