Outdoors gadgets

We are always for new gadgets to try out in Pulau Ubin. Here are some we have bought.

Flashlights

The biggest collection we have tried are flashlights. Gone are the days we would carry heavy flashlights with bagful of expensive batteries and spare bulbs for camping overnight. New and evolving LED technology made flashlights a lot lighter, reliable, longer lasting and powerful at the same time. As tools, we are also looking for ones that is well machined with quality materials, and have been very impressed with SC600 Cree XM-L 750Lm Flashlight 18650 by Zebralight. Update 14 Nov. We have just ordered the new neutral white version (ZLSC600w). Update 28 Nov. We received the SC600w over the weekend and tested at the about to be demolished Bukit Brown cemetery. It emits a huge wall of light. To a group trekking there, its bright as a car with headlights on. Run time is impressive with a single 18650 battery used for a 2 hours walk, lasting much longer with AW 18650 3100 mAh battery which we would soon order. This will be our next durian hunting flashlight, allowing us to take census count of number of durians from the tallest tree, and allowing us to sweep for hours to find them as they fall and roll hidden in the jungle floor.

Digital cameras
It is tiring carrying a heavy DSLR to Pulau Ubin, with dripping sweat and oily repellents gumming up its knobs and switches.

The efforts paid off, like this baby owl taken in extreme low light conditions with a Nikon D3s. (Taken by Andy Ho)

But there are days where we have too many things to carry so our gear needs to be light. Nikon 1 series V1 camera looks promising. What I like so far its its ability to take fast moving subjects in focus. Like these dogs running and playing.

Helmet cam

Digital cameras nowadays are capable of motion videos. But few are completely waterproof or as versatile than GoPro 2 which is now available in Singapore. With so many questions from first time visitors about Pulau Ubin, short clips would be useful to get a feel what it is like and for archiving disappearing scenes.

Trail Cameras

I haven’t seen mousedeers and otters in Pulau Ubin which others have spotted. Other elusive creatures include swamp mouse with its white colored belly. Maybe I get lucky with this trail camera on special offer by Amazon.

Despite its flimsy looking construction, its small and comparatively cheap. Unfortunately it draws attention due to its blinking LEDs used to take infrared photographs in total darkness. One its first night I gulped when I saw a guy in shadow silently coming out from the direction I set the trail cam. Next the weather turn stormy and it rained heavily non-stop for a few hours. The silent guy have missed it and it survived the rain. Only one picture was taken but no animal was seen. Maybe its too fast. It must have spooked a village dog sleeping near us which jumped in fright and howled in all four directions. Must be a large boar. Hopefully we will be lucky the next time.

Walky talkies

Consumer walky talkies we used so far have been disappointing, with signal breakups just a few hundred metres apart. The Motorola TLKR T7 is designed for outdoor sports use. Then again it may not. I bought it for its included accessories like twin charging bay and that it is approved for local use without requiring a license or paying annual fees. Despite its limited practical use, the kids look forward to play with them during school holidays.

Handheld GPS

Garmin Montana

The Garmin Montana is a bright touch screen designed for dual function as vehicle GPS which you can use with free downloadable maps for many Asean countries. Although most GPS should work in Pulau Ubin, the Montana proved itself to be very useful when I was in Phuket. Despite pouring rain, I was able to navigate by listening to its spoken road directions through a ear-piece.

Ghost Month

August happens to be 7th month in Chinese Lunar Calendar. It is believed that hell gates opened up and hungry ghosts are everywhere. Visitor levels to Pulau Ubin would drop during this period as people prefer safety by staying indoors. For us, August is as good time as any to tour Ubin by night.

Ubin’s hell guards (黑白无常). Their job is to catch ghosts and send them back to hell. Link warning. Scary pictures.

Hell Guards

We hoped to make a spirit themed walk to Bukit Puaka area, a place considered by Ubin islanders as being haunted. Residents tell stories of being lost even in broad daylight in places they were familiar since childhood.

Despite being skeptics, we are hoping to be caught up in the same paranormal phenomenon. But this time with high tech tools to help us. My GPS is logging the location of every step we made. Its recording will show if we have been walking in circles or taken to Mars by alien probes.

We are also armed with the latest flashlights. This time with RA clicky high CRI LED lights fitted with longer lasting 17670 batteries. The lights also enable us to take better colored photographs. I also brought a Thrunite 300 lumen P60 style XP-G R5 3 mode drop-in. This drop in allows me to use Surefire 6P heads with forward clicky, fitted on Solarforce 18650 tube. They would be our high tech amulets against ghosts.

The walk was leisurely while taking nature photographs along the way.

