    New comer: Ascen GPS watch (Comprehensive review with pics)

    GPS watches have always amazed me. The first in history was the Casio SatNavi watches, namely the ProTrek PRT-1 and PAT2GP. You had to wait for ages to get a GPS fix, and pray your battery lasted during the wait. Those were the days.. Then came the Suunto X series, which are "bulky", plastic, fragile and unreliable. The bezel and strap issues were stubborn and never been resolved by Suunto. However, I still use my X9i's and X10 sometimes for hiking and cycling. The X10 has a newer machinery inside, but still feels like a toy watch, though it is the most densely complicated device I have ever owned. I routinely check if new GPS gadgets are commercially available. My latest find is the Ascen GPS 300 watch. Unfortunately the Ascen site and user's manual is Korean, and although I tried hard, I was not able to translate them into English using google's translate service. However the manual is short, and you can easily figure out the watch's menu system and its functions yourself. It only took one evening for me.

    UPDATE (Jan, 13th): An identical watch is found on internet by Sedi, and the webpage has an English manual for the watch:

    http://api.viglink.com/api/click?for...6%2F&title=New comer%3A Ascen GPS watch (Comprehensive review with pics)&txt=Discover GPS - GPS Watch | Tech4o&jsonp=vglnk_jsonp_13264523165042

    I bought the watch through eBay, it was $160 + $7 for shipping, and it arrived only in 5 days from Korea to Turkey. The seller is both fast and kind, I highly recommend him:

    Smart GPS Watch GPS300 Tracking watch Waterproof Sports Watch | eBay


    The Ascen GPS 300 sports watch.

    It is designed and made inTaiwan by Ascen Ltd., a GPS manufacturer. Released as a sports watch, it can also easily be a dress watch, because it is elegant and it feels high quality. Comes in a nice looking factory sealed package which includes the Korean manual, a CD which has the same manual's PDF version and the "GPS master" software, and a USB charging snake mouth cable.








    The watchband which is continuous with the bezel is black resin. The glass is mineral. It is not heavy, only 55 g, is 30 m water resist, wears comfortably. It somehow feels like a 6900 series G-Shock on your wrist. It is not big like the Suunto's. Actually it is smaller than our beloved Protreks... Side by side with Suunto X9i, GW5000 Gshock, and PRG240t:










    The plastic back has the metal/gold connectors for the snakemouth USB connector which uses standard USB for data exchange and charging. One full charge gives you 1 year of time keeping (no GPS and no compass or backlight), or 8.5 hours of continuous heavy GPS usage and navigation functions. This is the best in GPS watches I ever owned. The nearest one, Suunto X10 has a few months of time keeping and 6 hours of GPS, which is a bit short for a day spent outdoors.

    The normal timekeeping mode screen has high contrast and is readable under any lighting condition. Backlight is very dim and you can only see that it is there only in pitch black darkness, which is the only condition you will need a backlight, because of the high contrast of the nice graphic screen. The watch has 5 buttons, two on left, three on right. The buttons are almost level with the bezel and it is a pleasure to press.

    Now let's see what it can do. You have 5 independent alarms which can be set either Mon-Fri, Every day of the week, or any day of the week. The alarm sound is very high, way higher than any Casio, it made me jump out of bed this morning and lasts for thirty secs. Dual time can be set half hour intervals, but no city codes, but you have the home city time on the same screen. We have the timer which can be set down to seconds. The stopwatch functions are sophisticated and are combined with sports profiles, which I am still trying to figure out. You have a choice of two different operating modes: Navigation and Workout. Navigation screen has an arrow which shows you where your waypoint or track is, and many fields that tells you your speed, distance, time to go etc. Workout can be chose as any of a few different activity types, which are cycling, hiking, sailing, running and user customized modes. All thse activities have three individual pages that can show any data you wish the watch to show. That means you can customize any data on any page for that activity. The data types are time of day, calories, speed, time elapsed, pace, heading, distance, altitude, max speed, avg speed, lap no, lap distance, heart rate parameters, and many more... Finding your way around menus are very easy. Navigation function mainly takes you through prerecorded waypoints, backwards or forward on your recorded track, or lets you record a track or a waypoint. You have ten paths that can hold 99 waypoints each and about 48000 track points to record. I am still trying to learn using them properly. Cold start of the GPS is very fast, never more than 40 secs. Hot or warm starts are almost instantaneous. It is highly sensitive, works in the car or at home near the window. Compass works very efficiently, way better than my protreks or suuntos. I can rely on it during my mountain hikes. You always have the GPS altitude, which is quite accurate (at least more accurate than any Core or Protrek..!) on any screen you'd like. The GPS master software that comes with the device is a complicated piece of software that connects your watch data with google earth and has other advanced archiving functions. You can plan ahead a track in the mountains using google earth and upload it to your watch and realize it the next day. The time of day can be set to be updated with every GPS fix. It is better than an atomic watch. The watch can be turned off for power saving purposes (it still keeps the time and your setup and navi data). Here are some screen samples:





















    All these for 160 dollars.. It's a steal. I liked my new GPS watch a lot. I strongly recommend it to GPS fans, gadget freaks, cyclists, hikers, runners. Of course carry other professional navigation tools with you during outdoor activities. Thanks for reading.

