Great for lots of weight

By Henrik Bilar on 07 Feb. 2020

I'm new to dry-suit diving, and I have recently got myself into a Northern Diver DiveMaster Commercial dry suit. I have to wear about 12kg of weight to become neutrally buoyant (in the pool), and I used about 8kg on a belt, and 4 in my BCD, but it constantly felt like the belt was about to slip off, and my trim ended up absolutely terrible. It was in fact so horrible to dive like this, that I considered giving up on dry-suits and diving in the UK. However, I made a last-ditch attempt to make things better by using a weight harness instead, and it is fantastic. I have only used it for one pool session, but my trim was perfect in the water - it was so good that I forgot about the dry suit (which is exactly what it should be like). I wore the following (in pool water): - 4kg in each harness weight pocket - 1kg in each back trim pocket - 2kg in my BCD pockets (each) Total of 14kg of weight. I'm trying 12kg of weight next week. I use an XXL buddy commando BCD, which is quite buoyant as well, and a steel tank. I'm very happy with the harness - it makes dry suit diving possible for me.

Decent Harness But Needs Tweaking

By Sarah Rimmer on 04 Sep. 2022

Bought this harness to replace my old one. Upon first impressions, the harness is sturdy, well made, comfortable and can hold enough weight for me to be able to use my drysuit in the sea. The size can be altered to fit but if you're as skinny as I am, this will cause the material at the back of the harness to bunch up (I'd have done better with an XS but that size is not available). I cannot comment on how this affects comfort while diving as I have not yet been able to try it. One issue I've found was that the velcro in the pockets causes some difficulty when trying to remove the pockets for emergency weight removal. Neither myself, nor two other divers were able to get one pocket out as it simply would not budge. To counteract this, I've had to cover half of the velcro patches with a strip of fabric so that it is not as strong and the pockets can be removed in the event of an emergency. I suspect the velcro will lose it's strength over time, which will be more ideal.

Very good and well thought out.

I just bought the weight and trim harness. A very well-made piece of kit at 1/2 the price of what the BCD trim pockets would have cost me. I used it yesterday for two dives and was very happy. It has details/features you would expect in a kit 3X the price. Thanks, Ndiver. Customer service is top-notch.
