Despite me saying I don't do Monday Morning Engineering jobs, like an idiot I bought one anyway cause I hate looking for discs. I guess I had to learn the lesson once again. So you're not alone, I can't get mine to detect much past 3 feet. If I have a disc in one hand and reader in another, it will stop shortly before my hands are fully spread out - maybe max 4-5' - and my ape index is nothing to brag about. Keep in mind, when looking for discs, this may not actually start chirping until 2 feet or less, 4-5' is just max distance I got so far.
In fact, the entire comment section on their kickstarter is full of disappointed users:
WARNING: Totally layman understanding ahead.
I got SLIGHTLY better results if I put a second sticker on that thin inside rim (trim the sticker down to the exact antenna seen on the bottom side) and that's because at 90 degrees these stickers are nearly invisible to the reader - so a second stick at perpendicular angles makes sense. HOWEVER, testing with more stickers (on the rim or elsewhere) made results worse -- possibly because each sticker is catching part of the power of the signal but now each one having now less energy to send a pulse back.
They also are giving now tips after the fact, like pointing the pigeon logo of the finder towards the disc, which they do in the video but don't articulate. However, my own testing indicates it makes little difference what side of the puck is pointed at the disc, the bottom is as good as the top, just not the sides.
The PR team on this whole venture is a disaster unto itself with bad or no communication. They are using corporate speak to address this issue:
And offer kickstarter early supporters a chance to buy an upgrade at steep discount, whenever those came out. Question is, who wants to throw more money at something they should have gotten in the first place?
ALL SPECULATION AHEAD:
Anyway, given their initial videos showed it working at 20 feet, I can only conclude it was EITHER a scam, but I have doubts there... there is another possibility as I have personal experience with products out of china. It may have been the prototype they either made themselves or were given by the factory was much more powerful and the factory did a bait and switch on the production run with a less powerful radar or whatever it is called. Afterall, handheld RFID reader are expensive, we're talking often $1500 range.
So there is a chance this was an earnest project that has gone wrong, maybe not hiring an expert or having sufficient Quality Control, or whatever, and rather than being stuck with a bunch of worthless pucks, the financial damage get distributed to us.
This pro-locate demo right here shows the exact basic thing working YEARS AGO, but that's a $1250ish Zebra RFID reader with a smartphone on top:
It could also be something else, I'm no expert on this and don't want to be. I just know I wish I bought extra discs instead.
Get yourself a decent retriever, buy discs in bright colors, anything else will have better bang for the buck right now. I wish this worked, I really did. But it doesn't.
I wish you luck, but Kickstarter was pretty clear that the money is going towards supporting the project and even getting the reward is not guaranteed.
I would say save all the emails, download the videos from youtube (google it) as evidence, and make screenshots of anything relevant including FB posts and kickstarter comments since all that can disappear without notice.
Btw, "David Greenberg" on Kickstarter seems to be "David Benjamin" on Facebook. Which name is real, is either? Idk. He was posting the Homing Pigeon for months in the Tranquility Trails (Swedesboro New Jersey) Facebook group, going back to at least May, before it came out. I found it via a FB link either on their website or Kickstarter but has since been scrubbed. I also found some FB posts scrubbed.

You saved yourself a good chunk of change. This thing is a POS. Good luck finding your disc.
