SmartPin Extra: S&B + EEC

posted in: Scope Add-ons | 0

This is a special version of the SmartPin Pointer, designed for my Schmidt&Bender scope. As we know, this scope model suffers from an extremely big temperature shift issue, every 10°C temperature change results 4.5 yards misranging on a 55 yds target! This means 8.5 mm shift on the standard S&B sidewheel.

I spent years with testing my Schmidt&Bender scopes from the hardest winter to the hottest summer, so I can make a precisely calibrated sidewheel strip for any difference. Recently, I’m using a 10°C scale with my SmartPin pointer and it works really fine, but I decided to design an Extra version for myself, which is calibrated to my Schmidt&Bender FT scope and has got some other extras, too.

I changed the scale so the distance between two main marks is 8.5 mm ( = 10°C on the S&B scope ), and this scale is on a removable plate, with another scale on the other side. The other scale is shifted by 4.25 mm ( = 5°C). This means, that I can use any sidewheel strip, calibrated to 0, 10 or 20, or -5, 5 or 15 degrees, the scale on the pointer will always fit to it, and the big marks show 0, 10, 20 etc. and every small mark means exactly 2 degrees. The scale covers 24 degrees, i.e. if the sidewheel strip is calibrated to 20°C, you can use the scope between 8°C and 32°C.

Because the illuminated reticle doesn’t leave enough space for a separate EagleEye Clicks Magnifier, I combined it with the pointer. Also this one will be a special version, with an acrylic lens instead of the standard Fresnel type lens.

Two of this pointer are being printed already, I’ll use one and the other one might be for sale.

The other one can be ordered here: SmartPin Extra S&B + EEC. If you buy also an EagleEye Parallax Magnifier, to make the order complete, you can get £5 off the total by using coupon code EAGLE-SMART at checkout.
