Kowa TSE-17HD overview

  • 1Description

If you need to wear eyeglasses when using your Kowa spotting scope, you'll appreciate the long eye relief of the TSE-17HD Eyepiece. At 32mm – well over a full inch – this optic allows you to stay well back of the eyepiece and still see the full field of view. The long eye relief also provides plenty of flexibility when digiscoping. Designed for use with Kowa 60mm, 66mm, and 82mm spotting scopes, the TSE-17HD delivers magnification of 25x, 25x, and 27x, respectively. The apparent angle of view for the 60mm and 66mm scopes is 52.5°, yielding a linear view of 110' at 1000 yards; on the 82mm scope, the field is 105'.

    Kowa TSE-17HD reviews

    TSE-17HD 25x Long Eye Relief Spotting Scope Eyepiece is rated 4.9 out of 5 by 10.
    Rated 4 out of 5 by from Makes extended veiwing time much more relaxing. This lens does exactly what the name implies. It gets your eye further away from the eye piece lens. This makes viewing much easier without eye strain. On my 60mm Objective lens spotting scope the field of view was not too restricted. There is a tall rubber eye cup that places the eye at the proper 30mm distance from the eye piece lens.

    Rated 5 out of 5 by from TSE-17HD 25x LER I'm using the 25xLER on a TSN-82sv for HP rifle competition. 25x is good for XTC, you might want the 20-60x for other applications. Kowa makes a good product.

    Rated 5 out of 5 by from Purchased after researching spotting scopes extensively We shoot 500 to 1000 yards, and our cheap old spotting scope broke inside, so we read reviews, forums, customer product reviews for a few weeks. We chose this Kowa 25X long eye relief eyepiece and TSN-82SV 3.2/82mm Spotting Scope on all that, and we are just delighted. We could have spent 2-4 times as much for a high end brand, but we were looking for good benefit for the cost.

    Rated 5 out of 5 by from Excellent piece of optics equipment Excellent piece of equipment, which I use for high power rifle competition. i can actually make out 223 sized impact holes at 300 yards (if there are not too many previous impact pasters already on the target). I used this eypiece on the Kowa TSN-601 spotting scope body. Very happy with this purchase and upgrade to my equipment for rifle competition and hunting.

    Rated 5 out of 5 by from Best Quality I knew exactly the lens I needed and - as usual - B&H had the best price. That has consistently been my experience with this company and the one time (long ago) I had to contact Customer Service they were quick and efficient. A real pleasure to do business with these folks.
    Date published: 2017-10-16
    Rated 5 out of 5 by from Excellent eye relief The LER eyepiece gives me a great view without having to remove my safety glasses or sunglasses. I had removed the rubber eyecup to get the clearance for my glasses. I added the clear lense cover to see through and protect the eyepiece.
    Date published: 2017-07-25
    Rated 5 out of 5 by from Excellent choice for glasses wearers I wear corrective lenses and purchased this to use on a TSN-82SV on the advice of a glasses-wearing friend who has the same eyepiece. This eyepiece is very comfortable to use and an image at 200 yards is quite sharp and bright.
