Hollis Explorer Course

UWE has completed the Hollis Explorer Course that was taught by Bill Coltart from Pacific Pro Divers out of Courtenay.  The course was very well run and we were able to put some of the video’s together, we hope you enjoy.  I am hoping to be up and teaching the Hollis Explorer Course by late summer.  I am currently spending my days diving this amazing machine that is easy to set up and predive.

Looking forward to seeing you out there diving the Hollis Explorer!!

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!!

UWE has decided to purchase the Hollis Explorer Rebreather as their choice for their Recreational Rebreather.  Having been certified on the Drager Dolphin Rebreather many years ago, and not having used it in a long time, I have been wanting to dive a rebreather as one of my many methods for diving.  I was thinking of buying and training on the Hollis Prism 2 breathers, but I could not justify the eCCR purchase as I have not had the opportunity to do many technical dives in the past couple of years.  Though I do love photography, and a rebreather certainly makes sense to dive for the quiet affect.

I can see the Hollis Explorer eSCR as a smart choice, easier set up, easier predive, minimal bubbles, with extended times underwater.  Also, the price point is pretty attractive for sure.  My Explorer should be in any time now, though my training does not begin until early April, I am already working on the course material, and intend getting to know the user manual like never before.  I certainly am open to learning more and more about diving and I think this is the best route for me.

I plan on keeping a journal on my training and posting the various dive profiles I will encounter during my training as well as my fun dives.  I am heading to Gods Pocket Resort in May, and my goal is to be fully competent by then so I can dive it and put it through the paces while up at the Pocket.

Be sure to check back and see how my training is going.  I will post open and honest opinions on here so everyone will know how the Rebreather works.
