11 Reasons the Petzl ID is better than a Fisk

What can we say about the Fisk Descender? It’s a decades old device. It’s proven and well liked by many industries. It’s rock solid, rugged, easy on your rope, and you’re already familiar with it. What’s not to love?
Check out this post by our friend Wade wrote on how wonderful the Fisk is.

Now, if the last paragraph resonated with you, you might want to take a deep breath. This post might just shake you to the core (too dramatic?). The thing is, there are now better devices available. In particular, the Petzl ID is a phenomenal device. Here are 11 reasons why it’s better.


FISK VS PETZL ID


     11 Reasons why the ID is better than the Fisk.


  1. It is self braking
    Self braking means that if you let go of the device it will stop. With the fisk you have to keep a strong grip on the tail end of the rope or you will take a quick descent (i.e. fall).

  1. Easier to load and operatePetzl ID is easy to load
    You may think that the Fisk is a piece of cake to load, but you probably didn’t think that the first time that you saw one. The Petzl ID is much easier to load and operate for experienced techs and green hands alike. It has a picture of proper loading on the front and instructions for using the handle on the back. To go down, pull the handle. To stop, let go. No tying off needed.

  1. It is anti-panic
    When you panic, a natural reaction is to clench up. This can be disastrous with many devices depending on what you happen to be holding when you panic. With the ID if you pull too hard the device stops. If you are annoyed by the anti-panic, Petzl makes a version called the Petzl Rig which doesn’t have it (it’s still self braking though!).

  1. Will catch if loaded upside downPetzl ID will catch if you load it upside down
    Of course, if you managed to load the Petzl ID incorrectly, it has an ingenious lever which makes the device lock up, preventing descent (note that the Petzl Rig doesn’t have this feature). The Fisk has no safeguards against incorrect loading.

  1. The ID is lighter
    You might enjoy carrying unnecessary weight for the work out, but for the rest of us the ID is going to be much better. The fisk weighs in at a hefty 2.5 lbs compared to the ID at only 1.2 lbs. That’s less than half the weight!

  1. Effective hauling devicePetzl ID can be used as a hauling device
    The ID can be used in a hauling system for progress capture. If you need to switch from lifting to lowering, you can instantly make that change. This is a huge benefit. The Fisk can’t touch this one.

  1. ID goes up, down, and all around
    The Fisk pretty much just goes down. The Petzl ID on the other hand can be used in a variety of other complex maneuvers. It can be used for ascending, descending, rebelays, and much more. To get an idea of its many uses, search for SPRAT Level 1 maneuvers on YouTube.

  1. The ID is easier to inspectPetzl ID is easy to inspect
    Petzl has specific criteria about how to inspect the ID and when it needs to replaced. This doesn’t exist on the Fisk, and the decision about when to retire it is much more subjective.

  1. Meets basic ANSI requirements
    ANSI says that descent devices should be self braking and anti-panic (see reasons 1 and 2). The Petzl ID meets this requirement and the Fisk doesn’t. Don’t care about ANSI? More power to you, but be prepared to justify that to an OSHA inspector should they show up.

  1. It can be permanently locked
    Petzl gave the ID the ability to be locked in place with the use of a little pin you are able to take in and out of the device. THis means you are able to set up and use the ID in a rescue kit, without having to adjust it. Also, you can keep your ID just the way you like it and no one can move or mess with it.

  1. It has a longer maximum descent length than the Fisk
    Icing on the cake of reasons we love the ID, it has a longer descent length than the fisk.

        Does the Fisk Descender do anything better?

If we’re being fair, we should point out a few things that the Fisk does better than the Petzl ID.


  1. Can be used remotely
    The Fisk can be used to remotely lower a load or person in a rescue. The Fisk Descender can be anchored up above and the user can hold onto the tail end on the ground. Since the ID requires you to operate the handle, you have to be within arm’s distance of the device.

  1. The Fisk can use a wider range of rope sizes.
    With the ID you have to choose the small (10 mm – 11.5mm) or the large (11.5mm – 13mm). If you are commonly having to work with different size ropes the Fisk Descender can be more versatile.

  1. The Fisk makes for a better weapon
    The Fisk Descender is heavier and has no moving parts. It is by far the superior device to have in case you need to use it as a weapon.


     Conclusion

The Fisk Descender is a great device, but in the last few decades new types of devices have come out that are safer, more effective, and more versatile. There are a number of great self braking descenders out there, but the most common and arguably the best is the Petzl ID. It’s a fantastic device, and you should consider using it.
