BASIC SETUP Your new Martin bow takes little setup to get started shooting. Please read and familiarize yourself with these starting procedures before shooting. Many of these procedures may have been completed by your authorized Martin dealer. After completing these simple steps, you will be more accurate and will have greater success from the start. A careful and thorough initial setup will make the tuning process much easier.
SETTING TILLER Taking a tiller measurement allows you to check the relative tension setting of the upper and lower limbs. After setting the draw weight on your bow, you will need to check the tiller measurement to make sure that you have adjusted your limbs evenly. On all Martin compound bows, “0” or even tiller will shoot perfectly. However, the tiller measurement can vary up to 1/4” closer at the bottom. There is no set measurement that provides peak performance for every shooter.
SETTING NOCK POINT Place a bow square on the string and slide the square down until it rests on your arrow rest. Then place a moveable nock set on the string. Using the measuring scale on the bow square, set the nock set at the proper location on the string. A good starting point for finger shooting is ¼” high, measuring from the bottom of the nock set to 90° on the bow string. Start at 1/8” high if you are using a release aid.
PARTS OF THE NITROUS CAM X-Module Module Module Screws Speed Bearing Base Cam CHANGING THE DRAW LENGTH Your Nitrous Cam may be an X ShootThrough system or a standard system, but the draw is adjusted basically the same. The threaded module has numbers and dashes on it that indicate what setting you are on while you are adjusting it. The dashes signal 1/2" draw increments. When you are adjusting the draw make sure that both modules are in the same setting.
SETTING THE CAM TIMING Wheel timing on a two cam bow makes sure that the nock travel through the shot is straight and level. It is important that your bow is timed well for greatest accuracy. Setting the timing is very easy, and you will be able to go through this step by step and set your timing like a pro. First, you will need to draw your bow back to full draw with your release and an arrow.
Let-Off Designation Let-Off Designation Notes an X Module Mounting Screw Holes Countersinks Notes an X Module Mounting Screw Hole Countersink OD I MIN M OD M NI MI Standard Modules Standard Modules use two mounting screws. The X module is noted with an X on the tail, it can be installed per the instructions below to make your bow a shoot through system. The (T) on the tail of the mod notes that it will fit on the top cam (NOTE: left handed shooters are the opposite.
CHANGING THE DRAW Tru-ARC cams are different from any other cam on the market. The thing that makes them special is when you move the modules, they automatically adjust the rotation of the cams for peak performance and optimum nock travel condition at each individual draw length. Your Tru-ARC cam comes with all the modules you need to cover all of the available draw lengths. You have a Long module marked with an L-(letoff) and a Short module marked with an S-(letoff).
rotation is pre-set at the factory and should not need adjusting, but refer to the position of the cams to the left. This is the optimum rotation. If it is other than what you see here, check your string lengths. DYNA™ SINGLE CAM The Dyna System is unique among all other single cam systems. The Dyna System has modular draw length adjustment, and can be adjusted in half inch adjustments within each draw length module.
STRING CONFIGURATION The string harness on the new Dyna Cam is installed according to the diagram below. Your string harness should be installed by your qualified Martin dealer. Pay close attention to how the Shooting String leaves the cam. Although cam rotation is not critical, use this diagram as a loose representation of proper cam rotation.
FINE TUNING YOUR COMPOUND BOW After completing the basic setup procedures, you are now ready to fine tune your setup for the best accuracy possible. There are four tuning methods described in this section. Some of these methods may not apply to certain styles of shooting. Read the introduction to each method carefully to make sure it applies to your shooting style. BARE SHAFT PLANING TEST The Bare Shaft Planing method of tuning works best when using a finger release.
Fishtailing Fishtailing relates to the arrow rest adjustment and the stiffness of your arrow. Just as before, start at about ten to fifteen yards and shoot three fletched arrows into your target. Using the same aiming point, follow them up with a bare shaft. After you get the shafts to impact with the fletched shafts, you may want to try shooting them at a longer distance for a finer indication of arrow flight.
PAPER TUNING Paper tuning will work for all styles of shooting. As you are going through these steps keep in mind that paper tuning is not chiseled in stone as the law of archery. It is a guideline for clean arrow flight. Many shooters find that their setup groups best when achieving less than perfect tuning results. For example, some target shooters set their bows to tear slightly high through the paper.
RIGHT TEAR (fletching tears to the right of point) This tear may signal: Note: If you are left handed follow these instructions in reverse. FINGERS: •Stiff arrow. This problem is cured using the following methods: a. Increase peak weight. b. Use a heavier point. c. Select a more limber arrow. d. Lighten cushion plunger tension, or use a weaker spring on shoot around rests. e. Make small incremental rest adjustments towards the bow. RELEASE: •Arrow rest is too far to the right.
MULTIDIRECTIONAL TEAR This tear may signal: •More than one problem with accessory adjustment. Move nock adjustment first until the tear is horizontal and follow Instructions for horizontal tear. •Clearance Problem. See that the arrow has adequate fletching clearance. •Wheels may be out of time. Check wheel timing. •Irregular or inconsistent shooting form. See a qualified archery coach or professional and have them check your technique. PERFECT HOLE This pattern shows clean arrow flight.
SUPERFINE TUNING SHORT RANGE GROUP TUNING Short range group tuning will work with any style of shooting. Best results are achieved when this method is used after completing the Bare Shaft Planing or Paper Tuning tests. This is a good ultra fine tuning method when space will not permit long range shooting. After completing the following steps you will have very clean arrow flight and a well tuned, accurate setup.
FLIGHT TUNING BROADHEADS Broadhead tuning will work for all styles of shooting. After you have completed one or more of the tuning procedures described in this manual, you can proceed with this final test to get your new bow ready to hunt. You will need three fletched arrows with field tips and three with broadheads that weigh the same as your field tips. Before you begin shooting, you will need to check your broadhead equipped arrows.
