Y-kiki Divers


Thanks Y-kiki divers for again sponsoring our Midwest Cave Diving workshop. We had some great diving, fascinating speakers (including Bill Harrison on yoga for cave diving), an opportunity to check out a dry cave, and of course raffles. Special thanks for donating the sweet Dive Rite reel I won. I'll put it to good use!
I’m a Rescue Diver! thank you Cindy Schrader and Scotty Battles for your excellent instruction. I stayed in a great Airbnb in Mermet.
She wants to know if she can come to scuba class, says it is boring staying at home while her people are at class.

On Saturday, July 15th, Y-kiki Divers celebrated our 5th annual PADI Women's Dive Day at Mermet Springs! We had 20 divers join us for the event and everyone really enjoyed our scavenger hunt throughout the quarry.

The day started out pretty hot, but quickly cooled down after a few short rainstorm showers. Water temps in the shallows was 75-degrees Fahrenheit, with bottom temperatures near the nose of the 727 sitting around 55-degrees Fahrenheit. The showers didn't disturb viz and everyone enjoyed around 15-20 ft of visibility all day.

Our thanks to Barry & Shaun at the Snack Shack for lunch. Big shout out of thanks to our sponsors for helping make this event happen: ScubaPro, TUSA, Innovative Scuba Concepts, Shearwater, Mermet Springs, and, of course, PADI.

Congratulations to our big prize winners this year!

We had an amazing weekend with a lot of divers this weekend at the pool and at the quarry!

It was definitely a HUGE weekend!! We certified 23 Open Water Scuba Divers (including a bunch of divers from our Kirkwood Middle School's Pursuit Week finishing up their open water dives!), 7 Advanced Open Water Divers, and a handful of specialty divers. We also had 4 students complete their Rescue Diver certifications as a family!

At the City of Manchester, we introduced 14 people to the magic of scuba diving in their Discover Scuba Diving experience. We hope to see you get certified in class soon!

We also had 5 Open Water students complete their confined water dives in the pool this weekend. It was great to see the Master Seals working on their AquaMission Wreck Diver class in the pool this weekend too. There were even 16 scouts working on their Boy Scout Swim Test, Swimming Merit Badge, and Snorkeling Award at the pool.

Check out our pictures from our fun weekend!


We just got word that we lost long-time friend, Steve Wobbe yesterday. He was a big part of Y-kiki Divers… well before Ken and I bought the shop in 2005. He stayed on with us and was part of the initial cross over to PADI.

He taught countless students to scuba dive. And I know our friend Jane Palmer credits Steve for getting her past her fears and helping her become a certified scuba diver.

He was a calm, generous and patient individual and he’s been very much missed. RIP Stephen G Wobbe 10/23/1950 to 7/10/2023. We remember you fondly. Our sincere condolences to Priscilla Wobbe and his family. ~Valerie & Ken Elliott & your Y-kiki Family
