You are losing me here. You mean to tell me you have never been on a dive boat where swells or change in weather in between dives caused a boat to become rather unstable? I doubt someone is going to tell you that you cant change out your gear but enough "Walters" on a boat insisting on...

We might be talking around each other. I am referring to changing out tanks in between dives. I thought people where on their soap box about crew touching their gear at anytime, not just in port. Keeping customers safe is absolutely their job.

I'm sorry to hear that, I'm sure it was rather frustrating but for every example like this I can probably give an example of divers on dive boat hurting themselves or someone else or breaking their or someones gear simple from not being use to being on a boat. A boat capt is always going to...

Extremely rough conditions. The last thing you want is 10+ people with no sea legs on a pitching deck trying to move 25+ lbs tanks around. Lets be honest the majority of tourist divers aren't exactly fitness studs. Last thing you want to see is a bunch of out of shape divers bouncing off of...

I heard someone say the other day that the problem with decompression models is they are looking for a digital solutions to an analog problem. Probably not accurate at all but thought it sounded good :)

You people are funny :) Things like "Sure let them set it up. Just don't let your family blame the dive shop when you don't come back to the boat." makes me laugh. There is nothing that anyone can do to your gear while it is being set up (outside of breaking out tools and taking stuff apart)...

You kidding me? I love it! I rarely get to be a tourist diver but when I can I do absolutely as little as possible. Let those young DMs lift those tanks for me, sounds great! Of course I am going to check everything once they are done :)

I hope no one in this thread really looks at tourist DMs as anything more then tour guides and sherpa. There is always a chance that you are getting a DM that is 50 dives out of OW. Unless you are fresh out of OW then the only thing of value you should expect from a DM is dive site...

This is interesting, I didn't realize that this wasn't the norm in GUE circles. Most of our dives are drift dives in current so depending on current we may average out somewhere between 130 and 150. I guess we do dive this way as we track average depth and then the deco capt calls out the deco...

Since I completely railroaded the V-planner thread I figured I would spin this off and see if we could have a discussion about the differences between the two. I want to see how many think its minor and can be addressed in an above water discussion or if the differences are so great that when...

Speaking the same language in my mind means being able to integrate into a dive team together. I don't see many differences that cant be worked out with a simple check-out dive together followed by a talk on gases and deco plans. For example I don't think you will find a ton of GUE Tech 1 or 2...

ahh cool, thanks for filling in the gaps. Figured i missed something when talking to my buddy. i wonder if GUE and UTD will ever deviate so much that the systems are radically different and incompatible. Somehow i doubt it.

Talked to buddy who just finished Tech 2. moves from 75% of depth is still 10 ft per min until 50% of depth at which point it becomes 5 ft per min until gas switch. So unlike UTD method of moving half your intermediate stops down to your 50% of depth deep stops GUE is saying just do 2s from...

I think you miss understood what I wrote. 200ft to 150ft would still be 30ft per min. I was referring to the rate of ascent from your 75% of depth to your first true deep stop or your gas switch depending on which comes first. Old GUE Tech 1 method was the 10ft per min rate or the 30 sec...

I got you. My examples and changes were only for Tech 1 ranges using 1:1 RD compared to Tech 2s 2:1 RD where you start pushing time down into your deep stops. I'm not sure if GUE changed 2:1 RD to use 20 ft per minute until your first true deep stop or if it is still 10 ft per minute to your...

You are losing me. You are not extending deep stops to 2 mins. It's add one more minute for an emergency at depth then you are ascending faster through the "deep stops" (not really a good term for Tech 1 depths.) at 20ft per min instead of 10ft per min. I believe this change of ascent rates...

Oh sorry, that's my personal comfort zone with my TDI trimix training using a 70' and 20' bottle, which is of course considered beyond GUE Tech 1 level. I'm not going to pass on a good dive in the 180 range just because I've now done Tech 1 :) T1 I think is the same limits as you mention. I...

Gideon Taught RD with a linear shape. Really his comments were that he didn't care how you shaped it but he preferred linear to keep it simple. I cant tell the difference either so I just stick with linear if the team is ok with it. Of course Im not diving past 180 so take that as you may.

This might also be new but current guidelines are you factor in 1.5 after doing your deco gas plan which only allows for max deco of 25 mins on a 70' for deco. This was new to me as i had been planning deco gas at a .5 consumation rate with no modification. As far as your dive back in the...
