Kowa Prominar "Glass" vs Swaro ATX/STX/BTX Modularity

After spending several years behind low quality Celestron glass, I decided to upgrade this past season to a pair of Razor UHD 10x42s. I also added my first spotter to the quiver with the new Razor 13-39x56. I'm primarily a backcountry archery elk hunter, so I didn't feel I needed a big spotter with the larger zoom. That said, I've also started getting into more glass intensive hunts so I can spend more time in the field each year. After most of a season behind the glass, its been undeniable their impact on my ability to find and identify game at distance. All that said, I'm admittedly a bit of a gear head, and find myself wanting to upgrade and further improve that glassing experience. I feel the UHDs and the mini Razor are suiting the way I'm currently using them well enough that the first upgrade, or maybe I should say addition, to my quiver that I'd like to make is a larger spotter. In the long term, I'd like to add to that quiver so I can choose the glass that best suits the hunt I'm on.

After all of my research, I've narrowed it down to (2) lines of spotters, the Swarovski ATX/STX/BTX line, and the new Kowa Prominar line of scopes. I feel I've read enough reviews/comparisons of the scopes to know the Kowa "glass" is subjectively better. I've never used dual focus wheels either, but they seem ideal for me in theory. The helical focus on my Vortex drives me nuts, which gives me a little pause in sinking a ton of $$ into alpha glass with it. On the other hand, the modularity of the Swarovski scopes is what I find intriguing, making it difficult to choose. In the time I've spent behind my current spotting scope, I find myself wishing I had bought the Razor with the straight model 50% of the time, while I'm glad I have the angled model the other 50% of the time. The ability to purchase both the ATX and STX with a single objective lens to have that flexibility in the long term would be a plus in my mind. On the flip side, I could just purchase the body of a second Kowa scope for less than an ATX or STX, depending on the objective lens size. Where the dilemma really comes in is the ability to add the BTX to the lineup. I think its hard to argue that glassing with (1) eye at 20x on a spotter is better than glassing with (2) eyes at 10x with a pair of binos. The same would logically apply to the BTX at 30x vs a typical spotter at 60x. But, I'm not sure how often I'd use it considering the size and weight.

For those of you out there with Alpha glass, what did you do, or what would you do if you could do it again? Is the flexibility and possibility of adding the BTX to the quiver enough to go with Swaro? Or would you go with a couple Kowa bodies in the long term and call it a day?

I did all the same research and time in field as you and I ended up buying the Kowa 884 (straight). I felt based on reviews you are splitting hairs on overall image quality of the 2. I would not trade my Kowa for a BTX just for the fact that it’s extra weight and bulk to me. I’ve glassed behind sub alpha glass with Zeiss and Vanguard. I would get a great deal of eye fatigue with both scopes. The Kowa does not give that problem, also I wear an eyepatch which to me makes a big difference. I can spend hours behind it and have no problems. The duel focus is the best focus wheel u can have it makes a world of difference. IMO I will never replace the Kowa, I am going buy the 554 for lightweight backpacking hunts. I do not have anything against Swarovski. I may have bought the BTX if I could afford it but dollar for dollar it’s tough to beat a Kowa. I hope this helps and wish u luck on deciding. If u have any other questions about the Kowa PM me and I’ll answer it best I can

I like the eye patch idea. Never thought of that.

Kinda makes me think that a pair of 15X SLCs or 18X UHDs would be the much more economical choice if I really wanted to glass with both eyes and more zoom. Not to mention the packability if I was on a backcountry hunt. Any experience with the higher zoom binos or have you not found the need for them?

I really wanted a Swaro 65, but listened to the research and bought the Kowa 66. I wish I had bought the Swaro. Try to test them out for yourself and don’t let others sway you.

Any particular reason why you wish you had gone with the Swaro instead?

I've honestly been leaning towards the Kowa, but all these hypothetical uses has the Swaro sticking in the back of my mind. Haven't looked through either though honestly. Haven't seen the need since I don't have any place locally to do that (no Kowa around) to my knowledge.

Might be worth trying to find a forum member with a kowa near you to at least look through.

Love my kowa 774.
