Hi Guys. Here's a few answers to the latest queries. The housing makes the tracking tag "water resistant". We say that because we've only tested it down to around 4-5 feet. At that depth no water came inside the housing. We don't know how deep we could go before water starter seeping in though, so we can't say "water proof". During the time that we were designing and testing, we glued a lot of stuff to the bottom of discs. In every case we saw that every aspect of the flight characteristics were affected in some way. And the crazy thing was that it wasn't consistent. The additional weight and shape of the tag affected a Sidewinder differently than it did a Wraith, TeeBird, etc. Not to mention that keeping the tag attached was super difficult when the disc hits any solid surface. The bottom line is that adding anything to a disc will affect it's flight, regardless of the size and shape. So, even though we tried to stay away from making our own line of discs, it was the only way to solve all of the issues we were experiencing. Our design counteracts the additional weight and shape of the tracking tag. Additionally, our modular design allows you to change out what's inside the housing. We have some other ideas for that so stay tuned. The name TOBU is the Japanese word for "To Fly". (it has meaning and we thought it was catchy) And the name Ping is related to the ping that you get when tracking something on a radar. Finally, the electronics in the disc are made in China. As always, thanks again for the suggestions, opinions, and interest in what we're doing. If you like it, please consider donating to our Kickstarter campaign.
Thanks!
