About the other organization that will be searching this weekend, Team Watters Sonar Search & Recovery:
"Nonprofit's assistance was crucial to finding Toni Anderson's car"
"[Dennis Watters] says Anderson’s car was difficult to spot in the deep, fast moving waters of the Missouri. However, once his sonar pinged it he knew he had a car."

"Chrissy Williams found dead"
"Jackson said the family hired Team Watters Sonar Search & Recovery, Inc. from Moro in the Metro East area. The not-for-profit volunteer organization specializes in assisting law enforcement in recovery of remains, vehicles and items.
Jackson said Team Watters found the SUV’s location in the water within 20 minutes of beginning their search."

I'm referencing these particular cases just because I followed all of them here on Websleuths, but they have had many other successes. They often work in conjunction with TES.
Also, -though this may sound kind of weird- kudos to the Hunt County Sheriff's Office for agreeing to have them come in. Sometimes I get frustrated -as a layperson- with LE when they refuse to have outside organizations help despite families' pleas.
I have a lot of confidence in both of these groups (Tim Miller ... what an angel), and if they do not find PaPaw -gosh, I hope they do ...- at the end of the search, then I feel pretty certain he is not in whatever area they are working in.
