    Yesterday, I completed transforming my diving rig to HOG and I finally lost my console. My instructor replaced it with a really cool DIR Zone SPG and a Suunto wrist mounted compass. Everything about HOG has made perfect sense to me so far, but I don't understand why my instructor went to the trouble of taking the compass out of a perfectly good wrist mounted boot and treaded bungee instead. I know there must be a reason. Could somebody in this forum enlighten me?

    I use a Suunto wrist mounted compass with dual bungee straps. I don't know about HOG, but I like the dual cords because if one breaks you have built-in backup.

    The advantage of wrist mounted instruments is you can read them without much effort.

    The advantage of bungee mounting is ease of donning.

    As you were the supplier to the bungee mount I guess you could say that this is straight from the horses mouth, so thanks for explaining. It would have become apparent after a few dives with the compass, though I wish he had supplied thicker bungee. I checked out your site and I see that you supply bungee mounts for Suunto Gekko computers too. Now, that really is hard to put on. Expect to receive an order from DDT Tokyo soon.

    Well, there's another advantage to bungie -- it doesn't come unbuckled when you least expect it.

    Plus, if you set up the bungee correctly they compensate as your exposure suit compresses. No more tightening of the strap or moving a wandering compass back up your arm!

    Of course, this is only for wetsuits. If you dive dry a wandering compass shouldn't be as much of a problem.

    I’m trying to figure this out, how do I set it up correctly?

    I’ve got the generic Sherwood and finally located someone’s most helpful photo showing Zip tying the bungee (danged if I could figure that one out on my own.) I’m in a 3ml and a 5ml wetsuit and want it up on my forearm. Right where it looks like a slip slide down to interfere with what’s my wrist.

    I’ve got a bungee backup keeper for my wrist computer (had 2 wrist band of some sort fail in the 1st year I dove.) I’ve made it adjustable with Fisherman’s knots and thinking to do the same with this compass.

    Is there an easier less complicated and bulky way? Am I over thinking this and the bungee will sorta stick to my Hyperstretch enough there will not be such a fine line between uncomfortably tight and staying put?

    Well, I'm not sure how you personally would go about doing it. I have one of Tobin's mounts so the only thing that I had to worry about was the length of the bungee used. And that I did by trial and error. Tried one length, then adjusted it until it felt 'right' then trimmed it down.

    What I meant by 'setting it up correctly' is having the bungee slightly stretched around your arm and wetsuit on the surface. That way, as you descend and the wetsuit compresses, the bungee will lose some of its stretch but will still be snug around your arm because it was stretched out to start with.

    That part is hard ... well at least it was for me ... because I found that there is a fine line between too tight and too loose. A good starting point I think is having the unstretched bungee loop to be just slightly wider than your naked arm. That way even if your wetsuit is compressed down to the thickness of paper it will still be snug enough around your basically naked arm.

    When diving drysuit it's not always a good idea to use the bungie aproach. If you get a leak on your glove or at your cuff, you can easily constrict the flow of cold water with the standard wristband by tighten it a few notches... With a bungie it's nearly impossible.

    And for the argument that a normal wrist band becomes unbuckled, I have yet to experience that one, is it really that common?

    Ok, the zip tie thing isn’t working.

    I did get a strap-on boot but taking that back, too big for my arm, like wearing a saucer.

    Any hoo, back to the drawing board. I have this little boot for a retractor. (The retractor lost a significant portion of retract ability. I know, like I was told it would.) So my next bright idea is to just drill holes in the boot for Bungee.

    Thanks for the help.
