HAAS 08-98110 Velox Ascent System

If you have ever wanted to climb with two foot ascenders, now you can! The HAAS is a non-traditional foot ascender that can be used in conjunction with a traditional foot ascender on the other foot. The HAAS allows you to walk up a rope as if you were walking a ladder, making it one of, if not the fastest easiest ways to enter a tree. The HAAS works great in double systems as well as SRT, in a double system all that is needed is a HAAS and a traditional foot ascender, both can be purchased at Russo Power Equipment.

The bungee is terminated at the top of the HAAS Velox, travels down through a channel to the bottom where it is wrapped around sealed stainless steel bearings inside of a machined aluminum block for minimum friction. It then returns back up a second channel where it is tied to the snap. The result is 31 inches of inline bungee are contained in the system at rest, allowing 30 inches to be extracted under load. Bungee is replaceable in under 5 min with no tools!

Easy to Use
Straight Inline Pull
100% Captured advancement of other foot
Can be used in right or left foot application
Allows for very fast ascent

The regular HAAS puts the middle of the ascender 16 inches above the top of your foot the Long HAAS puts the middle of the ascender 19 inches above the top of your foot. 

*Please see HAAS Tree Gear Set Up Video to determine the best fit.

How to find the correct length:
Lower yourself so your feet just touch the ground but you are still fully suspended.
Measure from the top of your foot to the bottom of your hitch, this is the total space available for the HAAS to operate.
If this measurement is less than 36 inches you will get better performance from a regular HAAS.
If this is 37 inches or more you would benefit from the long HAAS.
If the measurement is in between, either size will work (there are a few inches of overlap)
