Diving with TK35

LED Flashlights – General Info 18650 Flashlights
1

Just letting you guys know that a TK35 is able to go down to 16.6 meters (54,5 ft) without any problems (my dive spot wasn't deeper so I'll have to go somewhere else next time to test deeper...)

The light stayed on the selected output (I set it before I went down and didn't fidle with the buttons). Next time I'll try +20 m to see if the clicky (mode selector especially because long push turns the tk35 into disco mode...not really what you would want under water ) starts acting strange

This experiment just made my tk35 a backup light in shallow waters

cheerzzzz

Pretty interesting that you can use it as a dive light!

3

I am pretty sure it can go deeper, it has a very nice construction. Just don't have only one flashlight with you. To be sure, you can try to put some silicone on the threads as well as on the buttons, to ensure that no water is going to get in.

Thats very impressive! Definitely wouldn't try that with any of my lights though. Too much of a wuss :D

5

My lights are all siliconed so that wear and tear is reduced to a minimum ;)

And the spot where I went down with my tk35 was a spot where a light is not really needed...It was just an experiment ;)

and yup...the first 8 meters were "toit in zzz-the pants". I thought that I would get the disco scene at ±6 meters, but hey...lights are made to be abused :D

Does it have a forward clickie or a reverse clickie? If it is a reverse clickie I would expect the water pressure to soon turn off the light.

If it has a forward clickie it makes a bit more sense although you wouldn't be able to turn it off underwater.

7

Reverse clickie :)

8

I just read the Fenix site and it seemed to suggest it was a forward clickie. If it is a reverse it must have a strong spring. I can't imagine it's going to stay on much deeper.

9

it's a forward clicie, so on/off is not the problem, it's the mode selector clickie that will be the problem (as I explained earlier).

Now we just have to find that dept that turns the light into disco mode...wonder what my buddy will think when that happens :D

10

It will be interesting for sure. I think the button will leak at a certain depth however regarding the disco light (mode button) it depends on how that works. If that is a forward switch as well then as depth slowly increases it should slowly cycle through the modes toward the disco mode.

It the mode switch reacts more like a reverse switch it will probably just stay in the mode you put it in on the surface.

Let us know how it all works out. I'd be curious as to the front lens thickness and the design of the o-ring groove.

This light doesn't have a magnetic switch by any chance does it?

Anyway, keep those dive reports coming :)

11

The mode button reacts as a forward clickie too, but a long push makes the tk35 go into disco. so when max depth is reached, the light won't cycle, but it will go straight into disco mode...

no magnetic switch as far as I know.

Next week I'll try to go down to disco depth :Sp: :party:

12

My bad. Posting too early in the morning will have that effect. :)

13

Took the light 3 times down today...

Again no problems :D

max depth today was 21.1 meter (69,2 ft)

"automatic on" is at 5.5 meters (18 ft)

14

Nice! Good feedback on the activation pressure as well.

15

today was a good day for diving...

New info/data: 90.9ft or 27.7m is again no problem...

Had 1 little problem: I accidently touched the mode button at that dept and we went straight to disco mode so I had to stow the light away to be at ease. This dept is no problem but just keep clear of the buttons!

I didn't carefully watch when I was able to use the mode button again but 4m was okay so I suspect it to be in the same range as the on/off button to move freely.

I think we can assume that the tk35 is a nice light, and diveproof for recreational diving (90ft is pretty deep for recreational...60ft is assumed to be recreational here) if you don't push buttons at depth. Hi is a nice mode that gives plenty of light and a burntime that will outlast 3 dives if the li-ion's are 2500mah or more.

You will need to change the bolts at the tail of the light to bolts from the inside of a harddisk (torx and ss so no more rust)

There has been made a video of me today with the light but you'll have to wait a bit for me to put it on the www and post it here... Cheers

Nice report. 100 ft is an average depth for recreational diving in my area...it gets much deeper fast.

It's good to hear that the tailcap switch can handle that depth without leaking.

By the way, I just read where someone tried diving with the TK70 but it flooded after 15 minutes.

17

Well, here in my area's (non tropical and low viz (today was pretty good with 4m / 13ft of viz)) you've got to have 3 stars minimum to go deeper than 30m / 98ft and even then the +40m / +130ft is a depth that not a lot of divers are willing to go to.

Remember that here, in Belgium / The Netherlands, we have a lot of current in the "Oosterschelde" (Zeeland) so the dive spots are not the easiest ones, this in combination with the low viz could turn lots of tropical divers into a "oh-oooooh / no-go / panic mode"

good to know that the tk70 went blub blub :D hope that doesn't happen with me tough. does the guy know where the leak started?

I'm in the PNW (Seattle) so no tropical diving here either. It's limited viz and cold.

Regarding the TK70, there wasn't much information other than it leaked 15 minutes into the dive. I don't know much about the TK70 but my guess would be a leak from the tailcap area would be the most likely but I really don't know.

Haha...ok then ;-)

They make lots of fuss here about depths more then 98ft / 30m... Those Europeans...strange people we are
