UWE and Ocean Quest are excited to announce that Greg and Ken has completed the Hollis Explorer Course this past week.  The Hollis Explorer Course is an excellent and challenging course to complete.  Though we have many years of experience and have in-depth knowledge of diving, there is always more to learn.  The Hollis Explorer is an eSCR Hybrid Rebreather that is an easy and fast setup, with a 10 or 15 minute automated pre-dive sequence to do in order to get into the water.

I found the setup of the Hollis Explorer pretty easy to do.  The back mounted counter lungs are easy to install and pretty difficult to confuse.  There is really only one way that they will install.  I was diving the Hollis Explorer with 40 % NITROX in my cylinder which allowed me a 100 foot MOD for my dives.  With the automated DCP engaged this allowed me to keep a high PO2 which allowed me a longer bottom time while still remaining within the No Decompression Limit. I found it challenging with the solenoid firing at depth to remain at a constant depth without venting the loop through my my mask.  This will take more practice to make it a natural maneuver without thinking through how to keep level.  But with everything practice makes perfect.

I want to address the comments I have read on Scuba Boards about the scrubber life.  There is a thread that has been going on for sometime

reference the scrubber life on the Hollis Explorer not operating as advertised and I have to disagree totally.  As it was explained to me, the scrubber indicator on the handset will indicate 90 minutes at the beginning the dive but if you pay close enough attention the the handset you will see that it does not count down based on minutes of the dive.  For example my last dive was 87 minutes in length and when I exited the water it indicated I still had 74 minutes of scrubber life, which would allow me more then enough time for a second dive.   I am totally sold on the Hollis Explorer, this is a fantastic eSCR rebreather that is well made, and easy to set up predive and then dive!  We took the training through Bill Coltart who is a very knowledgeable and professional instructor!!  Bill thank you for the Hollis Explorer Course, I look forward to diving with you again soon!!
