Robohips and I took a trip up to the White Star quarry today near Toledo.... The viz was good, not great, about 25 to 30 feet. I had two great dives in the 51 degree water using the Hydroglove and my blue label Voit Lung. But wait...there is more..... My Tekna was recently serviced by Robohips and I must say it worked flawlessly. On the second dive I took it to the depth of 70 plus feet and ran it full speed for 44 or more minutes without stopping. Robohips AKA Roger never ceases to amaze me with his abilities to repair these vintage tekns DPV scooters. Thanks again Roger and thanks for diving with me today.
