1. Who knows what you’re blasting? Plus, you may be introducing counterproductive “noise” (in much the same way as our artificial lights screw up the star maps of moths and other insects). In the former case, numbers at least appear to be so few that one might not want to do this.

2. Then again, sometimes you do get a response. I’ve read more than one TBRC account that describes what certainly seems to have been a response to a call blast.

I’ve imitated ravens’ calls on numerous occasions. I think I’m pretty good; but I also think I’m no raven, and that they can hear that. Almost every time I do it, though, I get what clearly seems to be a response; the bird (frequently plural) not only comes back vocally, and repeatedly, but intently circles my position, invariably coming closer to me, almost undoubtedly to identify the clown because not too many of those people critters do this.

Until clear negative ramifications of doing this can be identified, though, not sure I can be against it (I mean, after all, I’m doing it too, right?)

The call blasts we use have a signature “added” sound that ensures that other humans hearing it will know it’s a recording vs. live. I have no fear in my remote area that “other” bigfooters are operating/call blasting without my knowledge.

I think what should be emphasized is that researchers are free to pick and choose their own methods. What works for them may not work for someone else. If you think something new will work, you should try it. We have tried children laughing and cooking smells (along with many, many other things). Call blasting has been one of the few consistent methods that we feel produces results.

Re: “sasquatch” comment above – “…and can’t recall if I’ve EVER read even one where people were out call blasting and a Sasquatch came into sight” – there are several reports of distant responding howls getting closer and closer and then stopping – so how are we to know if other curious Bigfoots respond silently, then lurk, just out of view, watching?

Creatures have been startled from hiding when fisherfolk or families or partyers have unexpectedly stepped into the woods to relieve themselves or gather firewood, and we know Bigfoots can move around soundlessly, so it doesn’t invalidate call-blasting.

I would scan the location’s periphery with Gen 3 Nite Vision, Thermal and audio gear, call blast, continue scanning, wait until all the echoes die away, scan and blast again, wait longer, scan and blast etc… wait, what’s that heat blob moving at the edge of the woods? It’s getting larger – IT’S COMING THIS WAY!

Quick! Where’s my camcorder?