    Great review and a very interesting watch, good and tactical looking too. Neiter too tall nor too big and one year battery life without recharge and GPS sounds amazing. Is the backlight reversed? Any chance of a nightshot?


    cheers
    A short Tutorial on „How to use and calibrate a Casio Altimeter“:

    1. Attach a string to your Casio AB(C) watch (feel free to use any length)
    2. Abseil the watch into an Abyss until you hold the string’s end between your fingers
    3. Get the watch up again
    4. Use a measuring tape to measure the string length
    5. Success! Now you have carefully calibrated the Altimeter
    6. Important!!! The Altimeter Lock will stay enabled, unless you shorten or lengthen the string

    Thank you. Here are some "night shots":

    A little more exposure, but this is brighter than what I actually see (enhanced):



    This is GW5000 as I see it (no enhancement):

    Thanks Rigel,

    positive displays with negative illumation is such a great thing which I prefer by far over positive illumination. The lume on your GPS looks very similar to that of my Tech4o and Timex's, rather subdued which is great to retain the night vision, but otherwise bright enough to clearly see everything - perfect. Damn, now you really got me hooked on this watch....

    Re: New comer: Ascen GPS watch (Comprehensive review with pics)

    Thanks for the review Rigel. I am actually looking for a do-it-all watch for timing different kinds of workouts and to help me navigate as I travel a lot. I have been researching ABC watches, but honestly most ABC watches have some of the features I am looking for, and a lot of features I'm not looking for. I had completely forgotten about GPS watches until I red your review. This looks like a very pragmatic watch with a simple easy-to-read display, and packed full of features that I will actually use. A compass, GPS navigation, excellent battery life, and a sophisticated stopwatch with customizable workout modes! If it truly works as it should and is decently rugged, I think you found my next watch!

    I do have a couple of questions.

    1. In your review you mention "heart rate parameters". Does this watch receive a signal from a heart rate monitor, or does it simply display generic heart rate parameters based on age/weight/etc.?

    2. Does the watch display elevation (altitude) information? Certainly the GPS signal provides elevation data, but not all GPS receivers display it.

    3. Would you mind keeping us updated on the watch's performance as you put her through the paces?

    Thanks again...my finger is on the trigger for this watch for sure!

    I answered my own question #2 after reading through your review again. So it does have GPS altitude....awesome!

    Rigel,

    I almost forget to ask: how long is the timer and the stopwatch mode - both 24 hours or even longer? Thanks in advance

    Hey time.addict,

    I still keep the Ascen on my wrist, even in the shower. It doesn't feel any different from a G-shock. As I drive, I check the speed, the elevation and distance to home (try this at your own risk :). I wish it had the following: the "satellites" page (the strength of connection, available sats etc), heading according to GPS, local sunset and sunrise times. I emailed the Ascen Inc for an English manual or a .doc version of the .pdf manual file so that I can translate it using translate.google.com, still waiting for an answer.

    Under the "Settings" menu item, we have the HRM (which, I guess, stands for heart rate monitor), and in it there are the on/off, HR zone, Pairing functions. HR zone is about different profiles of exercise/calorie expenditure relations including "health", "fat burn", "aerobics" and "custom" settings. When Pairing is activated the watch starts scanning for a chest strap heart rate sensor wireless signal. I dont have the slightest idea of what that chest strap is. I checked the producer's website with no result for a heart rate sensor device. I'm not sure if Garmin, Polar or other chest straps would work. Heart rate parameters to use on the sports activity pages are: HR Avg, HR Max, HR Min, HR, HRZ Abv, HRZ Blw, HRZ In. Since I don't have the HR strap, I cannot comment on these params. Under system setting menu, it expects you to enter your birthday, weight and gender. I am sure it uses these values for calculating the calorie etc.

    Yes, you can have the altitude value wherever you wish on any of the activity pages, as I told you before, data fields are utterly customizable. Altitude data is updated every second according to GPS computations, just like speed and distance parameters. For it to be accurate you must be locked onto as many satellites as possible. As a general side note, though 2D accuracy is huge for civic GPS, vertical accuracy is somewhat less. But as opposed to barometric altimeters, readings are free from effects of changing weather conditions. You don't have to calibrate the altimeter before you start a journey into the wild. After many years of GPS use, I can confidently say that the error range is below 25 meters at worst. I live at the sea level and I commute to work every day near the coast. When I am a few meters near the sea, if I read a "-6 m" or "+15 m" on any of my many GPS devices, I'd get concerned and give the device a "reset". I calibrate my Protrek watches according to the GPS altitude at the start of a climb, later on I use the Protrek.

    Hope this helps.

    Hi cal.45,

    The countdown timer can be set to 99 hours 59 mins 59 secs as a maximum. Alarms and the timer have different tones. The timer setting resolution is 1 sec. The stopwatch is available in workout pages as "LapTime". Its resolution is 1/100 secs for the first hour, then 1 sec for 99 hours, 59 mins. You have endless number of laps, which are individually stored for later use on "GPS master" software on PC to evaluate your performance, but you have the workout time running for the whole activity with the same resolution specs.


    A few updates:

    ** The glass is mineral according to the producer's website.

    ** The battery life with GPS on is 8.5 hours.

    ** The producer is located in Taiwan.
