Hi Gabe/went to your two sites and actually managed to find (with your help) both items. Think I may even have found someone to do the solder work. Made a note of the safety glasses also. Final question: what batteries and charger do I need? Am I to assume that the "host" at Survival Laser...

Hi Gabe/ was out of town again; sorry for the long pause. The following terms are Greek to me: diode, host bundle, heatsink. There, my true confession; I can manage a light switch or get a plug in a wall..........that is about it. I will call around to see if anyone knows/has equipment to solder...

Hi Gabe/ I'm back now; looking forward to hearing from you about your newest green laser/Chaz

Hi Gabe/ unclear about the quoted op temp; are they like a switch.......below 10C they just stop working.........or are they slower to turn on..............or beam not as "strong"??? Remember I am the newbee. Don't know who "Gray" is, so Cannot email him questions, let alone don't have an email...

Hi Gabe/ just looked at the stats for the 300mW Laserjet you suggested; I need outdoor op temp range from 0C to 30C & it seems that the PLE-PRO 300 is 15-35, so its' lower op temp limit is 59C; that is a no-go. With the beam expander the price tag is $389............wowzer! A little steep! The...

Hi Gabe......thanks so much for your guidance. Just got back from vacation-family reunion so I have not acted on your lead. Just unpacked. Promise to do so Sunday and will probably make the purchase Monday. Will provide feedback to you. Again, thanks for helping a rank newbee/Chaz

An addendum/ this needs to be manufactured/shipped by a company that is FDA compliant. US Customs/FDA has a list, by country, of those companies that are not. Customs then holds/destroys shipments without ever inspecting them........as I understand it. When I checked the list a few days ago...

Hi joeybab3 and Gabe/ yes, I just need the visible spot. Daylight use only. Several of us need then to line up six (6)poles (diameter about 3/4 inch) that we will stick in the ground. Will place the laser on a bench, then walk downrange placing the poles at intervals out to 200 yards. Laser will...

Still struggling to find a 520-532 green laser that will project a small daylight visible beam out to 150-200 meters, function in 0-30C temps, is IR filtered, uses rechargeable batteries, has a constant on/off switch, and meets FDA requirements. If I need to pay more for a lens to focus the...

Hi Gabe/ thanks for the idea of stepping up the mW; I have no knowledge of lasers, just the function I want to achieve. You mention 300mW; what can I achieve if I step down to around 175 mW; will I still achieve my goal of a "small" visible beam spot in daylight hours? And YES, I will need a...

I will discontinue this thread and stick to general; didn't know two threads were a no-no; sorry/Chaz

Gabe & joeybab3/do not know what a 301 is.........is it like a 520? again, I admit I am lost at sea. Would I have better luck if I tried to find a 520 nm laser? I just want a beam spot I can see in daylight at 150 to 200 meters. Would a 175 mW be visible in daylight? I am just interested in the...

Hi Gabe/ thanks for trying to educate me in a way I can (sort of) grasp. Appreciate that. Am I at least in the ball park thinking that a 200mW would get a good visible beam spot? What if I shortened my working distance to 150 meters? It sounds like I would have to rig up myself something to...

Gabe/ I researched the HL532 200 mW. They show it to have a beam diameter of 2.1mrad, a divergence of 1.2mrad. I wouldn't know a mrad if it bit me on the leg. True humble confession. The op temp is listed at 10-30C. We would be using them from 30F to 85F. I joined your website & posted this...

Thanks for all your responses; please understand that electronics beyond a light switch on the wall is a challenge for me. I would be placing the laser on a bench, then using the beamed spot to line up six poles (paced in the ground) in the ground out to a distance of 200 meters. Stick the...

My newbe searches online don't "point" me to what I need to buy; it is use specific and the criterion are: 1.Green 532 200 mW laser pointer 2.22mm or smaller diameter body 3.constant off/on switch 4.working temp from 0 to 30C 5.duty cycle of 120 seconds /30 seconds or better 6.IR filter/shield...
