GSod, this has been a problem I have been investigating for a few years now.
So far, I have tried a Celestron 80 reg lense. Very clear image, surprisingly better then the money suggested. Bright, good colour and resolution BUT the mirage was not as clear as I wanted.
Mechanicals and eye relief worked very nicely. For a range spotter, great value. Plastic eye piece so care needed to avoid damage. Sold it.
Recently, Vortex Skyline. Not as clear as the Celestron but a bit better at seeing mirage. Worked well and smaller then the Celestron. More money but seemed to be a bit more robust in construction. Very good eye relief.
I used it in Alberta for a relay and found the mag too high. For a spotter at low mag, the field of view is what you expect BUT I found it hard to see as much of the range as I wanted. So I decided I wanted LOWER mag and wider field of view. Sold it.
Of all things, I got a Tasco cheapie from London drugs on a sale. The image was better then alot of more expensive spotters at low mag. Stunned BUT it was all plastic so would probably implode the first time it went into a range box. For S&G's, this was a surprise.
A few years back, I had a Pentax ED65 and stupid me, only stuck variables on it so wasn't as happy as I am sure the spotter could be. The image on this thing was really good and the smaller size desireable. If I had half a brain and just got better eyepieces, I would likely still have it. Sold it and the new owner reported being extremely happy.
Might go back to that...
The Pentax 80's are a great spotter no doubt but I am looking to spend way less money and maybe have a smaller unit.
This unit doesn't have to have the clearest image, I only want to be able to see the mirage.
I also think I want to have very low mag. I have a set of Nikon 12X50 binos that work really nicely for field spotting and mirage work. It sees the mirage really nicely. Huge field of view which would be fantastic to see as many flags as possible.
If I can rig up a mount to use it, I think I would be happy with something like this.
So I think I am on a quest for LOW mag, wide field of view that excells at seeing the air. Clarity not that important as I spot the scoring dot and value with my scope. Also, smaller size is a good thing as I already have enough stuff to cart around.
For a stand, I got a really nice unit from the US. RayVin - now retired I think. Robust, heavy so it can support a decent spotter without falling over. Easy to adjust. A very nice unit.
Love to hear your experiences on other units.
