Hollis 500SE Regulator Review

Hollis 500SE Regulator profileWith every new regulator launch comes new “hype”, most of the time I have noticed that most of the improvement is in the visual design.  The new version looks cooler, it’s black and features aggressive characteristics to portray the “Tec” image.  Well this new design isn’t really new at all.  In fact it is quite old.  If I would have seen this a few years ago I might have passed it up for the newer looking round regulators…and I would have missed out big time.

Benefits of the Hollis 500SE

  • Pneumatically balanced servo valve system
  • Patented Orthodontic Mouthpiece for comfort and reduced jaw fatigue
  • Standard with 30″ maxflex hose
  • Easily disassembled without the use of tools and underwater if necessary
  • Left or right positioning – no upside down
  • Boltsnap tie point (Hollis.com, 2015)

Hollis 500SE Regulator backsideHollis has brought back an old design with a modern look and features.  Hollis highlights these features on the regulator’s website (http://www.hollis.com/500se-dc7), the ones listed above.  Of those bullets I feel that there are 2 that need to be mentioned again.

First the statement, “Easily disassembled without the use of tools and underwater if necessary” is an understatement.  I was a bit skeptical when I read this but wow this regulator is unbelievably easy to disassemble.  All you have to do is twist off the plastic nut that holds in the hose and pull the interior of the regulator out…done!  That is seriously it.  This is amazing for cleaning or removing debris.  To go hand-in-hand with that, the service kit is minimalist due to the simple, but reliable construction of the 2nd stage.  I would like to thank Hollis for this design because it makes yearly overhauls simple and time saving.

One of the most important features of the regulator (for me) wasn’t highlighted by Hollis and it definitely needs to be mentioned.  For those of you who know me know that I primarily dive a PRISM 2 eCCR.  The CCR is probably the greatest tools for underwater videography because there are no bubbles that ruin your shots, no giant distortions covering your subjects…just clear water.  This is where the 500SE makes it’s money.  For the divers out there that can’t afford to dive a CCR and want to minimize bubble intrusion in your videos this is the single greatest option…and at a fraction of the cost.

This past weekend I shot tons of video underwater (which I am still scrubbing through) and the 500SE’s performance related to video was fantastic.  At almost no time did the bubble ruin a shot or distract from the video.  I didn’t have to think about breathing during my scene captures…simply amazing as far as I’m concerned.

Hollis 500SE RegulatorSo how did the 500SE perform in the water?  Excellent, and I am sure that didn’t surprise you.  The 500SE breathes extremely easy and I didn’t have any issues with free flows during any dive, ascent/descent etc.  The mouthpiece is very comfortable and I didn’t endure any sort of jaw fatigue or feel any pull or push…the regulator rested perfectly in my mouth and was barely noticeable.

Drawbacks of the Hollis 500SE

I honestly could not find a downside to this regulator.  These regulators have now retained a permanent home on my gear for all my OC dive setups.

Summary

Would I recommend this regulator?  YES! Who would I recommend this regulator to?  This regulator makes deco/bailout tank streamlining a breeze.  It is also great for beginners who want a high-performance regulator that can meet recreational and technical diving demands as well as feel comfortable in their mouths during long dives.  Finally and without a doubt I would highly recommend this regulator to every open circuit videographer out there, especially those non-professionals that implement multiple cams like GoPro cameras on helmets.

Was there a question that I didn’t answer?  Still want to know more?  Feel free to comment below, I love to hear our feedback.

First Scuba Trip 2015

So we finally got back out to the South Korean East Coast to log some dives.  It is hard to admit but this first trip wasn’t that easy to get excited for.  The video from this past weekend (except for the first driving video) was all shot with the GoPro Hero 4 Black in 4k resolution.  If you have this camera and are editing video be prepared for some extremely large file sizes and long upload times to get 4k resolution from YouTube.

Namae ScubaA special thanks to Namae Scuba (www.NamaeScuba.com) for once again providing some excellent dive facilities and diving, we wouldn’t have had a great weekend with out you! Preparing for dive trips isn’t hard just moderately time-consuming since you don’t want to forget anything back home, hours away.  This is especially true since this was the first ocean trip for the PRISM 2 eCCR.  We wanted to check everything multiple times to ensure we had what we needed and everything worked correctly.  We also were preparing for testing out the Hollis DX300 dry suit and the 500SE regulator & DC7 first stage.

Screen Shot 2015-03-21 at 17.22.21Thankfully BOB (bright orange ball in the sky, aka the sun) was out in full effect the days prior to the trip which really helped motivate all of us to start preparing food, equipment and willingness to make the trip.  So was it worth it?  DEFINITELY!  This trip had some of the best visibility that we have seen in a very long time.  Plus we met some new divers Jonathan and Stacey as well as making some new Korean dive buddies (even celebrating a birthday).

Saturday started at a perfect pace, relaxed and fun…we hit the beach to test out new configurations, new equipment and re-familiarize ourselves with our equipment (like the PRISM 2).  Thankfully so because some of us needed to adjust weighting from previous dives and for others this was the first time Screen Shot 2015-03-23 at 20.46.26diving in this temperature water.  So many people ask…”isn’t it cold??”  OMG Yes! It was freezing (on the hands) but our dry suits kept (most of) us warm.  The water was a lovely 6-8C / 42-46F…definitely C.O.L.D!  Thankfully that didn’t stop us from hitting a second dive on Saturday to explore the dive site West Ridge (13-24m deep) where we say great viz around the artificial concrete cube reef.  After we got back from the dive we cleaned gear grabbed some coffee and dinner in Gangneung to relax.

Sunday started early with some of us getting up to watch the sun rise and warm our faces…others decided to Screen Shot 2015-03-23 at 20.51.21sleep in a bit before our 0930 dive.  This dive is one of our favorites, early morning, very calm and our favorite site…Steel House!  This site has 3 giant 10 meter steel structures that are approximately 25m apart attached by rope to easily find each other.  There are lots of new growth and during the summer months lots of fish around the structure.  As we descended on the steel structure we were astonished by the amazing visibility we had.  The water was simply amazing, blue, clear, and no surge or current…amazing!

After the dive we warmed up and cleaned equipment in preparation for the long trip home.  We thought we Screen Shot 2015-03-23 at 21.05.45would beat all the traffic home however there was a huge forest fire that spanned the expressway on all sides which slowed all traffic down to a grind.  It did provide a great opportunity to capture some cool video of 8 or so helicopters gathering water from the local lake to help put out the fire.

For those of you looking for the Hollis DX300 review please check back later this week.  We will post our thoughts on Hollis’s newest drysuit.
