I finally got my Swaro STC spotter in and tried out. I have been using a Kowa TSN-554 for several years. A few nights back my buddy I hunt with and I got a chance to compare them off my tripod.

This is no scientific review with charts, just sharing our opinions after trying them out at the same time. We were looking at a brick upright silo I've ranged at 750 yards and some cow/calf pairs grazing at 1.13 miles according to OnX. The tripod we used was my Slik 634 with the Outdoorsman's micro pan head.

The first thing that jumps out about the Swaro is the increased field of view. Between that and the eye relief being less finicky, the Swaro was just easier to use to find the cows, and easier to track them in as they grazed on higher power. This is a spotter I can see using to locate game, not just to evaluate it more than I ever did with the Kowa.

The Kowa's only real optical advantage I think after this test is the micro adjust focus. It's a little easier to get the perfect picture than the Swaro's barrel focus. Both are very clear once properly focused.

We both saw slightly more mirage with the Kowa too for some reason. I'm not sure why that would be different, but it seemed the waves from the atmosphere were more noticeable in the Kowa especially on higher power. This may be nothing, but it's something we noticed.

With the Swaro and Kowa both I could tell if a cow had a tight bag at that distance from not being nursed in a while. That's pretty good detail from a small spotter at that distance. I know my old ED50 wouldn't have shown me that.

I definitely like the Swaro better and will be selling my Kowa sometime this summer. I want to look through both a few more times and will update this if I find out anything new.

To me these are both great spotters. I've typically stayed with a compact spotter for the weight savings to help convince myself to take my 15x Swaro binos when hunting deer.

The Kowa is a little lighter and still very good optically. I've been very happy with it. I typically glass with binos off my tripod (Leica Geovid 10x42 HD-B or Swaro 15's) to locate game. If I want more detail I then switch to the spotter. For that type of use the Kowa has served me very well.
My decision to go to the Swaro was primarily wanting the extra field of view for when I want to save the weight of the 15's but still want more than just my 10's finding game. I also got a heck of a deal on my STC and couldn't pass it up. It does not give up anything to the Kowa except a few ounces of weight. I can stay on the Swaro scope longer without needing to take a break than the Kowa due to the eyepiece. The Ollin phone attachment I got for my Swaro is excellent too.

For anyone choosing between these two, my advice is decide if you locate game with the spotter enough to justify the cost of the Swaro. It is a more comfortable viewing experience with the less finicky eyepiece, and field of view advantage. If you just need the spotter to evaluate game already spotted, the Kowa does just as well for significantly less money.

Hope this helps anyone still on the fence.

As someone who’s has both I still have the STC. Agree with everything above. Great little scope that will always be in my bag.

I was between the two recently and was seriously considering the Kowa 554 before I learned they upped the price on them to $2k. Could've bought used of course, but being so close in price to the STC new I dove into a bunch of reviews. I was pretty sold on the STC and, after talking to Cody with GoHunt more about it, took the leap. Seriously impressed with it. Haven't felt underpowered yet and have made a few spots on deer, elk and bear at 3-4 miles.

Hunting partner is looking at an ATS because he wants more magnification...worried he won't be able to count points capped at 40x. Excited for this summer to see just how far I can effectively count points. I'm betting close to 2 miles, especially with digiscoping.

I compared my TSN-554 to my buddy's STC. The STC has the better FOV, but that's about it. Thats a non issue for me, since I scan with my binos and pull the spotter only for a better look. We both agreed the Kowa has better image quality. And the Kowa focus is far superior to the Swaro barrel focus, which knocked the image off everytime we adjusted it (very annoying). Both are very good optics, but I'll stick with the Kowa. Buddy fell for the new STC drop/hype and Swaro name. Wishes now that he hadnt.

That's good to hear.

I switched from 12x50 binos and mostly use 8x32s now specifically for the FOV advantage.

Spotter is just to look at already located animals...sounds like I'd gain nothing with the Swaro

Concur. In my assessment the FOV and touchy eye relief is a deal breaker.

I actually reached out to Kowa when reviewing one of their bigger scopes about the 55 series commenting on the shortcomings. The rep made a good point, they were the first with an alpha mini spotter and at the time it was the best (for like 6 years too). I think the market has caught up and they will likely come out with a newer one.

I agree center picture with good placement it is great glass though and I prefer its focus mechanism too.

I’ve pasted this a few places now, but a group of local Colorado folk got together earlier this year and as objectively as we could compared. Results at that event with the 2 samples we had were fairly unanimous.

That didn’t take long ;). If it’s close to swaro will be a sweet option. Specs are basically identical. Wish it published eye relief (edit: I see it now 17mm vs swaro 20), but the dual focus will be great.

We'll have a comparison video posted soon!

Oh, no!!!! Man, I can already see this costing me money.

My 554 has been spectacular for the 5-6 years that I've owned it. Going to have to watch for the reviews over the next year or so, and see if I can get my hands on one to critique for myself. The addition of the TE11WZ should be huge. Though it comes at a 6.5 oz premium, I could live with that. I do wish it wasn't integral, and could be removed, like the larger models in the line.

I didn’t realize this. That kind of bums me out. I was thinking this with the extender would have been a sweet little back country setup. Put the extender on when you really need it but not need to leave it in all the time for that little extra reach when conditions were just right.

Good to know, FOV can be a game changer for sure just depending on your use case.

Side by side with an stc and 554, I prefer the form factor of the stc, more compact... except i dont care for the OB lense cap... recessed as it is, it's cumbersome to grab with cold gloved fingers. I much prefer the lense cap on the 554. The increased FOV with the STC is a gamechanger though. Nearly as wide and bright as my Meopta 15x56 binos. Eye relief is also far easier to get behind with the stc.
