I'm a BCA Member so I answered.
I wear through suits (well, here in TAG just pants). I sew my own this saves money means I spend about $40 on supplies but if bought, it would be $85-$100. Let's say $100 for ease. One a year.
One pair cave shorts a year, again I sew these, so its about $20, but bought would be $50. One a year.
(Our stuff is sharp with all the project caving started to do, I get tears through thick cordura in one trip.)
Kneepads - $40. One set a year.
Elbowpads - $20. One set a year.
= $210/year
New cave pack $50. Every 2-3 years.
New sit harness. $100. Every 2-3 years.
Replacement carabiners, ascenders, trying something new, etc. $200 every 2-3 years
= $350 / 3 years = lets say $115/yr
Stuff never replaced so had for six years of caving:
Helmet - $80
Light - started with $40 light, then upgraded to Bif's duo insert $120, now Rude Nora $700
Chest harness/roller, most my main ascenders (two full systems, ropewalker and frog) - $600
= $1540 / 6 years = let's say $250/yr
So total average per year...
$210 + $115 + $250
= $575
Which is currently 460-GBP
This does not include the two miles worth of rope in my garage...by my SO buys the rope. His spending would be higher than mine.
I voted 200-400 before adding it up. Before Brexit, that would be correct
It won't let me change to over 400. It's basically borderline depending on exchange rate.
OH should I count my 4x4 Xterra in this? If so, add $8000
And if I should include photog kit, add about $150/year.
