I've finally decided to spend some money on a good spotting scope, I don't even take my current spotting scope to the range anymore as my Sightron SIII does a better job than it. Max I am really wanting to spend is about $1500. The main use for it will be shooting at the range(spotting bullet holes) and occasionally being brought along for 1000yd shooting.
I have somewhat narrowed it down to the Kowa 82sv and the Pentax 80ed. The Pentax seems to stand out since it uses standard 1.25" eyepieces so there's a plethora of choices for that, even with reticle a which may be nice. The Kowa seems to use only Kowa eyepieces. On the other side from what I've been able to read the Kowa seems to have better glass as it appears as a favourite for F-class shooters based on being able to spot mirage very well. Now I'm not shooting competively yet so not sure that will matter. So really it's a toss up and I have no idea who to throw my money at. Feel free to offer other options as well that I may be overlooking.
As I have mentioned before, the use of a spotter kind of falls into 2 categories... seeing stuff and seeing mirage.
All F class shooters use their spotter to see the mirage. Our high mag scopes are plenty good to see the target and scoring markers and hole pasters and even small bugs on the target.
For mirage, I use the Kowa 82SV. It works and works very well. Any better then the Pentax? I think they are very similar. The Kowa was less money when I bought. When there is no mirage, the optics of this kowa is stunning even at very LR BUT once the air starts to get "dirty", the ability to see fine detail at distance drops fast. And that is the flip of the coin... for optics to see mirage well, the object image has to degrade. Forget about seeing bullet holes with either of these.
For that you need to enter the wonderfully expensive world of ED glass.... say double your budget. Here, you give up being able to see the air but the target remains far more clear and readable. If you were a sheep hunter, this is what you would want.
BUT can any of this see bullet holes beyond say 300yds? I would suggest you would have just as much luck with a quality rifle scope from Sightron, NF or March, S&B or tangent Theta vs a spotter. It is really really hard to see anything in the black... better if you drop the bullet into a white page BUT mirage and distance, this becomes iffy.
SO.... if you need to see the target at distance to know where you are hitting, get a LR camera system and just view the target on your IPad. The Caldwell system I am bringing in works very well and dirt cheap for what you get. Then regardless of weather and distance (suggest useable to a mile????), you will be able to see your target clearly like you are "6 ft away".... literally
If you are spotting with another shooter while LR shooting, I bet your sightron will do all you want and then some. You already have a comfy set up, great glass AND a ranging reticle so you can help call in adjustments easily.
Today, the spotter is really in limbo. Rifle optics have gotten so good that they are usually better then most spotters until you spend big bucks. The camera systems are head and shoulders better and easier when you need to see holes in target.
If you need to see game, better quality binos are so much easier to use. For those rare times when you need high mag to resolve the target at longer distances and don't want to 'aim' at it, you need to see through all weather between you and the target and that requires super pricey glass.
YMMV.
