A truely amazing bit of kit, so simple to set up and so simple to dive, after just a few days training you will be amazed how much more you get from your dives.
You can stay longer, get much closer to marine life, warmer as you're breathing heated air, less tired as you are not breathing dry cold air like on open circuit. You just see more.
The Explorer is a hybrid rebreather using a single Nitrox gas of 32-40%. It's not a fully closed or semi closed rebreather it's a hyrib giving you a simple, safe, no fus, lets go diving rebreather. Great down to 40m.
Compact, light weight and easy to fly with. I fit mine in my carry on bag when I fly or 3 units in 2 gear gulpers when I am teaching.
The Explorer is electronically controlled to achieve an optimal balance of PPO2 and dive time. Simple sofnolime absorbent cartridges that after training you can pack yourself, a big advantage when travelling, Great simple handset guides you through your pre dive check with plain english instructions not code numbers you have to look up, The Optional CO2 sensor and makes pre dive even quicker with a simple 1 minute pre-breath instead of the normal 5 minute pre-breath making the Hollis Explorer even quicker to get ready.
The Scrubbers are the bit that removes Carbone Dioxide from your recycle your exhaled breaths and allowing most of the Oxygen to be reused, instead of wasted and lost when you exhale. The Hollis Explorer scrubber are easy to learn to pack yourself or you can use pre packed scrubbers if you prefer. The option to pack them yourself is a major advantage when travelling around the world and saves you money.
The unit Scubber has an approximate 2 hour duration. It is CE approval is for a minimum of 90 minutes, 40m at 4 Degs. This can vary depending on exertion, Gas, temperature and conditions. You will learn about this when you complete your training on the unit. The Unit also monitors the temperature of the scrubber using US Military technology, Giving you a good indication of scrubber usage or any problems.
Excellant built in dive computer with a clear, bright, backlit Display very easy to see underwater, although sometimes hard to see on l and in bright sun light but that goes for most computers. The handset screen is bright, vibrant and easy to read even in the murky depths of your favorite wreck, reef, muddy puddle or azure blues of the sea. The handset is connected to the Hollis Explorer by a cable. The Handset / computer can connectted to your PC with a cable that is provided to enable you to download your dive data. The same cable is used to update the handset (computer), LSS (Life Support System), probe and Co2 sensor firmware / software, very simple to do.
The Hollis Explorer rebreather also has a HUD or Heads Up display has a 3 Multi Colour LED setup which sits in front of your mask giving you a simple easy to see system status. This status is also repeated via more LEDs on the LSS that other divers can see from a distance, so your buddy can see you good to go and safe while diving.
The Hollis BOV or Bail Out Valve on the Explorer (see picture) is a dual purpose valve allowing you to breath on the loop when using the Explorer as a rebreather or as a normal second stage if you switch to open curcuit in the uinlikey event you have a problem. So you do not have to remove the BOV from your mouth to switch from the loop to open curcuit when diving the Hollis Sports rebreather.
The Hollis Sports Explorer rebreather is designed for recreational diving - Designed for none deco dives down to 40m and upto 2 hours or so. 40m (and shallower!) where all the good stuff is and where coming to the surface is still possible. If you are looking at deeper or longer, you may wish to consider a full Tec rebreather such as the Prism2. The Hollis Explorer will however calculate emergency decompression stops as you would expect from such a great bit of kit, should you accidentally overstay your time.
The Hollis Explorer has back mounted counter lungs protected by a hard plastic back for safety making it mush easier to put the unit on and take it off. About the same weight as a 10Ltr cylinder open circuit setup but giving you proformance that out lasts twinset with 2 x 12 ltr tanks!!
Very simple and easy to strip and clean taking just a few minutes, the simplest Rebreather I have ever dived to strip and clean.
A comfotable breathing loop is provides a very positive experience. The Hollis Explorer automatically purges small amounts of water that may get in the loop and when ascending or the counter lungs are too full the units vents gas helping you control bouyancy. People of different stature and lung sizes are very cleaverly catered for by the LCV (Loop Control Valve) Just dial in your size of lung and away you go. Providing minimal bubbles and helping to ensure good neutral buoyancy.
The Unit comes with a Hollis Tec style harness, Back plate and Wing BCD (one size fits all) OR a traditional jacket style BCD with intergrated weights available in various sizes.

So what did I think for the Explorer. I started the pool work and classroom work in Dec 2013.
At first, it appeared to be a little confusing, but very soon I was put at great ease by my Instructor.
From then on, What a great course. You soon get to grips with the building of the kit and the pre-checks, and the more you use and dive with the unit, the more you get to enjoy it. I was lucky to be able to complete my open water dives in Malta, which I did in Feb 2014, and we did have a few extra dives as well. The first thing that hits you is, NO BUBBLES, It is so so quiet. The warmth from the unit, that is a big help, and you don’t get out the water and drink the whole bottle of water, as normal with your old open circuit. My last dive in Malta, I went back on to open circuit, OMG, the noise, I was cold within about 45 minutes, and YES, drunk tons of water after the dive.
I used the unit in Truk Lagoon for 6 days. 19 Dives and the unit worked with no faults. The performance was brilliant, it’s a great, robust unit, and it Truk it did get a good workout. The Soda lime is very easy to change, so are all the other parts. There are plenty of safety features as well, which one would expect.
The diving in Truk, my buddy was using twin 10/12 litre tanks. Most dives where between 35-40m and you can soon clock up some deco stops. In a general rule, my buddy would have about 30 mins deco using open circuit, and using the Explorer, I would have about 10-12 Minutes. The plus side, It’s the small amount of gas you use, 5 Litre in the unit and a side mount –COOL. When you check the log on the Expoler`s computer, COOL, it tells you that you have just used about 90 Bar !! On a 5 Litre. Now work that out, It’s a must have bit of dive kit. The trip worked well, as my buddy on OC had to wait a few minutes more for me to complete the pre-dive checks and pre-breath, but underwater, you always have to wait on the stops for the open circuit divers (never leave your wing man)
All in All, A fantastic bit of kit. I think it is quite well priced as well.
There are the normal pros and cons, which the instructor will explain to you, with respect to the other units on the market.
How would I rate the course & Explorer?
Ease of use 9/10
Build – 8/10
Display / Computer 7/10 – A little hard to see in strong sun light, and sunny shallow dives
Looks 6/10 – A black back cover would look better.
Cleaning / Building 8/10
My recommendations. Put your open circuit gear to one side and get on this course!
NOTE FROM TAL SCUBA - PLEASE NOTE THE EXPLORER IS DESIGNED FOR NONE DECO DIVING WITH 32-40% NITROX.
- The Hollis Explorer is an awesome bit of kit! - so simple to use and dive
what a fantastic time this afternoon! - The Hollis Explorer is an awesome bit of kit! - so simple to use and dive.
