Discover Rebreather

By Brian Rossman

Last Saturday I had the chance to do a discover rebreather dive at an area pool with Aquatic Adventures of Michigan. I got to try out a Poseidon MK VI. Both Tom and Steve are very knowledgeable and were very helpful in answering any questions.

Having done a fair amount of research prior to taking this and listening to the presentation at Great Lakes Shipwreck Festival I expected that it was going to be something I enjoyed. I underestimated just how nice it really was.

First off I am a bit of an air hog. My SAC has been improving over time but it is still a bit high; on a CCR this is no longer an issue. Longer bottom times and less weight to haul around. Both good.

Fixed PO2: Having a good understanding on the benefits of nitrox – mostly more bottom time. The CCR takes the benefits to its max while not impacting max depth the way nitrox will.

Weight: Diving HP120 tanks when doing open circuit the weight difference is amazing. Less gear to move to the dive sight, the gear you move weights a LOT less. The other thing about having less bulk is I felt way more maneuverable in the water. The ability to flip, roll, and hang upside down was great fun.

Only drawback was that, as the instructors pointed out, buoyancy control is totally different. I had some major issues initially with starting to become positively buoyant when I didn’t want to. I had this mostly sorted out by the end but I know it would be a major focus when I take the rebreather class.

The price isn’t as bad as it might seem if you plan on diving enough and with tri-mix. Which is my intent in time.

All I all I loved the experience and have added a Poseidon 7 to my wish list and the class as the next one to take after I take shipwreck and deep.

My SCUBA wish list would really be helped out by winning the lottery even more so than before.

1 lost year of diving, 1 or 2 more to go.

Well I just realized that I haven’t updated this in some time. I also noticed that I only got 6 dives all last year. On top of all of that, I even paid for a wreck diving class that I never got to take. I’ll have to make sure I fit that is some how.

Quick update. My work obligations due to our current mission basically take 2 months out of the summer. Plus one weekend a month. So I’m really looking at a very constrained schedule to start with. Add on school and that I’m a broke student and it gets even worse. This however will come to pass. We are on the mission a limited number of years and I will graduate with my BS of Computer Science December 2014. I’ll just have to get in what I can fit in until then.

On the plus side I seem to be able to make it to more shows this off season than last year. I made it to the Shipwrecks and Scuba in November and enjoyed all of the programs as usual. Most of the speakers they get every year are really top notch. This year’s keynote was amazing. Fabien Cousteau is a very dynamic speaker and was there in person rather than remote from Aquarius thanks to the government’s inability to keep running.

I’m also going to make it to Great Lakes Shipwreck Festival later this month. I’m really looking forward to it. I missed that show last year because of NG drill. And as the year before that. I haven’t figured out which of 2 speakers in the same time slot I want to go see.

I need to update my digital logbook on here as well.

Can someone please add 6 more weeks to the summer?

By Brian Rossman

Can someone please add 2 weeks each to June, July, and August?

It seems between the weather, work, school, and the National Guard this is not going to be a good season for me.  I got a March Dive in.  The April flew past… Then May… Now I’m away for training, will have a 3 week break, then more training.  I hope next summer will be better.

I could look at this as a sign to scratch up the money for a dry suit, but the school thing also equates to a lack of random extra money.

I have gotten my techBuddy from the Blue Buddy Kickstarter but so far it has remained as dry as I have.  The interface and construction look great.

First Dive of the Year

By Brian Rossman

I finally managed to get into the water for the first time this year.  I headed down to White Star Quarry for their unofficial opening on March 30th.  There were several things I was hoping to accomplish on this dive and I got part of the way there.

Dive Log:

Dive Number Entry Time Bottom Time Max Depth
1 11:33 28 min 45 ft
2 13:41 28 min 49 ft

Goals for the day:

  • Get in the water
  • Try out a Whites Fusion Dry Suit
  • Test my SCBT for the first time in the water
  • Work out trim weight for diving with 30 cft pony.
  • Meet new people

I had called a few people that I have dove with before and they were not interested because of the cold water.  So I drove down knowing that I would be able to dive with someone.  Before the weekend I really didn’t have time to prep so I was a little rushed and managed to leave one of my integrated weight pockets for my BCD.  I pack enough extra weight that I just moved more to my belt and solved that issue.   It did however prevent me from testing my pony weight and trim as I spent more time playing with my buoyancy than I had planned. There was some thin ice when I arrived around 9:30am but that was long gone by the time we got in the water.  I ended up diving with an instructor that was there alone with the same thought that there would be someone to dive with.

I have used dry suits before but this was my first time with a Fusion and I’m totally impressed.  All other things being equal I found trim orders of magnitude easier.  That is about the only major difference I found between that and the DUI Tri-Laminate that I had used in the past.  Between this and the price this is without a doubt the route I’m going for purchase.  (Now accepting donations for my dry suit fund).

That covered my first two goals.

The SCBT did not go well.  It seemed to be running fine for the first part of the dive, then it just shut off.  The iPhone was totally powered off.  When I powered it on I made it to the lock screen and it shut down again.  There was no indication of water (This was later confirmed by looking at the moisture indicators in the phone).  The log in the app was 0 time.  The most likely cause was the temperature change.  The air temperature was around 50°F and the bottom temp was 37°F.  It looks like the temperature change may have caused a current drop in the battery output shutting down the phone.  I did not both trying to test it again for the second dive.

I met a few new people that I hope I’ll have many chances to dive with in the future.

SCBT Black #38

So I managed to extract my Scuba Capsule Beta Unit from FedEx.  I do have to say I really, really don’t like dealing with them.  That being said I drove to FedEx to get it Monday evening.

Nice BETA label on the box and hand written number and color on the box.  I’m not sure why I liked this so much but it really makes me fee like I’m in on the ground floor of helping to get the best app possible.

In side was the unit inside a nice case.

Tested the unit real quick and provided a few bug reports.

In general the UI needs some tweaking as to sensitivity and I have found a crash bug.

I won’t have a chance to get this underwater for a while and with the UI in its state I would probably use it just on the main screen.  The developers are making bug fixes on a daily basis so I would expect this to make major improvements very quickly.

bluebuddy – Kickstarter compleeted

By Brian Rossman

The bluebuddy has finished its Kickstarter campaign with about 1.5 their target funding.

I ended up pledging for the techbuddy.  It was a little more but didn’t need to worry about exceeding it’s range ever.  I am a little disappointed with the extra features in their app.  Most iOS using divers have been using Diving Log 5 for some time and there is nothing convincing enough about this device to convince me to change over and having the extra app seems a bit odd.  That being said they do state that they use the BLE API for the data exchange.  This might be something to look into deciphering how they implemented the pairing and communication and see what other logging apps might support downloading from this device.

So close…

By Brian Rossman

FedEx was just a little too slow.
So I won’t be able to test in the water for at least 2 weeks…

SCUBA Capsule finally shipped! This is great news. And its already at my local FedEx. But because it is in a container that isn’t being delivered until Monday there is no way to get it until then.

Not a huge deal if it were not for the fact that I have National Guard next weekend and no free time during the week. Time to try and find someplace to test the weekend of the 16th. Which isn’t easy this time of year in Michigan.
