Well, at least Greta would likely mop the floor with little sweet thing. Heck, she might be able to even kick my butt! So I’m ok with this comparison 
Very cool! So did he admit defeat? Anyway I’m glad to so your BTU held its on in the light-off. So are are you cool with the BTU now?
rdrfronty will take your BTU if you are not happy with it. 
He admited defeat but during the day he was whining that it wsnt dark enough or his battery wasnt charged enough etc
and yes im cool with my btu . its a showoff light for sure
u keep your paws off my btu fronty 8)
- i replaced all the springs on the battery carrier with thicker ones
the original ones are not holding the battery tightly .just pull them outwaards and you will realise how soft and squishy they are
Nice mod. I’ll be sure to keep that in mind if mine give me any issues.
NEW UPDATE Tk 75 vers BTU SHOCKER
so we decided to go out to a darker place and test it out again today Over a large field instead of a parking lot …Tk 75 battery was also changed to the fenix 18650 and the fenix turbo seems to have become bit brighter!!
we tried at long distence and close up shots
both seems to have similar output
with the btu SLIGHTLY OUTDOING the tk75 in throw .
SO ITS MORE Of WIN BY DECISION FOR THE BTU NOW!!
Actually after owning SR95S UT that have 250kcd that have very obvious better throw than TK70, I can tell you her advantage diminish after 200m as we can’t see that far. Although those within 100m will be brighter because of better throw, but TK70 throw is already bright enough and flood better. So for a 1000m vs 600m thrower I have, the realistic practical gain is only maybe 100m from distance 100m to 200m.
And BTU vs TK75, the practical gain in throw is even less. For quality in UI and material, TK75 is the one to get. For modding purpose, BTU is the one to get. For newbie like your colleague, TK75 is right choice. And you are right to get BTU since you can do modding on it.
yes true . i ordered the dry driver
im weighing my options wheather to change driver or not 8)
I get my TBU Shocker today… by DHL
Thanks for the nice and objective review. Your pictures told thousend of words.
The choice is up to you…
Firstly I would like to buy the Xtar S1 or the Fenix TK75…. after read your review…. I changed my mind….
Now I like the TBU Shocker: big, heavy and solid quality! I can’t wait for longer… DHL… where are you now!
I ordered the DRY driver after received the TBU after 4 business day.
When receive the DRY driver, I’ll change it… for more light!
I thought someone already tried DRY driver in BTU, it is not improving much.
YUP .I changed mine few days ago . not much improvement. same output . changed back to the digital driver now .it drives at 3.8 amps and the dry is at 4 amps??? .. have a good soldering iron ready if you do change. its a bit of a chalenge to change the driver .you can end up screwing up the good digital driver. the dry driver is cheap. THE ONLY THINK I LIKE ABOUT THE BTU NOW AFTER USING IT FOR A FEW WEEKS IS ....THAT I CAN UPGRADE IT OR REPAIR IT EASILY...NOTHING ELSE. THATS IT . I RECOMMEND A TK75 IF YOU ARE A NEUBIE .
All I can say to that is no other LED light on the market offers the combo of throw and power of the BTU U2. Simply put, if this light doesn’t impress you, there is nothing out there that will.
Sucks that I have the NW version because it doesn't impress me.
In turbo the DRY driver runs in direct drive, so the amperage totally depends on the quality of the batteries. If you used IMR, you could probably get 6+ amps to each LED and possibly blow the thing up if you wanted.
Just curious, but could you elaborate?
It's huge so when you pick it up you think holy cow this thing is going to be like an HID but it isn't. It's a cool conversation piece but the TN31 beats it for throw and the TN30 spanks it for flood, and by the looks of it the TK75 beats it overall. I need to do some further testing in an open area against my other lights to give it a far comparison though.
For the size of this light and the three c8-sized reflectors it should blow my socks off. It might be because I have the NW version?
Even though there’s no point arguing opinions I just want to say that even though a TN30 will beat it for flood and a TN31 will beat it for throw, what if you want both the throw AND the flood? We don’t have any side-by-side comparisons of the CW and NW together, so we can’t be 100% certain you would be impressed by the CW. I’m using the Shocker daily for my needs and I can say that it does meet my illuminations requirements (and surpasses them by a lot), but I do agree it is too big. I’m getting a bit bored of it now, and want to get an insane single emitter thrower now.
Bottomline: It’s not a light for everyone due to the size, weight and output, but it beats carrying both a dedicated flooder and thrower since it combines them into one.
That's what I meant by "overall" for the TK75. I have no doubts the TK75 is a much better light than the Shocker. I just can't justify spending that much on a flashlight that doesn't have XM-L2 emitters right now.
Please dont get me wrong ...The BTU is an IMPRESSIVE thrower/flooder light !we all agree with that but the overall thinking we have is when holding it in our hands ,,the sheer size and weight gives the impression that this thing will shock and awe but it dsnt ...Iv held the tk75 in one hand and held the btu in the other hand a and the tk75 is very light weight compared to the btu ,and yet gives it a serious competetion!!! The good news is that when a 1500 lumens led does come out(it will be easy to upgrade while the tk75 will not be) il updgrade this thing and once it gives 4000 lumens and throws 900 meters il say then only will it justify the weight and size of this thing .
@ slewfish -I use 3 keep power 3400mah on my BTU.so battery isnt a factor.There probably was a increase .i have no measurement tools. but to the naked eye there was no diffrence when i compared it to the tk75 when using the DRY driver, which was disappointing . The original digital driver performs flowlessly.
