deadeye ive Posted December 17, 2007 Report Share Posted December 17, 2007 As its name implies, this scope was designed primarily for American hunters. Unlike European-style scopes, which have first focal plain reticles and 30mm main tubes, the American Hunter has a second focal plane reticle and a one-inch main tube. Ok peeps .........Can somebody put this into layman's terms for me .I'm interested to know the main advantage if any and does the second focal plain mean a change in cross air thickness when zoomed in or out ?

tulkyuk Posted December 17, 2007 Report Share Posted December 17, 2007 30mm tube = better light trassmission 1st focal plane = cross hairs get bigger as you zoom 2nd focal plane = cross hairs stay same size as you zoom best scope would be one with 30mm tube and second focal plane = for longer range stuff Quote Link to comment Share on other sites More sharing options...

JohnGalway Posted December 17, 2007 Report Share Posted December 17, 2007 I'd agree with Tulky, maybe it's a gimmick, maybe not but it's 5mm more gimmick than I'd have gotten with a 25mm tube Quote Link to comment Share on other sites More sharing options...

" Ive, you may have a point there! If you read the Leupold brochure they don't claim better light transmission- "30mm maintube with increased elevation and windage adjustments" It gives more room for the mechanism to move so you can have around 90 MOA adjustment, but the 1 inch tubes of the same scopes have around 50 MOA. Not a big deal for most people, but if you shoot out to very long range it may be useful. Quote Link to comment Share on other sites More sharing options...

Dunkield Posted December 19, 2007 Report Share Posted December 19, 2007 The 30mm tube thing seems to be driven by us, 'us' as in Europeans. 'We' also got Leupold into making 50mm objective lens scopes as well, where as before they were happy with 40mm for the home market. They don't shoot at night in the US and they generally have more light than us (generalisation I know) IMHO they may have fealt they were loosing ground to European manufacturers and made the decision to do something about it. Although I own a couple of 30mm tubed scopes I have never tested them back to back against 25mm, I would have thought the light gathering difference would be minimal, if there is any at all.

Alycidon Posted December 19, 2007 Report Share Posted December 19, 2007 Forget tube size. my 25mm Ziess outperforms my 30mm Swaro in low light. Only real benifit is slightly more adjustment range for the bigger tube. Buy it once, therefore buy quality glass. A used Ziess is far better value than a new American scope, theres a little 4x32 in McClouds of Tain at present for £175, you wont get better value than that.

A Sick Old Man Posted December 20, 2007 Report Share Posted December 20, 2007 I have heard bad things about these US Zeiss, I called Zeiss UK and was having a chat with there Rep, he said that there is a great deal of difference in lens quality between models. You can not go wrong with any VICTORY line, just look at the difference in prices between the ranges. Quote Link to comment Share on other sites More sharing options...

I'm surprised by that comment from the Rep .Afterall in this day and age the brand name ,or has in this case ZEISS has to be protected and never devalued at all cost .Is he a personnel friend ? Going off track a little ............Regarding scope quality I have a 8 x 56 Schmidt and in poor light conditions (No lamp either) I compared my Webley Platinum 4 x 12 x 50 against it and to my surprise the clarity was equally as good .However I have never accidently dropped ,banged or smacked this scope as I know it would be scrap .The schmidt however would withstand a lot harder impact and IMO this is where some of that additonal money is spent .

A Sick Old Man Posted December 23, 2007 Report Share Posted December 23, 2007 He is not a personal friend, he was just explaining the difference in quality between Zeiss products. I think they are all pretty good, just Victory stuff is the dogs nads Quote Link to comment Share on other sites More sharing options...
