    Met office individual peak / fell forecasts

    The Met office have finally followed through on their threat to Web 2.0 their Mountain-Safety website (boo hiss), so it doesn't work over WAP or with 'dumb' phones: However, they've also launched a load of specific...

    'Cave Link' Text-Only Cave Radio

    During the summer 2013 Expedition to Tolminski Migovec, Slovenia, Imperial College CC very kindly had the loan of a 'Cave Link' radio system from the manufacturers. This is a text only system, and was found to be extremely useful for exploration logistics...

    Found Camera - Olympus Mu Tough - PYO (dead)

    Found a Olympus Mu Tough in the start of the resurgence of PYO. I suspect it had been swept through the cave during a flood pulse, water inside the camera so it's clearly dead but the SD card still works. The SD Card reads OK - photos show a group of young (guess late primary school age)...

    Does anyone know the longest (from an entrance) point one can reach in the UK / in the world? There's a cave in America, Fort Stanton Cave ( Snowy River Passage), with a point over 12 miles (19.3km) from the entrance: I've done...

    New Sony Actioncam Announced

    This new product just announced by Sony looks really potentially quite useful for caving / diving: Unlike the GoPro it seems to have a much larger aperture lens (thus more light gathering ability), and a large high-sensitivity sensor...

    Gingling - Climb below Stalactite Chamber v. loose

    Was down Gingling on Saturday - the climb in the slot below stalactite chamber was extremely loose, some fairly large chunks coming down as the cavers in front climbed up (with great care). Rather worryingly, it looks as if the much larger boulders are falling towards the bedrock of the wall...

    Estimating flow rate from noise

    We're dusting off our plans to build some dataloggers for installation over a year in an alpine cave. It's easy enough to buy sensors to do temperature, pressure and humidity (though it might saturate), but one thing we've considered trying to do is estimate the flow rate of the cave by...

    Found: Stop in Notts I

    Stop found, on its attachment carabiner, in the streamway midway along the traverse on the way to the sump (fallen down into the stream, near the old ladder route). The wheels are a bit pitted, so it's possibly been there a while, but otherwise seems serviceable. Describe the krab & the stop...

    High CRI LEDs for Photography / Colour Calibration Underground

    I split this off from the Bisun review, as I didn't want to hijack the thread, interested in any comments! Only one year off! For a photo lamp, I'd imagine you could run into CRI problems quite quickly. It's certainly a headache to have...

    Experience with Adventure Medical Kits Emergency Bivvy Bags ?

    Do any cavers out there have any experience with the (relatively) new Adventure Medical Kits Emergency Bivvy Bag? They seem quite interesting, sort of halfway between a 'good old' polythene survival bag (Caving Supplies quote 90g, 182x83cm, ?4) and the slightly OTT Lifesystems Blizzard bags...

    Imperial College CC: Izgubljeni Raj 2011

    Imperial College CC is back from another very successful 4-week summer expedition with the JSPDT on Tolminski Migovec, Slovenia. Earlier this year we won the Wilhelm Putick Prize (nagrada Viljema Puticka) for 'the best achievement in cave exploration in Slovenia in 2010', for our Vodna Sled...

    Bosch Uneo External Battery Modification

    I just modified another Bosch Uneo for bolt climbing use this summer, and took a good few photos of the pristine gearbox + my modifications, to help anyone else that decides to get one themselves. I choose to remove the internal...

    Sub-visible Fluorescent Dye Tracing?

    To an extent this is a continuation of a previous discussion of dye tracing: On the practical side, I thought people may be interested to see that there's a 'shop' on eBay offering Fluorescein and Rhodamin-B for around ?5-6 per 100g bag...

    Information on Su Palu, Sardinia?

    I'm going back with Imperial CCC to Sardinia to have a more in depth look at Su Palu (clearly the best cave on the island!), and was wondering if anyone had any information out there that was more in depth than that available in the SMCC guide? We were hoping to get a good few days exploring in...
