I recently read in John Chatterton’s site he likes to use a piece of 1/4” sisal rope so it doesn’t slip on the synthetic rope used for mooring lines, and it’s practically free. Have you ever used a DIY one like that?

Hi James, excellent video! Would have loved to have this on a previous dive in not so ideal conditions. You've talked about gear selection and maintenace for all dive kit, would you be able to make a video regarding assembling your first gear? Particularly with first stages and second stages, it was pretty daunting for me in the first instance!

thanks James for this interesting video.. as usual , unique videos..

That's a real neat idea, I've always preferred blue water ascents with an smb for this reason, but the Jon line offers a useful alternative

Great info as always. Thanks for sharing. Do you have your 2023 calendar done yet?

Nice, not a tech diver but was on the Spiegel bumped into all the tech divers trying to go up on my second dive 😅 that was interesting. Maybe they should see this video cause it was crowded

thank you for getting the name of the originator - Jon is one of the nicest guys you will ever meet and was very innovative. A finger spool makes a good makeshift jon line, and I find those nylon straps tend to slide in a bouncy current

Great vid

Interesting !!! Thanks for the info James, shout out from La Coruña -Spain 🤗

Hey James, great video! I think a quick overview on dive line going over weaves (flat v round), colors, and weight/diameter could be really helpful with your experience! Thanks!

Hey James, one question about Jon Lines: You're using a carabiner on the end, and many I've seen have a Garvin Hook. What's the pros and cons of each and which do you prefer/recommend, or what are the conditions to choose one or the other? I noticed the diver with the red line uses a Garvin Hook like it's a carabiner but another video on how to use them says you put the hook directly on the line (which is why it's ribbed for different thickness of line).

There is another use for the Jon line (here, in the Netherlands, we call it a "buddy line"). When diving in very bad visibility it is quite common to lose sight of your buddy and, as a result, having to surface to wait for the buddy which could be the end of the dive! Connect yourselves together using a buddy line and you cannot lose each other and so can have a relaxed, complete, dive. Similarly, if diving in strong current, it is a way of staying with your buddy. The downside of both these scenarios is that both ends of the line are moving independently and so, sometimes, the buddy pair get tangled together but this can be avoided if you are careful.

Hey, James... would a Jon line be a good idea when buddy breathing? In rough conditions, having a tough time holding on to eachother and moving up an anker rope. Thx for all the great content and tips.

I bought the job line clip, and just attached it to a 6ft dog leash, worked great on the Spiegel just as described

I might just do this for my three minute safety stop

Could you just pretie some knots to use your regular spool line?

Have u ever considered getting registered with GUE as they are more strict for tech diving and most people who go through them are not after a quick upgrade

I've clipped my reef hook to one end of my jon line and it can now be used for both hanging off a reef or a safety stop on a line

Dammit, now I need one 🙂

if the dive calls for a ascend using a line, I deploy my Jon Line. Even on recreational dives just for the safety stop on a busy line.

Hi James. Thank you for this vidéo about the Jon Line. I have a question 🙋‍♂ which ils off-topic to this subject. I plan on taking my advanced nitrox and deco procedures course next year in March 2023. My scuba shop which I‘m paying for thé course also will throw in an extended range course where I can go beyond 150ft or 46 meters. What is extended range and should anyone take this course par your recommendation? Thanks.

Not speaking for James but, diving below 130ish feet with air, raises serious concerns for nitrogen narcosis. Helium is usually recommended below 130 ft. Many consider helium once past 100ft. Therefore going Trimix at the depth would be considered safer, and more memorable, per my training.

I certainly understand the cost issue. Doesn’t make it any safer however. That is one reason I now dive closed circuit rebreather

Why not using a reel instead? Since you are referring to wreck diving, most propably you carry one with you anyway.

A reel uses a very thin twine so I don't think that would have the strength to hold a diver in a strong current. I'm pretty sure it would snap.

@@slyderace Depends on the reel. In the Isle of Man, we have very strong currents, and the Custom Divers' big reel is popular here. It's large and very well built.

I was surprised to see you use a carabiner (aka suicide clip) for this, rather than the hook type. I guess that since you won't be mobile while it's deployed, the snag hazard is heavily mitigated, but I have always been encouraged to avoid these types of clip in the water.
