Adjusting the backplate/harness

It's important to have the harness properly adjusted.
It doesn't have to be super tight but it shouldn't be sloppy either.
This is a guideline that will help you get it right.
If you are tall like me, (6'5", 1.95m) you may need to wear the backplate slightly lower than in the pictures.

When you do the adjustments try to wear something of similar thickness to your underwear or wetsuit.
Adjustment checklist:
- Make sure the harness is properly weaved.
- Adjust the length of the shoulder straps.
- Adjust the height of the shoulder D-rings.
- Check that it's evenly adjusted.
- Adjust the waist strap.
- Adjust the left D-ring.
- Adjust the length of the crotch strap.
- Adjust the back D-ring.
1. Is the harness properly weaved?
Before we start, make sure you have the harness properly weaved.
It should be a one-piece harness and it must be weaved like this to work. |

2. The length of the shoulder straps.
Adjust the harness so that you can easily reach back and touch the upper part of the plate.
The top of the plate should be an inch or so below your prominent vertebra (the one that sticks out).
Don't put on the crotch strap or waist belt just yet.

3. Placement of the shoulder D-rings.
Extend your arms and close your eyes.
Make sure your thumbs touch the D-rings when you bring your arms in.
Make sure the D-rings aren't too low - they will restrict your range of motion otherwise. |

4. Make sure that the right and left side are the same.
Double-check that you got the same shoulder strap length on both sides and that the D-rings are placed in the same spot.
Adjust if necessary. |

|
6. Adjust the left D-ring.
Align it with the center of your body.
|
 |
|
8. Adjust the back D-ring.
Sometimes you need to clip things to your back D-ring.
Put it as high as possible but not under your tanks.

Tips and tricks
If you intend to scooter I recommend fixating your crotch strap with bolts
or by sewing when you are satisfied with the adjustments.
Several people have had the crotch strap come undone on serious dives.

Now you are all set up!
Happy diving!
