Is DUI overrated? My shop is asking $3.5k for a custom cut TLS350.
I have reservation because I've witnessed several instance of new TLS350 leakage.
This is not hearsay but from people I dive with.

I have a custom fit/cave cut Signature Series TLS350. I consider it some of the best money I ever spent. I love it.
 
Compared to the Diamond trilam I own, the TLS fabric is MUCH thinner and less durable. I have never been a real DUI fan simply because I think compared to other suits they are over sold and much of the purchase price is for the "DUI" patch.
 
Your post should answer the question :)
 
Yes ...
 
I have to admit that I love my DUI drysuit as well. To be honest, I have not tried other dry suits so I have nothing else to compare it to. When I started cave diving all of the guys I dove with had DUI suits so I got one as well. I have no complaints about it but I have not done much consumer shopping to compare it with other suits. People on SB seem to like the Fusion suit as well.

To answer the original question, I think 3.5k is a little steep. Mine was cheaper because a buddy of mine owned a dive shop and they were a dealer. Custom suits will run a little more. I think overrated is a subjective point of view. For those who enjoy their suit and have had few problems with it then they would say no they are not. For those who spend more time at the post office sending their suit back than they do diving then the answer is yes. The other question I have is where did the suit leak? At the valves? Through a hole in the suit? Both of these are easily repaired and should be under warranty if it's new. DUI's customer service has been great the one time I used them so I have no complaints. But to decide if something is overrated or not is a personal decision based on your experiences. For me it was not.
 
Here is my usual answer to the what drysuit is best question:

First, let me warn you, there are few issues in diving that have more opinions backed by less data that dry suit selection. I doubt if there are more than a few divers on the board here who have, long term, dove more than one or at most two different designs of suit. Dry suits are very expensive items and folks get real ego involved when they make multi thousand dollar decisions, if you know what I mean. Most folks dive what their instructor or LDS tells them to, and unfortunately most Instructors have limited dry suit experience and most LDS only have one or two brands of suit to sell you and don’t really understand the advantages and drawbacks of even those suits. Let me give you an example, drawn from the question of wetsuit selection, but it addresses this problem and should help you to understand what you’re up against:

I issue a very detailed equipment list before each class that students who are accepted into the class need to purchase and show up with at the first meeting.

The suits we were using at the time were, as I’ve mentioned elsewhere, 5mm, skin two side, Rubatex GN-231N, attached hood, farmer johns, no zippers. I send my list to all the LDSs in the area and freely distribute whatever they send back to the students (this is a big deal to the shops, in the dead of winter, twenty full sets of gear with no selling or inventory required: take the order, take the money, and deliver in two weeks).

One student did not go to an LDS, but rather to a shop near her home, about a hundred miles away. I got a call from the Instructor in the shop informing me, in a fairly emphatic tone, that, “No diver could possibly wear this
suit. They could not put it on without a zipper.” Now, please understand that I’ve been diving this suit design since the mid sixties, and the only people who need an inverted half zipper in the jacket are incredibly curvaceous women of petite statue. This woman was just shy of six foot, very athletic and quite thin.

Having nothing better to do (and considering that the woman in question was one of the brighter marine geologist grad students), I drove up to the shop later in the day. I brought my
suit with me. I showed the Instructor how easy it was to put on and take off, etc. We solved the problem, but the bottom line was that this Instructor, well meaning as she was, had not yet worn out her first suit and was repeating what her Instructor’s had told her. It wasn’t a marketing issue, the LDS could and did supply the gear (and nicely matched the prices of the LDSs that had sent fliers).

The bottom line is that for dive gear, real information is hard to come by. Most of the opinions that you see on the net are biased either by being the only piece of that class of gear that a new diver has ever used or being a loaner that the expert tried out on one or two dives.

The thing that you need to do is find an expert who is doing the kind of diving that you plan on doing and ask him or her about the gear. That may well not be an Instructor. Don’t be afraid to bore on in, why … why … why. If you do not get answers that you understand, find another expert. Make sure that the advice makes sense in terms that you understand. When it does, buy the gear and never look back.


With all that said, I really can’t advise you until you define the diving you want to use your new suit for, but here are some thoughts:

Crushed, laminate and vulcanized suits have no inherent insulative properties so they are totally depended upon underwear and gas trapped in the suit for insulation. As you descend you add gas to the suit and that keeps both buoyancy and thermal characterizes constant.

Uncrushed neoprene (and please understand that there is a HUGE difference between the neoprene many
suit manufacturers use and quality Rubatex in terms of compression) will crush with depth, but not 1/2 at 33 foot, 1/4 at 99 ft, etc. As is does, you must introduce gas into the suit to maintain neutral buoyancy, just as with a membrane suit, and that keeps the insulation about the same.

Which is best? I don't really know. I've had Unisuits, Jetsuits, Vikings, DUIs, and a Polaris (Rubatex
suit from a small Santa Cruz custom house) over the years. I currently have the Polaris which I prefer for shore diving, a Viking for polluted water (nothing else can really be disinfected) and a DUI that is a joy for boat diving. I use an old set of Unisuit woolies under the Polaris and a ripstop/holowfill/synthetic pile (the blue and gray stuff) set of Viking underwear under the Viking and DUI.

For protection from the rocks the Polaris is the best, for minimum drag while swimming the Viking wins hands down, for ease of in and out, the DUI gets the nod. For ease of repair, it's the Viking. There is one thing that I have in common on all three suits: SiTec wrist rings (which I use with wrist seals) and SiTec neckseal/dogcollar/dryhood system. I can easily introduce air into the glove by raising my hand and wiggling my fingers (this lets some air past the latex wrist seal) and I can get air out by careful “burping.” The neckseal system allows me to throw away a torn neckseal and have a new one in place in seconds, and the dry hood adds a lot of warmth.

I've yet to find the single use that the tilam excels at, it is light, packing away small for travel, and dries quickly, perhaps it’s advantage is being second best at everything … no small feat.

No question, if durability is the only issue, a Viking HD (or equivalent) is the suit of choice. A viking style suit (viking, gates, avon, etc.) will take the most of that sort of abuse since the material does not wet (it is also the only style suit that is as "good as new" after a field repair.
 
I recently tried two DUI suits (TLS350 and CLX50/50) at one of their DOG Rally Days and disliked both. suits leaked. I realize that this is a function of having a limited number (and sizing) of "test dive" suits, but both suits leaked. Additionally, the TLS350 felt like diving a hefty bag, even with a substantial undergarment.

After shopping around, I decided upon a Pinnacle Freedom2, and couldn't be happier. No bells or whistles, but a dead simple and - so far - rugged self-donning suit with a bulletproof zip and SI valves.

For $3.5K I could buy SEVEN Freedom2s (granted I got a great price).

Just like the blue "H" - I will not pay a premium for a specific brand.

Your mileage, of course, may vary...

Best.
 
Is DUI over rated? I guess it depends on who you ask. I have a custom TLS350 and it didn't cost that much. The cost was $2200.00. As far as the suit goes I love it.
