Hollis Explorer vs Poseidon MK6

I am not so sure. Certainly some of the sales are related to dive centers, as rentals. But I dont think any store manager would invest thousands of dollars in a single unit just to have it on display.

We did, dealer stocked units do count as sales to the Mfg. People need to have the ability to touch one to begin to consider diving one.

But I dont think any store manager would invest thousands of dollars in a single unit just to have it on display. I do not see any difference here to any other breather. But just say that 50% of all units goes into indirect diving. That would still mean that there are 1000 units out to divers around the world. Not bad considering the short time it has been available on the market.

You missed my point Jeppe. The initial sales are to the people who will be training the users, as are the initial courses. As the market for these, being recreational dive centres (who will need qualified trainers) is bigger by an order of magnitude than the market for technical trainers (who are further diluted by being limited to one or at most a few units) there will naturally be a much bigger market for the rCCR's.

Sort of like the amount of dealers there would have been for Ford when the model T came out versus the independent coach makers who hand built cars.
 
Quite a few dive centers are doing training on the Poseidon and I suspect a lot of divers getting the training will never buy a unit. It makes sence if hire units are available and you only do holiday dive which is the way a lot of recreational diving is done, so that market will be a lot bigger that the Tec side ever will.

That said I suspect the Hollis will have some advantages on the rental side as its an SCR the support & training is a lot simpler, so once Hollis get there act together and finally start shipping (Don't hold your breath) they may sell quite a few.

If your planning to own a rebreather I can't see there is any contest, the Poseidon will grow with your diving. Out of the box its better for duration an depth the the Hollis, and the current upgrades take you well into TecLite diving.
 
The marketing of the MK6 was fraudulent end of story.

Wow! Now that is the biggest BS I have read in a long time!

I certaintly can understand how one can have different oppinions on the MK6 as such and sure the marketing is what it is: Marketing and as such full of a lot of "questionable" phrases..
But fraudulent ?? That is way over the edge !

Ah, yes of course, that makes perfect sense.
 
I did 2 try dives in january on the Explorer. I enjoyed the unit very much. Also I rent from time to time the MK6, will do so in 2 weeks, so I can say that both units are great in recreational dives. MK6 for sure longer NDL, but handling from the Explorer is really easy. And honestly I find the price for MK6 (or 7 now) far too expensive, again for REC market... Anyway, deeper then 30-40 m I take my Sentinel. Cheers,

short news. The renting MK6 turned out as fiasco as on 2 dives I had C1 and C2 errors. On roughly 40 dives I had now 4 missed dives which is 10%. Also I realized that OTS counterlungs is really not my cup of tee, so stopped it and went OC.... Conclusion: if a sport rebreather I will go for the Explorer. This is of course just my very own opinion. Cheers, P.

Well,that is a bad experience. Strange though, that you got C1 errors, might be cause it is a rental. Most recent software and fresh cells should prevent this. I am now on my 51:st dive without any issues at all. In total I have had 2 C1 errors which lead to a Bailout, on 91 dives.

Well, looking several videos of Explorer divers, it seems that the unit produce far more bubbles as expected, I guess in very shallow depths with poor nitrox mix, but still I'm not convinced anymore... Maybe I should built my own travel unit...

Yes, On the surface or in shallow water with a light O2 mix the Explorer will add a fair amount of gas to keep the look breathable making it seem like it is bubbling a whole lot. Remember, it is looking at the loop contents and only injecting when you need O2. Once you descend and the PO2 is high enough, the Explorer can dial back the injection rate. I don't know why this would be a negative for the Explorer.
 
Not negative. Just want to make as less as possible bubbles. Anyway I will witness a try dive on Explorer in July, so i will see with my own eyes how many bubbles really will be. Saying that I enjoyed the unit very much on my try dives...
 
finally did my course on the Explorer. Believe me or not: I pushed the unit to the limits and decompression was same than CCR. Instructor was on JJ and had 2 minutes on 6 meters and I had 1 minute on 3m with Explorer, both disappeared on the quite slow ascend. Also I had as "backup" a Shearwater Predator that I used in CCR mode with set point 0.7 til 18m and 1.2 from 18m deeper to compare and it showed same deco as the JJ CCR. We used nitrox 37% and at 34 m the unit triggered alarm to ascend. In all the Explorer is perfect for 80% of my dives, now I safe money as I cannot separates myself from Boris and sentinel.
 
Great Pat, sounds like you had an instructor that knew how to work the controller and was able to teach you what you needed to know. We have been running the Explorer offshore on spearfishing trips and have reduced the weight per diver by a couple hundred pounds. The Explorer works perfectly for these types of dives also.
 
well it's all so damn easy with the Explorer. I had SCR and CCR background, so it is really no big deal for me. For weight I used 11 KG in all, so make the rig dive ready in cold water with trilaminate drysuit and Otter 200G undersuit: +- 30 KG.

1.628 ppo2 for the scr what was the set piont on the jj .:hehehm:
 
there is no set point on ESCR, but I checked the PPO2 of course, he was 1.4, JJ I don't know, guess 1.2 at 34 meters...

thanks for the reply ,

ps 34m on nitrox37 , ppo2 may well have been 1.4 when you looked , but that will have been after you breathed the hot nitrox mix down ,

no problem with breathing the hot mix from me , but cant take the deco stuff as fact with that big variations in ppo2 / set point .
 
yes that's also what I thought. Of course when running the unit at the edge, a constant look at PPO2 is mandatory. I don't think he will increase much even with triggering the ADV, except if you completely purge the loop.
