Product Review of Bohning Accu-Laser By Mark Burrows
The Accu-Laser or to give it its full title, Accu-Laser, Calibrateable Laser Bow Tuning Tool made by The Bohning Company Ltd of Lake City, Michigan, USA is a specifically designed tool to help you set up a bow or to check your current bow set up. It comes with a laser pointer dovetail arm, sight block arm and a bridge mount in a hard plastic Plano carry case and a very informative instructional DVD on the set up and use of the Accu-Laser. (Hover your cursor over the image to read the photo caption).
The laser can be attached to your existing sight dovetail bracket, although I must assume it only fits specific sights as I tried three other brands and none of them suited the dovetail, or it can be attached to your standard sight holes with the sight bracket supplied, but this means removing your sights. Both these attachments fix the laser on the inside of the bow between the front of the bow and the buss cables.
Of the three mounts supplied, I found the bridge mount to be the most useful. It is attached to the inside of the sight window into the back of the sight attachment holes, still between the front of your bow and the buss cables. This allows free movement of the laser but enables you to set up all the other equipment on your bow without interfering with the laser. The one disadvantage here is of the 8 bows I tested, 3 did not have the sight holes extend through to the face of the sight window. None of these 3 bows had dovetail mounts that suited the Accu-Laser, so the existing sights had to be removed.
The Accu-Laser can be a little fiddly to set up - it would certainly be a lot easier if you could put your bow upright in a vise as demonstrated in the Bohning DVD. You will also need four different allen keys to do your adjustments to the laser. It would be much easier if they had used the same allen head for all the bolts. I know the larger allen keys give a stronger bite on the bolts, but you are not going to shoot with the Laser attached so I don't see the necessity to lock the bolts up rock hard. That said, once you have done it a couple of times, it would be quite a simple operation.
Before going any further, you have to calibrate the Laser. This is a relatively simple procedure. The DVD shows clearly how this should be done and in testing several bows I did not have to change anything after the initial calibration. The laser head is then moved from side to side until the red dot picks up the string at the nocking point, and then locked into place. The laser can be rotated 360 degrees, which will pick up the top and bottom cams of the bow and runs along the length of the arrow.
The rotation of the laser has the potential to show up canted cams or even twisted limbs and being able to run the laser dot down the length of the arrow, gives you somewhere to start when setting up your rest. This will work well on two cam bows but on the three solo cams I tested, the bottom cam was offset so I was unable to run the laser dot down the length of the string. I could still however line the laser up in the centre of the solo cam configuration.
The Bohning Accu-Laser is certainly a well made piece of equipment and it does what it is meant to do without a great deal of difficulty. Whether it would be a useful addition to every archers tool box would be debatable. If you were a one-bow person, after your initial set up, further use of the Accu-Laser would be limited unless you owned a pro shop, were a bow manufacturer or needed to test and evaluate bows, like journal writers. However if you like to tinker or you put a lot of bows together, then I could see some advantages in owning one. If nothing else, you would be popular at your local club.
