These are the results of my sample, unfiltered and unaltered. IS claims this is a defect and should have been sealed, and will ensure units will be properly sealed. Please subscribe if you appreciated this video. More to come.

[@calholli]

I'd like to see you completely take this thing apart and show how it's built.. Flush all the water out, clean the lens and try a DIY reseal for everything. That would make for a great video and show what's inside these things and where all the leak problem areas are from the inside.

[@4MRRanch]

I’ll probably do something along those lines

Would be easy to take it apart and put potting compound on the board to prevent water intrusion

[@qinarizonaful]

The procedure for protecting the electronics from moisture AND vibration is "potting" with electronics epoxy. There are many reviews on youtube how to take units apart, what to coat, and not to coat. If you don't need > ip68, to Navy Seal at 66ft, you can use a syringe to inject silicone gel/lube in all screw holes, into dead space in the housing, but I would avoid the lasers and lenses, and try to seal the housing and interior panels around them. Nonconductive putty used in water/insect proofing electrical boxes in construction would be excellent. 1. Pot all electronics and wires to prevent vibration/recoil shorts and wear and broken circuits/solder joints. 2. Use nonconducive electricians putty to fill voids and bulkheads and where wires pass through bulkheads and where wires are soldered/around lasers, in case you have to desolder/fix a part in the future. 3. Use silicone sealant on all batteries, movable switches, gaskets and rubber seals/screw holes (NOT Epoxy). (I do silicone this to all my flashlights/electronics AND coat the batteries and springs/contacts/voids ... I guarantee you that you will NOT have battery acid damage WHEN any battery leaks). I believe the unit would survive 30 min immersion up to three feet, = ip67, if this procedure was followed. Yes, I'm an engineer. If I have time, I may buy one and post a video, if anyone in interested.🎉🎉🎉❤❤❤ to all!

[@Ripper13F1V]

[@Scruffy-LookingNerfHerder]

The rain is a real concern for me. I did Moons Out Goons Out this year and we got rained on a bunch the first night.

[@4MRRanch]

Yeah, I would say this is a pretty valid con to this unit. I think the targeted way I poured direct water is a lot more severe than rainfall.

San Antonio here. Much appreciate these videos. have been thinking of a budget alternative as I was looking at the holosun iris but that could be another year before there's any news on that. As some one who's just getting into NV this seems like a reasonable option

[@4MRRanch]

San Antonio bros unite! Lol This is the best option for $500 or less (GL4 really competing though and saving you $200). The downfall of invisiblesight is the lead time.

[@ThatGuy3714]

For a $500 unit this thing performs extremely well. Now I wanna know how well that $1000 unit they sell is. I think im gonna pick one up next time they are back in stock

[@StayProteus]

I think the new move for the LAM market is for companies to start selling the parts individually and/or as a kit and provide a STL file (3d model) of the housing then for people to 3d print their housing with a resin 3d printer. 3d printing has a large learning curve however the hardest part is learning 3d design (CAD software, I think you said you’re a engineer so I’m sure you’re familiar) you can buy a resin printer that would be plenty good enough for that job for less than $300 and the resin technically could be as low as $30 but even for the strongest stuff would be less than $100. You could also just pay someone to CNC mill it or to use a DMLS 3d printer to print it out of metal (those machines are in the tens of thousands) and then you could assemble it yourself that way it would be a loophole since laser diodes themselves are not restricted and you can 100w (not MW) IR lasers for metal engraving online. I get the whole technology is different I’m just using as an example but anyway I think that route or a variation of it is the best for the LAM market

[@choke666]

I bought the Somogear peq15 for shits and giggles.. i mean, it works... It would break in a heartbeat if dropped wrong tho. It feels really wrong putting it on an MCX SPEAR though.. Very cool video bro. Well worth my time.

