The narrow beam vs the wide beam is posted as a picture in the review. The narrow beam didn't pop the balloon at any focus setting at 14'. The wide beam laser with focus can do it but you have to be steady holding it. A tripod or mounting would be good.
It is difficult to meaure beam size at close range. Anyone here want to go outside into sub zero temps to do so?

I put the 3x beam expander back on the Sky-200 and now it will pop a balloon like the Sky-150.

I'm thinking that the Sky-150 has some type of expander for its focusable feature. When I added my 3x expander to the Sky-200, it would do the POP balloon trick. Focus and stability are critical on both of these.
I posted a picture above of the expander.

why stability is critical? you just need a steady hand to to the pop trick :)..... have yoy tryed that is the MAX birning distance for matches? maybe it is 2... or 3 meter. that would be a NICE JOB MADE BY THE INTERNAL SEMI-EXPANDER.

ah...hemlock... you forgotted to say us the estimate Mrad of this laser. but ithink it is for sure lower than 0.8 mrad..... to pop a baloon at 4.6 meter... and it is only 200mw... not a powerfull handheld like 300...400mw...

Stability --- I meant holding the dot in a stable manner by hand :) It's hard to do at over a couple feet and I need to make mountings in order to POP or measure beam diameters.

I was one of the people that got the original SKY 200 in the GB it was good at first but now I would estimate less than 50mw . YMMV when dealing with them.

Merc --

The first batch was actually their second run -- I think DrLava and I were the only ones to see the first ones. The second run still had connection problems inside but I've cleaned mine and used antiox lube on threads etc. Mine actually warmed to 310 mW last night!! much of the time, it's between 85 and 180 mW.

As I have mentioned, I got a SkyLaser model P532F-150B-Fa for review.
Many of you know that DrLava and I purchased some of their first "prototype" lasers when they started building lasers for beta analysis purposes. This laser is a culmination of their gained experiences in the marketplace.
It arrived today at the USPS and I picket it up in person.

General Details:

The laser was well packaged including a hard shell case which included the laser, charger, keys and dongle. No 18650 cell was included because of shipping regulations.
The laser itself was double wrapped in antistatic bags and well protected.
This portable laser has a label indicating FDA approval and it has a front shutter, key switch and removeable rear dongle plug to disable the laser.

No instructions were included but, I guess, by now, we know how to install the cells in green lasers (I hope) ! Another nice feature is a 1/4-20 threaded mounting hole to affix the laser to a camera tripod... NICE. Be carefull not to go to deep or you can short to the cell connection. The threads appear limited to prevent this but be aware.

Mechanically, the housing appears much improved over the original product. Threads are cleaner and the overall appearance is better to the eye. My first ones were gold colored. It has a key switch feature plus the LED warning indicator but the "clicky" on/off button is rather high making it too easy to turn it on. If it rolls over on a table, it will turn on and stay on.
The front ring allows for manual focus which may be difficult for some here because it acts as a beam expander and the exit beam is rather large until it gets to its set focal range. Also, the beam exits about 4 degrees right of the axiz of the pointed direction but this is somewhat common of pointers and portables considering the crystal allignment requirements.

A quick update about Power because I know you are all interested in that. Of course, I can not tell if this is a "Hand Picked" laser for review.
My first graph shows stable power averaging 200 mW. This is at a 65 degree room temp. The second graph shows output after the laser was warmed to "body temp" -- not much difference.

I will be submitting photos and more updates here. Analyzing divergance might be a trick with this focusable assembly feature not found on many lasers.

Trying to measure divergence is a problem as I noted above. Using Goggles (provided by Steve from Wicked Lasers), and using a black carbon target, I measure 0.243" at 1 foot and 0.193" at 30 feet. I can't get greater range with the "blizzard" outside tonight.
I need a suggestion on how to measure divergence with this focuasble portable.
I tried to get a picture of the convergance but beam shots like this are difficult.

This is a side by side exit beam shot of the Sky 150 (L) and the older Sky 200 (R).
Note the large exit beam of the 150 vs the 200. Both are focusable. I will have to ask if this is normal.

Does anyone have any idea where I can find this to buy online? (if it's not to expensive) I've googled it, but found nothing strangely?!

:thanks:

I think it's like 800$ now.. I got mine for 250$ back before they decided to go and try to be a low quality laserglow-priced wannabe, now I doubt anyone but the government pay for their units... Kinda like their 500$ hammers. lol. :crackup:
