Hello everyone,
I regularly need to lower science equipment at a constant drop rope, most often in water. Wondering if anyone could recommend a device that would help with this. Specifically I have a hydrolab (multiparameter probe) that only weights a few pounds, that needs to be lowered at ~2cm/s down into water, often over 10-50 m water depth. At 2cm/s it can take 30+ minutes to do a profile in a deep cenote/sinkhole, and manually doing this is not giving even quality profiles. Is there a mini-rack, belay device, pulley, or other system that could help with this? The idea is to tie this off somehow and have it just lower the instrument. I could add more weight if that helped.
All suggestions welcome!
Cheers,
Trish Beddows