Located 100 meters away from Malay Kampong, this bamboo clump was inhabited with interesting creatures including including a scorpion, slugs and insects that crowd and move together.

Spooky stories about banana trees have been passed from kids to another for generations. When I was little, I was told that the the banana flower is where the banana ghost hides during the day. If you tie it with string the ghost will grant you any wishes to free herself.

The village provision shop was still open late into the night. We soon found ourselves engaging in swapping ghosts stories. The one told about Noordin famous white ghost with a baby on her arms is most frightening. Another is sightings of a blue colored giant mountain spirit walking the hills of Bukit Puaka. And that was way before the movie Avatar came out.

Time passed, we decided to postpone our ghost trail after allowing ourselves to be spooked, discretion being the better part of valor.

We went to Ubin jetty. Fish were biting and this angler landed a snapper.

On the way back we heard mewling high up the trees. It turns out to be a rarely seen spotted wood-owl. It’s a juvenile bird calling for its parent. Adult wood owls emits a loud and eerie frightening sound which is commonly heard at Malay kampong area.

Have you personally seen or felt the presence of a ghost before?

Ubin for GPS exploring

Garmin 62s

I having been exploring Ubin with a GPS for a number of years. GPS devices like Garmin uses free satellite signals and all you need is the AA batteries to power them. With backlighting on full, they last about 8 hours so its important to carry fresh backup batteries. I am using Sanyo Eneloop rechargeable batteries which performs better.

Basic GPS functions.
Its perhaps unfortunate that GPS is full of geek stuff. The simplest function is to learn how to create breadcrumbs (‘waypoints’ or ‘landmarks’) on key trail features such as junctions, bridges or buildings for simple navigation.

As jungle trails are often featureless and following a winding path, next up in complexity is to learn how to set track logs. All you need is to set the GPS to record your trails as you walk. In the jungle, your trails appears zig-zagged looking like a bird nest due to inaccuracies due to tree cover. The track logs are then downloaded with free software to clean them. Once cleaned, the tracks can be uploaded back to the GPS for use later or shared online.

Track logs are also useful to embed GPS co-ordinates into your digital photos using GPISync, a freeware from Google. This way, you don’t have to tether your camera to a GPS or purchase a dedicated camera GPS which are usually inferior in terms of accuracy.

GPS recommendations.

My favorite GPS model was Garmin 60CSx which is compact and popular. It has since been updated with 62 series. With its buttons layout it is easy to access frequently used functions but typing names of places is difficult. For that, I bought a Garmin Oregon 450 GPS which uses a touch-screen interface. The cons for Oregon is the dim screen in daylight. Its big brother, Garmin Montana has a bright and large screen which serve its dual function as a in-vehicle navigator. Having tried all, my preference is Garmin 62s for its secure grip, followed by Oregon 450 for its touch-screen and compact size. The shop I usually buy from is Perfect Watch at Level 1, Sim Lim Square.

GPS Software.
Software like Google Earth, Garmin Basecamp allow you to clean your track logs or plan your hike in advance. New Garmin models are able to load satellite images by subscribing to Garmin BirdsEye™ Satellite Imagery. The annual subscription costs is US$30. The subscription is worthwhile as I am able to download detailed images for Pulau Ubin. I am now able to confirm position of visible landmarks with better accuracy. Its would have been a chore to take multiple readings 90 minutes apart. I found out earlier that Google Earth images are not accurately positioned and cannot be relied upon.

Sharing maps online.
The problem with GPS is the babel of formats limiting its usefulness. Fortunately times have changed and formats like Google Earth KML are becoming popular, allowing users to share their maps on-line.

Watch this space. I will be adding more tracks and locations of interesting places. You can also download the kml file and view it on Google Earth. With a bit of technical know how, you should also be able to download them into your GPS unit for your next trip to Ubin.

Other GPS features to consider.

More advanced units allow you to download routable maps that provide driving directions. Garmin users are able to download free routable maps for Singapore and Malaysia.

There is a profusion of smartphones with similar GPS functions. I pay little attention to such 3G subscription based phones. Overseas telecos are scamming the public with exorbitant phones bills. I was in Dubai when I accessed its 3G for less than a minute before turning off the phone and was slapped with $700 phone bill. You are in luck if you have a Symbian S60v3 smartphone such as Nokia E71 or E72. Garmin have a navigation software called Garmin Mobile XT. With pre-loaded maps you do not have to incur expensive data charges. I installed it on my Nokia E72 which have built-in GPS and compass, albeit mickey-mouse in performance. Took as much as 20 minutes to locate satellites. Went to my favorite online site and ordered a Holux bluetooth M-1000 GPS to pair with my mobile. Results looks good with bonus voice prompt.