The somo is a good stand in until you can swing something better. I’d rather have the somo than no IR capabilities

Excellent video! I wouldn't be terribly surprised if those shifts were due to the whole rail shifting, even though it is a good one. I'd be curious to see what happens if you mount it directly to the upper and then drop it on the unit.

[@4MRRanch]

Not a bad idea. If I revisit this, I’ll mount to the upper

[@Annoyingdog37]

my somo had a similar failure in the rain, im sure the water got in through the top from under the fire button however the front laser lens fell off from within and was rattling around. I have basically disassembled somo ngal now and the springs used are quite impressive.

[@4MRRanch]

I’ve seen the internals of the somo. Honestly a well built unit, besides the water sealing

[@MedicalTape_xX]

back when you did your first video on the Somogear I asked if you be able to water test it and you pointed out that you had to buy these your self so no, totally fair. But ig something changed, any chance of seeing this test with a somo?

[@cleebster]

Seems like a good solution for waterproofing would be countersinking set screws into the holes and capping with with epoxy. Could still be undone by scraping the epoxy out although it would be annoying, and still allows you to move through all the options.

[@xDeVeYx]

i ordered a mk4 vscel version after watching your review.

I hope to be reviewing a mk4 soon. Currently waiting on mine.

[@poohyjs]

[@jalowery1246]

Again, such an impressive device. Is there somewhere we can find a video detailing this epoxy safeguarding procedure? With the massive qty of these devices sold im fairly certain there would be a substantial amount of owners interested in viewing this procedure (including myself of course 😆)

[@4MRRanch]

From what I understand, they drop a couple drops down each safety screw hole, then use the screw to seat the epoxy into the hole (remove the screw so you don’t lock it in)

[@TnTriton225]

1.What epoxy do they use or you suggest? 2.Drop epoxy in, screw down, then remove and let epoxy dry and then return screw, that correct?

[@whiskeyactual.]

I'm in SATX and can concur, the dirt is like concrete here when dry. The amount of water intake is concerning though, ngl. Hoping to receive my IS/EG relatively soon; ordered mid March of this year.

Is this one crane or LA23? He sent me LA23s for testing. I'm a bit concerned about immersion and internal sealing of the crane port. Crane definitely has more potential for water entry. I'll be sending him some suggestions along with my feedback after dumping a case of ammo through both units. How tight are your turrets, mine are kind of squishy while adjusting, but seem to be holding zero and not moving unassisted.

[@4MRRanch]

LA23. Some play in between adjustments, but not a whole lot. I go over this in more detail on my actual dedicated review. My intention in this video wasn’t to reiterate the performance I already covered other than in these test conditions. For $500 units, people shouldn’t expect $5k performance

[@carbon4201]

@@4MRRanch I'm fairly impressed so far. Immersion testing worries me a bit. Going to seal my screw holes, give it a bit to set and go shooting this afternoon.

[@punk8570]

Do you have any recommendations on running a Ir lam on a Remington 870 (Ik why would you do that right) but I’m thinking about getting a 870 as my first gun and I’ve been working on a night vision project for a very long time and wanna get into night time shooting for a long time. My only idea so far is designing a dual picatinny mount that are side by side and mounting it to a m lok pump. I was thinking about buying a holosun LE117ir and a surefire vamp clone for it when I do get into that.

[@4MRRanch]

I don’t suggest anything that’s unsuppressed for night shooting. Especially if you don’t have a place to shoot far away from neighbors, you’re going to annoy a lot of people. You’ll also produce a decent amount of flash and not be very stealthy visually, sound aside. I also don’t recommend a clone light on a 12 gauge. That said, the LE117 and surefire vampire combo is a good one. It’s probably worth the extra cost for the 221 series (I’d rather have an LS221 series than an LE117 if budget becomes a challenge ). Zeroing at night with an IR laser won’t be as accurate of a zero as you can do during the day.

[@punk8570]

unfortunately the biggest problem with these chinese knockoffs is consistency. I just cant trust that the one I buy will perform as well as this one.
