I have a tenpoint flex...it can be adjusted for the following:

175 fps
265 fps
305 fps

Is there a crossbow scope that can be adjusted to accomodate these three settings or do you need to get different scopes...the reason I ask is that most scopes say something like "for crossbows shooting between 275-300 fps"

Cossack

The only (scopes) you can "adjust'' to accommodate are the LumiZone VariZone scopes marketed by Excalibur. They are good but a bit on the heavy side, esp the Lumi. If you're looking for a scope alternative check out the Hawke Crossbow scopes. Been reading a lot of positive things about them. If you're willing to settle for a non-magnifyong alternative, check out the 4 dot Crossbow Reflex Sight made by TruGlo. It has 4 sets of 4 dots that are different distances apart, one can select the set that most closely matches arrow speed. It's small, weighing only a couple of ounces, and has red or green dots to select from.

awshucks

The 'Zones Cossack mentioned only compensate between 250 and 350 fps. The Hawke doesn't compensate at all like any fixed reticule models, but rather has some kind of computer program that will tell you what ranges the other than 20 yd aim points will be on at.

Moonkryket is/has been doing some tests on the Hawkee, but I lost interest when I found out it doesn't compensate for even numbered ranges like 30,40,50.

Wyvern Crossbow

Truglo has a scope that "compensates" but neither this scope or the Excals really "compensate" in reality. They adjust the magnification to increase or decrease the amount of spacing on the crosshairs on a target at any given distance. Theoreticaly if you have a fast bow, you will need a higher magnification to "decrease" the amount of gap you visually have on a target versus a slower bow. It works, but if you knock the magnification off and not notice your impact points are now off, and you also are stuck with a high magnification on a fast bow which can be a pain in the butt at close ranges. The Hawke (like a few others) is fixed and you do have to deal with the 20, 33, 47 yrd impact points for example, but the quality is very good especaily for the money. What is really needed is a fixed power scope with adjustable crosshairs....that would be stinking cool, but the down side is that a fast bow will practicaly have the crosshairs touching to hit 20, 30, 40 yrds exactly....All of these scopeshave trade offs...