..
Update: 11 July 2010. Negative experience with VPost.
Ordered the Oregon 450 after reading positive reviews. Purchased from Amazon online which includes free shipping. My intention is to get it shipped to Vpost USA address who will then ship to Singapore with attractive shipping rates at one third the shipping costs. Shipping direct would have costs me US$90 instead. The only con is slower transit time but I am prepared to wait.

Turns out to be a mistake. Vpost’s service is abysmal. First they refused to accept the shipment while its on its way. They claimed it contains batteries and is therefore considered as dangerous cargo even though Garmin do not ship batteries with their GPS. I have to write a letter twice to them together with description of the packing contents stating it contains no batteries. Next Vpost lost the shipment after USPS delivered it to them. I have to give them USPS tracking number thrice. Took them 2 weeks to tell me they do not have my shipment, giving me a one liner reply asking me to contact USPS myself. A note from them that they checked with USPS with no avail would have helped me claim a refund from Amazon. Disheartened I wrote to Amazon to help me trace my shipment with USPS and within 12 hrs Amazon wrote to me that it considered the shipment as lost and immediately refunded me. No questions asked. Amazon has my customer loyalty. Not for Vpost.

Geocaching

For those unfamiliar with Geocaching, its a treasure hide and seek game using handheld GPS. The treasure can be tokens in a little box with a log book to write your message. You can sign up free with http://www.geocaching.com to participate.

Treasure box

I put up my first cache in Ubin in 2006. The response was encouraging. but soon there were complaints about wild pigs, mozzies and being near ancient gravestones. Being new to the game, the treasure was put in an obvious spot and was soon gone.

I stopped soon after, plotting my next biggest and most convoluted cache for Ubin which this blog was originally created for. I never got round to it. But I am glad to meet a real life geocacher.

If you like to find Albert’s caches in Ubin, make sure you have insect repellents as mosquitoes hiding in the jungle will soon be all over you. Bring at least a mini-button compass with you. Its easy to get lost and wander in circles while the gps vainly tries to lock your location under jungle canopy.

Pulau Ubin abandoned prawn farms

Prawn farming used to be thriving in Pulau ubin. Inland swamps are parceled out with dykes. Sluice gates are constructed to control the flow of water.

Water pollution contributed to its demise. See further story below.

From GoogleEarth, one can see its scale by its tell tale remnants.

abandoned prawn farms

With GoogleEarth, we manage to plot our course by connecting dots of white roofs peeking through dense trees canopy seen under satellite. The course or path is then downloaded into our handheld GPS.

It led us first to a swing.

Finally a sweeping view from the remaining sluice gate, also a prime spot for bird watching.

Natural swamps are an important spawning grounds for fishes and with young fishes finding easy refuge. The sluice gates continues today as barriers. At low tide, the remaining fish are easily caught by fishermen casting fine nets.

The demise of prawn farms contd..
Other operators went in the big way into growing prawn hatchlings and using artificial feed. Their high density farming required plenty of electricity and fuel to keep the water aerated and filtered. But no man can mimic the power of God to turn deserts into fertile farmlands. The prawns could not survive to adulthood. Even fish farming did not work when holes appear on heads of the fish. Some even turn to sai kongs or taoist priests to purify their leased land.

sai kong

The Government’s decision to raise price of diesel was the final nail in the coffin. In the end lease were eventually given up back to the Government and building structures demolished. There was a Japanese entrepreneur in the late eighties who failed after spending $5 million and committed suicide when he returned back to Okinawa. Many Ubinites feel Pulau Ubin is cursed but even now it have not deterred people from seeking El-Dorado or being conned into it. If you are approached with a money making idea for Ubin, remember that the real God of Pulau Ubin is not Earth God or tu-di-kong but SLA who controls the fate of Pulau Ubin and who makes sure you cannot move an inch of earth or transfer any lease or build an English manor without their expressed permission.

Prawn Fishing at Ubin
The last lease holder at Marman river used the traditional method of harvesting prawns. A trawling net is placed where rushing water from outgoing tide flow through a narrow gate. The catch isn’t much, just one or 2 styrofoam box, enough for beers and food for a 3 men operation. The work is dangerous too as falling into the net means certain death from drowning. The method of farming is destructive as any unwanted fish or horseshoe crabs are either dead or trashed. We used to visit them at night curious to see what they have caught. But that was a few years ago when it was abandoned as catches became meagre.

You need to battle legions of mosquitoes to go prawn fishing there and if lucky get yourself a jumbo prawn after surviving the sticky heat and insect bites.

Its also a spooky place too. People have seen Na Tuks and one have seen an extra person among them. There was once a sai-kong who claimed to have cleared the area of wondering souls so they would not bother the living anymore.
