I'm selling a Retra LSD snoot with the matching adapter for Seacam 150D strobes. As the original owner, I used the snoot for years and it always worked perfectly (what could possibly go wrong with it?). It has a few minor signs of wear and the front lens has a couple of tiny scratches, but these don't affect the light transmission in any way. The buyer will also receive 6 different mask sets for various diameters and shapes of the light exit opening, as well as a spare parts kit, 3 additional diffuser discs, and the original silicone lubricant. Insured shipping from Germany is possible upon reimbursement of costs. 220,-€ As this is a private sale, the item is sold without any warranty or guarantee. Liability for damages resulting from injury to health, body, or life, and for gross negligence and/or willful misconduct on my part as the seller, remains unaffected.

Thanks, very helpful! I think I'll go with the XTARs, since they're definitely recommended by Backscatter and are significantly cheaper than the NiteCores. And whether the NL2160HP actually has 6000 mAh and thus a significant advantage over the XTAR, I can't even verify.

My question concerns the principle of how many amperes the HF-1 requires at a minimum. Backscatter surely provides specifications for this, which I would like to know. There are plenty of other batteries with the same capacity of at least 5000mAh on the market.

Thanks, good ton know! Very helpful, thanks! Because of the strange answer, I asked again how many amps the batteries for the HF-1 must have at a minimum, but I haven't received an answer yet.

I also find this statement somewhat strange and will decide either for the (very expensive) Nitecore or the (significantly cheaper) XTAR anyway.

I posted 2 links -the first led to the Backscatter page and the second showed the other battery model with only 10A. But: Backscatter claims that the amperage doesn't matter (see my quote in my last post): 'The batteries we sell have been tested and work properly with our lights. The NiteCore and the Xtar work fine the different amps have no real issue with the lights.' However, I also find the word 'lights' somewhat strangely chosen in this context.

Just to mention it... Backscatter replied to me with the following: 'The batteries we sell have been tested and work properly with our lights. The NiteCore and the Xtar work fine the different amps have no real issue with the lights.'

Thanks! May I ask, if you're using the NL2160HP with 20A, or the NL2160 with 8A? Thanks for the Link! May I ask, which strobes you are using this batteries in? This appears to be the same battery I linked to in my first post: https://www.backscatter.com/Xtar-Dual-21700-5000mAh-Rechargeable-Li-Ion-Batteries However, on the site you linked, they cost only a fraction of the price compared to buying directly from Backscatter. Interestingly, XTAR offers a slightly more expensive version with 6000mAh, but only with 10A: https://www.akkuteile.de/en/lithium-ionen-battery/protected/size-21700/xtar-21700-5000mah-3-6v-3-7v-li-ion-battery-electronically-protected_100839_3404 So if someone is successfully using the Nitecore version NL2160 with 8A in the HF-1, this version would probably also work. I'm still waiting for Backscatter to answer my questions... Btw: I just received information from a Nitecore employee that the model NL2160HPI is only suitable for specific Nitecore flashlight models. So, don't buy it for underwater strobes!

Because the batteries will be used in the HF-1, I was writing an email to Backscatter for a recommendation. Hope to get their answer soon. Someone here on the forum has mentioned that only the Nitecore work with the HF-1 but this was some time ago and I can't find it back. This has certainly changed by now, otherwise Backscatter wouldn't sell any other batteries for the HF-1. Indeed, very interesting.

Thanks for your opinion! I've already ordered the Nitecore UMS4 charger, which of course can handle the size of the Nitecore batteries.

Have you had any experience with different 21700 batteries in strobes? I'm about to buy some and I'm currently searching the internet for the best batteries suitable for it. Initially, it was said that only Nitecore would be an option for the HF-1 Backscatter. Furthermore, there seem to be models with slightly different sizes, and I don't know if the HF-1 can cope with these size differences. Nitecore now offers several models of the 21700, which differ in capacity and ampere: Nitecore.de21700 Li-Ion Akkus I would definitely prefer a model with 6000 mAh, but there are already three different models within that range: Just 8A: https://www.nitecore.de/nitecore-li-ion-akku-21700-6000mah-nl2160/nc-nl2160 20A: https://www.nitecore.de/nitecore-li-ion-akku-21700-6000mah-nl2160hp/nc-nl2160hp 20A with a special feature of a positive and negative terminal on both sides: https://www.nitecore.de/nitecore-li-ion-akku-21700-6000mah-nl2160hpi/nc-nl2160hpi But does that mean the latter is a different size? I'll probably contact Nitecore and ask. Backscatter now has a recommendation for this battery type on its own website: https://www.backscatter.com/Xtar-Dual-21700-5000mAh-Rechargeable-Li-Ion-Batteries Low capacity, but very high ampere. I'm confused... Furthermore, my dealer recommended the following battery to me - of course, because he's selling it himself 😁: https://www.uwcamerastore.com/xtar-21700hp-5000mah-25a-battery Relatively cheap, low capacity and no information on the ampere. Ergo: do you have any recommendations, advice, or tips? Since I'll be buying at least six batteries, this is going to be quite expensive, and I'd rather invest a few more €s in good batteries than make a bad purchase. Thanks in advance!

I'm selling a high-quality underwater spiral strobe cable for Sea&Sea strobes with an S6 connector. The cable has been used for fewer than 10 dives and is in very good condition. Insured shipping from Germany is possible upon reimbursement of costs. 50,- €

Could you please post a link?

I'm not familiar with the Wolfbox blower, but I've been using the Nitecore BB21 for several years now and I'm very happy with it: https://www.nitecore.com/product/bb21 It's definitely a good gadget for removing water and dust, and certainly much more powerful than a manual blower.

Hello, I'm selling a completely unused Retra LSD adapter for the Sea&Sea 110 alpha strobe. It's been sitting in my closet for years and I sold my Sea&Sea 110 alpha strobes a while ago. It's fully functional, but it has a few minor scratches from being stored with other underwater photography gear, which are barely noticeable. Insured shipping from Germany is possible upon reimbursement of costs. 40,- € As this is a private sale, the item is sold without any warranty or guarantee. Liability for damages resulting from injury to health, body, or life, and for gross negligence and/or willful misconduct on my part as the seller, remains unaffected.
