Climbers and cavers and more recently tree surgeons have been ascending and descending ropes safely for a long time and none of these more expensive bits of kit developed for the boating market seem to surpass the safety and strength of devices like Petzel Ascenders, where the rope cannot physically become detached from the ascender without the securing snap link first being removed. 2 ascenders and two snap links at under £100 cannot be beaten and these devices can also be used to assist in MOB and other rope retrieval and hauling uses.
