    Sure, I'm still up for it!

    Ok, just got the shipping notice on the paper.  Shows that the expected arrival is this Saturday via Fedex.  I'll let everyone know that's going to get some of this paper when it actually arrives via PM.

    FYI.

    OK, that's 4 then.  I don't really want to subdivide any further as this will now be 50 sheets each.  I've ordered the paper today and I'll let the LGNE, Great Birds, and Sharpbiker know when it arrives.

    Ok, it's up to a 3-way split now!  Anyone else?  Make it an evenly divided 4-way split?

    Larry,

    I'll place the order and will let you know when it comes in.  If anyone else indicates that they want some, I'll do the split up to 4 ways, otherwise if it's only you and me, we'll split it 50/50.  It seems like it takes about a week to receive stuff from RITR, just fyi.

    Thanks!

    LGNE, as far as I know, there's no order being discussed.  I had previously ordered some paper and since the amount that I needed left me with some extra, I'd offered to pass out samples to anyone that requested some.  If I order more, it would be a 200 pack of the All-Weather paper which would cost $28.  That's a LOT of paper for caches!  I'd be glad to split this for someone for 1/2 the cost.  I can't imagine that anyone could burn up a 100 sheets!  Something like a 4 way split (50 sheets each) would also be reasonable.  The item being discussed is indeed black 8.5 x 11. 

    So, if you or anyone else is interested, I'll place an order and split as needed, either in lots of 100 or lots of 50 depending on interest.  Let me know!

    On the samples that I have, that is the RITR All-Weather and Duracopy versions, both of these require a laser printer.  That works for me since I have a laser at the house.  Inkjets work poorly on both of these versions.  RITR has a product called 'WeatherJet' that CAN be printed on with a laser, but it is stupidly expensive at about .78/sheet in packs of 100.  That paper is similar to the DuraCopy paper, but has a specially treated surface that absorbs the ink from the printer. 

    So my recommendation for printing the logs sheets for me personally is very easy.  I use the templates from here http://www.techblazer.com/geocaching-log-sheets/ but modified slightly as I cut them to 1" or 2" widths as they seem to be the most commonly used.  This of course works as I have a laser at home, a small very inexpensive Samsung unit, although it works very well. 

    Right now, I only have one cache hidden, so my main use so far, is as replacement logs when i come across ruined logs in caches, an all too frequent occurrence here in Houston!! 

    I'd be glad to print some logs for you if you tell me what you want.

    OK, I've sent out samples this morning to all that have requested them so far.  I can send out samples to 2 more people then I'm out.  Please let me know if anyone else wants samples.  First come, first served!!

    FYI.

    I try to log all my DNFs for exactly the reasons that Thot stated in his article.

    Yep, the All Weather paper is very, very good and you've certainly figured out the most economical way to purchase it.  My .15 cent/sheet price was for the very small quantities.  I think I'll do the same, that is print off a bunch of logs and cut them in 1" and 2" widths and offer them at meetings for free.  I certainly want to do my bit to eliminate slimy-moldy-torn-impossible to write on logs! 

    Great work and a great contribution to geocaching!

    One thing I forgot to mention:  I still have a few extra sheets of both the All-Weather and the DuraCopy paper.  I'll send two sheets of each to anyone that requests via a PM.  I'll do this until they are gone.

    Completely Arcane Review - Paper - Part 2 - Long term tests
    I wanted to post some further results of some very long testing that I've completed on paper.  This follows up my original 'completely arcane review - paper' from a few months ago.  I'm sure that this will solidify my position as an 'uber-geek'! 

    First of all, I want to thank ProMed Rick for sending me a few sheets of the iGage Weatherproof paper for testing.  Here's my observations on that media.  First, it's slightly cheaper than the RITR DuraCopy product.  It is a very good product and will serve well in very extreme conditions.  However, it's not quite as good as the DuraCopy product, at least in my opinion.  It has 3 downsides (although they could be considered somewhat minor). 

    First, it's mechanical strength isn't as high as the DuraCopy product.  The DuraCopy is impossible to tear by hand and the iGage material can be torn by hand, although it's very difficult to do so. 

    Secondly the iGage product's base color is off-white, in fact very yellow as compared to the DuraCopy.

    Thirdly, the iGage can be cannot be written on successfully by a wide range of pens/pencils.  I was never able to write on the material successfully with a pencil and most ordinary pens didn't work very well either.  The RITR pen worked well as did Sharpies. 

    So, if you want a completely waterproof paper that can be used completely submerged and that lasts roughly forever, I'd recommend the DuraCopy.

    The other testing I did was some very long term testing of both the RITR All-Weather paper and the DuraCopy paper.  I also used an ordinary strip of 24# copy paper as a comparison, but as you'll see that didn't last at all.  I marked on strips of each paper with a RITR pen, a Fisher Space Pen, a pencil, a G2 Gel pen, and a Sharpie.  Next i did a series of tests that turned out to last almost 3 months in total.  Note that with the All-Weather and the DuraCopy papers, the exact same samples were used for the ENTIRE test sequence below.  I did NOT change out samples between test sequences. 

