UWE was out on Saturday night diving the Hillis Explorer Rebreather at Porteau Cove.  We followed an easy compass bearing out to the the fire hose and then turned right and followed it to the Jungle Gym, and then we stayed at about 50 feet heading out past the Granthhall.  The dive went very well.  We had one diver in Sidemount, then and another in doubles and me, well you guessed it, I was on the Hollis Explorer.  The rebreather performed very well, though I think battery cell number three is having problems.  I have been dealing with Gus at Hollis trying to figure out what the issues are.

Porteau Cove is an awesome dive site with so much marine life and artificial reefs that it is so much fun to check everything out, especially on a night dive.  I am off to Ontario for the week, so I will land locked for a little, but  I will be back at it next week!

UWE was out the other night diving at Whytecliff Park on my Hollis Explorer Rebreather.  The conditions were not the best, but as we descended deeper the visibility improved drastically and we had an excellent dive.  We descended in about 30 feet of water and headed down the slope.  The visibility was about 20 feet.  As a slide along the sand with the rebreather, I was once again treated to the cool things that my Hollis Explorer Rebreather allows me to get closer and closer to the marine life without scaring them away.

Our dive lasted about 60 minutes, I want to say my unit performed flawlessly, but I can’t.  Since I had the head, handset and hud replaced I have been having battery problems with the unit.  I keep it on charged, and when I put the unit together it’s fully charged, I have been having 0 battery ascend immediately warnings.  The unit had been off charge for about 1.5 hours by the time I hit the water, then 60 minutes later I had the “Ascend Immediately” warning, though it’s impossible that the unit had last power that quickly.

I knew the system would have it’s problems as I know it is still very new on the market.  I have to say Hollis has been very supportive, and I have been dealing with Gus, who has been fantastic.  If you want to try something cool….come dive the Hollis Explorer Rebreather!!

UWE  was out diving at Porteau Cove, enjoying their Hollis Explorer Weekend.  We set the Hollis Explorer up on the day before, ensuring that all appropriate check lists were followed.  We did a quick negative pressure test, just to ensure the final checks the next day would go off without a hitch.  I noticed after trying to take the Hollis Firmware update the HUD was not working 100 percent.  So, the big questions was weather to cancel the dive on Closed Circuit and dive regular Open Circuit.

I got out to the Porteau Cove, and completed the Pre dive series prior to donning my gear and I notice the HUD still no acting properly, though it was running.  Deciding to ensure I paid close attention to the handset I decided to try the descent.  Rene and I decided to enter the water at Porteau Cove by going down the stairs since the tide was way out.  Once entering the water we descended right at the beach level and started out in the main area of the dive site here at Porteau Cove.

The HUD flashed up right on descent and started to work properly for me so it was off to the dive. The

conditions were fantastic, with visibility ranging between 10 and 40 feet at depth.  We spent about 2 hours underwater, and with me diving the Hollis Explorer, I was able to get very close to the marine life without disturbing them.  The Explorer worked flawlessly, and I am very happy with the purchase. I have been having some minor problems with the unit, but Hollis, Gus specifically has been awesome ensuring that Hollis stands behind their unit totally.

I will be leaving for a trip to Port Hardy to stay at God’s Pocket resort to get a weeks worth of diving in, and I am planning on bringing my camera and my new Hollis Explorer Rebreather!!

Interested in diving Porteau Cove, need information on the Hollis Explorer, let me know and I am more than happy to give my advice, and dive briefing.  Either email me here, or stop by Ocean Quest and we can have a chat about your diving needs

Diving the Hollis Explorer

This past Sunday had me out diving the Hollis Explorer Rebreather.  I have been chomping at the bit to get out and dive my Hollis Explorer.  I finished the Advanced Rebreather course on the 3rd of April and while changing in the parking lot, I was hit with Sudden Sensorineural Hearing Loss, or Mennier’s Disease.  Though the diagnosis will be clinical with no conclusive evidence of either, it has kept me out of diving.  I finally tired of being out of the water so I decided to dive on the Sea Dragon Charter I had arranged on Sunday, and I brought my Hollis Explorer with me.

It had been three weeks since my last dive, so I was a little nervous maybe in the set up, as this would be my first dive since the course, and though the Hollis Explorer is easy to set up predive and then dive, I still wanted to make sure things went off without a hitch.  Though stupidly I decided on Friday to try and take the Update for the LSS from Hollis (V 4.2).  What a mistake that was.  Each time I tried to run the update, things would only load to a certain point then freeze up.  Each time I had to unplug, and then plug into power and walk away to hope it would reset.  It did, and I tried to update a couple of times but no luck.

One thing I discovered was that I should have thought through how busy the morning would be the day of the charter since I was the one that arranged and organized it.  I got to the Dive center at 6 am, so I could pack the scrubber and finish the set up, attach the head etc.  I figured once on the boat I could do the pre-dive and pre-breath.  This was very difficult as it seemed every time I started the pre-dive, I would get called away to help one of the customers on the charter.  After about the third attempt, I decided to skip the first dive so I could get the pre-dive completed without interruption.   Once I got everyone in the water, I started the pre-dive and discovered it was not holding the evacuation test.  On three different occasions, it failed, so I tore it down to bare bones and rebuilt it.  On this occasion it finally passed though everything looked correct, something was wrong.

We jumped in on a nice deep wall, where we went with to of the Dive Masters in Training, Roland on Sidemount and Amy on a 100 cuft cylinder.  We settled on 80 feet and just slide along quietly and enjoyed the scenery.  The Hollis Explorer is a dream to dive.  Everything I did three weeks ago came back quickly for me, and I noticed my Buoyancy was even better then last time on the Hollis Explorer.  I left my DCP in auto this time, and I had no issues with the solenoid firing and wanting make me positively buoyant.  It was great, at about 25 minutes in on the dive at 80 feet, I was still showing 40 minutes on NDL.  One of the things I found interesting, I read a few posts on various websites with people complaining that the Scrubber was only allowing 90 minutes of dive time though the scrubber is suppose to be good for 120 min.  Mine worked fine, though when I first hit the water, it said only 90 minutes, but that did not tick down for sometime and when I exited the water after 60 minutes on diving, my filter indicated about 70 minutes of scrubber life left.

Overall I am very pleased with the Hollis Explorer and I am looking forward to dive her some more!!

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!!
