Ray; I was given one to try out ....? Naah. Didn't like it. Very pricey, to start with, as I remember. No way I'd be buying a dozen of them
Best place to use them, round here, would be shoved into an existent pipe along a stream. But, those pipes, which the creatures are used to, are plastic. Overall, I found the trap a bit 'steely', they being after all 100% steel.
Setting wasn't the finest, I seem to recall. Maybe the power of the spring, working against the delicacy of set I'd have preferred?
Dunno. All things considered? I just found myself thinking: " What does this expensive, steel pipe bring to the table, when compared to a bunch of home made snares? "
Last time I remember seeing it? It was rotting out beneath my hedge. Slung there. Since slung away.