    Here's the testing sequence that I did. 

    I did a series of 10 cycles of 30 minutes immersed in water, followed by a air drying each paper sample.  This only took a couple of days.

    I then did a series of tests lasting one month in which I let the samples soak all day and then dry all the next day.  So this test sequence resulted in 15 wet/dry cycles.

    I then did a series of test where i immersed the samples in small, uncovered containers and let the water evaporate.  I then repeated this over 60 days.  This resulted in somewhere around 8 complete test cycles. 

    So, what were the results. 

    Ordinary paper - During the initial testing (the 30 minute immersions), after only 6 cycles, the ordinary paper was completely useless.  It had lost all it's mechanical strength and could not be removed from the water without tearing into multiple pieces.  I abandoned further testing at this point.  This proved to me that there's very little point in trying to dry out logs in the field.  Simply replace them as even one wet/dry cycle destroys whatever tensile strength the paper had. 

    All-Weather and Duracopy - both are fantastic materials.  Each sample pasted ALL testing with flying colors and after all tests were completed on all test sequences on the SAME samples, each was as good as the day it started!  The All-Weather still acted like ordinary paper, but has about 2X the tensile strength as ordinary paper, wet or dry, and never showed any sign of deterioration.  The DuraCopy never even gets wet!  You simply shake the water droplets off, and it's completely dry. 

    So my conclusion is that for most caches, the RITR All-Weather material is more than sufficient as it appears to simply never lose tensile strength or appears to deteriorate in any fashion.  If you would have a completely submerged cache, then the DuraCopy may be worth it.  Keep in mind the price difference is .15/sheet versus .65/sheet respectively, so the cost/benefit is highly in favor of the All-Weather for almost all uses. 

    Finally, with respect to writing instruments, I noted the following:

    RITR pen - Without a doubt, the best writing instrument for adverse conditions.  The ink simply never runs and appears to be the most permanent. 

    Fisher Space pen - Although the pen cartridges appear to be the same, they definitely do not work the same under wet conditions.  The Fisher Space pen ink diffuses badly through the paper with repeated wet/dry cycles.  In fact at the conclusion of the test, the Fisher Space pen markings were just one bit color blob and were completely illegible.  This goes along with that Davarle had noted.  The Space pen marks the paper well, but it appears that it's designed for a totally separate purpose versus permanence under wet conditions.  It does mark well on many surfaces though.

    Pencil - Works, but tends to fade a bit over time during repeated wet/dry cycles.

    G2 Pen - Works, but not quite as well as the RITR pen.  Surprisingly durable image over repeated wet/dry cycles.

    Sharpie - Excellent.  Very close in performance to the RITR pen.  Has the obviously advantage being available almost anywhere.  So unless someone wants to spend the extra for the RITR, the Sharpie series works very, very well indeed.

    I hope the above is helpful.  I know that I've convinced myself to only use the RITR All-Weather paper.  In fact I always carry some with me, cut into strips for replacement logs.  With this stuff, you can throw away the plastic bags (which always get damaged quickly and become useless) and never have to worry about mushy, deteriorated logs again!

    I've never found it in Houston.  I ordered mine directly from Rite in the Rain company.  See http://www.riteintherain.com/ for their website.  I ordered both the "All Weather Copier Paper", which is compatible with a laser printer and the DuraCopy paper which si also compatible with a laser printer.  They also have a product called WeatherJet which allows printing by inkjet printers, but that stuff is even more expensive than the DuraCopy product. 

    If you need some, as per my earlier offer, I'll send you 2 sheets of the All Weather paper and 2 sheets of Duracopy if you pm or email me with your address.  i can also cut them into 1" or 2' strips prior to sending them if you want as I have a very good paper cutter that makes quick work of said task.

    Let me know!



  14. mvh1954 added a post in a topic Keeping a cache dry   

    If you want something almost completely indestructible use the RITR Duracopy paper.  That stuff is completely waterproof and has such high mechanical strength that you cannot tear it by hand.  It can be printed on with a laser printer and most pens work on it also.  The best pens for use on it are the RITR waterproof pens or running a very close second is an ordinary Sharpie marker or pen. 

    I've tested this stuff exhaustively for both caching and 'other' professional uses.  It's fantastic stuff.  The downside - cost is .65/sheet. 

    For most uses the ordinary RITR paper is sufficient.  It can stand repeated wet/dry cycles and never loses it's mechanical strength, wet or dry.  However, it does absorb water, but quickly dries out.  It has about 2x the mechanical strength of ordinary paper, but maintains it wet or dry and its tensile strength doesn't deteriorate with repeated wet/dry cycles. 

    I'll update my earlier post about extended paper testing, hopefully later this evening for everyone's general info.

    I believe that you've made an astute observation.
