Excerpt: Despite the price for what it is, I recommend that anyone who shoots in the winter using a Gitzo monopod to have one in their bag. It doubles as a little grip when the conditions get icy. I really like the extra stability it provides in sand as well. Sometimes I stay crouched for extended periods and the extra length of this spike allows me to hold my 500mm with one hand confidently. A word to the wise.
Excerpt: To prevent the monopod from slipping in the field this is more effective than a short spike or the standard rubber foot. Of course the problem of rotation remains. The price is too high; the spike is not even delivered with a protective cap (unlike the identical spikes for tripods)! I am also concerned whether the large leverage the spike can exert will eventually break the monopod which is rather fragile at its lower end - I will be cautious.
Summary: Improves the versatility of the monopod because it allows the short spike to be permanently available. The rubber foot encases it for normal use. I also have the longer spike which works very well in soft ground.The short spike should be standard not an accessory hence only 4 stars
Pros: Compact, Good Footing, Lightweight, Locks In Tight
Summary: This is a really useful accessory - and in some conditions it's pretty essential. All the more pity, then, that Gitzo doesn't supply it as part of the original monopod purchase!Mine stays fitted to the monopod most of the time. The covering rubber cap fits well, but can be readily removed (best done with a firm twisting motion). My only word of caution is, if you're travelling by air with your monopod in your hand luggage, do remember to remove the spike first.
Summary: These spikes do the job perfectly well, but don't come with a bag to put them in when not in use. This means you have potentially muddy spikes to put in either your pocket or bag.They are also metal, making them bulky and heavy to transport.
