Alright folks, thought I'd mention some of the applications of this device, just to get you thinkin' as to what it can do for you.
Yes, you can put packages together, that's the most obvious application.
Requeening a really big, mean colony, getting the numbers down to make it easier to find the queen, this could really come in handy on AHBs.
Splits, spring and pre-fall as well as congested hives
One of the really nice things about this device is that you aren't disturbing your other hives in the yard. When we put together packages last year using a large funnel, the bees were everywhere, got a lil crazy have to say.
