All martins and ryteras do the same thing as well. It's a pretty nifty feature. [8D]

But howwwwwwwwwwww?[8D]

Basically you back the limb bolts out 4 turns at a time, then swap to the other limb bolt back out 4 turns, then the other 4 turns, etc until there is slack in the string/cables.

Also, on a shoot through system, you can actually time the cams and tweak draw length in minor amounts without even backing it out, you can take 1x cable at a time off the bow without backing limbs out even, the other 3 will keep everything in place with no press. It's pretty handy.

I have a regulat press and a portable that I used to carry for my friends on trips.

I have an older style full-sized press which is next to useless with the newer style parallel limb bows. I also have a portable press, but cannot use it with split limb bows.

Ofcourse, my new bow doesn't require a press.

Yes its worth it, i use mine a bunch, almost every time i work on my bow, depending on that i'm working on the bow.

I have a full press at the shop but at home I use a heavy cable that has a chaulk on either end. I draw the bow with one hand and my foot then insert the chaulks of the cable into either end of the limb at the fork then let down on the string. The cable takes up the tension on the limb and allows the string and cables to go slack. It's handy for in the field as it weighs nothing, but it has to be custom fit to each bow and it doesn't work if you can't draw the bow (i.e. broken string). It looks something like this: I------I

I have a bowmaster portable press.
