    Thanks for a practical question. Not at this time. I'll see how things go but I don't have the stock to offer both.

    It is a 12.5mm radius. Fits perfectly thru RockExotica SwivaEye and I'm not sure what the opening is on the gyro. Good question and I'll post that on the HHxf page.

    It takes me about 30 seconds to tie and get right. One of the beautiful things of this hitch is that it engages so reliably.

    New HitchHikerXF

    There is a debate there that I won't have but look closely at the hitches. The hitch I am using has a bight of cord that lays flat against the climbing line, on the left it is captured but on the right the cord goes straight past it and directly to the eye of the Dogbone. This is what makes it...

    This is one of the small safety related improvements of the Swing Arm. This Link with time stamp should take you right to the spot in the video.

    Isn't diversity great. Reminds me of a song that says, if you only see black-and-white you miss all the colors. Anyway, I literally have a wall in my shop that is 8' high and about 30' long covered in various climbing climbing gear. I have had the request many times to make the dogbone...

    New HitchHikerXF

    The new HitchHikerXF is now shipping. I think it deserves its own thread so I'll start it out. This link will take you to the manual, videos and other relevant information that can be updated as needed. Questions and comments are welcome. I'm not posting this just to sell the device but to...

    Tips and Tricks

    It seems easy to see a ratio of forward movement to upward movement and think, 1:1 MA Just like the difference between hauling and climbing we need to make sure we are comparing the correct numbers. So the distance traveled in this case for a 45 degree angle is 1.41 and the distance elevated is...

    Tips and Tricks

    One more observation on Mechanical Advantage. Look at the image below, imagine it is an inclined plane that has MA, like a flight of stairs. In this case you walk forward 1 foot for every one foot you go up. Rise over run building code kind of stuff. What is the ideal MA? (Answer in the...

    Tips and Tricks

    So the reoccurring discussion continues. I remember doing a video and trying to explain hauling vs. climbing. Try to see the difference, don't let moving pulleys and counting lines confuse you. This little test can be done with your rope and some tape. MA is simply a ratio, like a game of...

    Tips and Tricks

    Sure, force, but also distance or speed. I add this because sometimes seeing force is like seeing the wind and "seeing is believing".

    Expanding the use of my Hook system

    Agree that it is totally about risk assessment, knowing what they are, how they may be mitigated and then applying to ourselves or (if appropriate) those we are responsible for. It's the "I" in my comments that work for me.

    Update to the SAKA-mini-MAX

    You send them both down? I can understand parking the knee ascender but the foot ascender is such a valuable tool. I hauled a 50 pound auto belay up the tree using my foot power, RollNLock, loop runner and carabiner. I can lift 6-7 hundred pounds using a 5:1 set on my climbing line and using...

    Update to the SAKA-mini-MAX

    minor or not, it was something I wanted to fix. This actually folds up better than the mini and makes a tight little bundle that does not catch or get in my way at all.

    Update to the SAKA-mini-MAX

    Thank you Steve, I tried to tag you but it didn't work and I did not want to take advantage of your willingness to assist. I'm so very honored.

    Preventing Panic Mode

    Do you wear gloves? I use those foam nitrile cut out a few fingertips and they work great and find that I don't have to use so much strength to get the same grip on a small diameter line. I think I prefer that to a tooth ascender above. Yes every multicender is a little different and has a...

    Rope runner pro

    Just have to say amen to this. Understanding how these things work will allow safe use under different conditions using a wide spectrum of techniques. That is not so easy given how devices respond differently and how tree access and movement varies widely during a climb. Not everything is in...

    That's because the rental rates and insurance are astronomical.

    Preventing Panic Mode

    Examples. Hitch Hiker, the friction hitch needs some tension to stay next to the climbing line to self engage. The wrench needs to stay off the top of your friction hitch either by the tether length or some other means. The rope runner the bird needs to lift so that it can engage the rope. On...
