Avocet Vertech watch
*mi...@ibm.net
I wanted to buy Avocet Vertech watch with an altimeter.
Upon a telephone inquiry at Avocet I was told that they temporarily
stopped their production due to a shortage of some chips.
I wonder if that's the real reason or not:
Didn't they discontinue the watch altogether?
Don't they plan to release a new, better model in the future? When?
Does anyone know?

of plastic holding the axes of the bracelet broke. It can't be repaired
(except maybe doing a dirty job with some glue). And the watch is leaking
too. And I've had it barely a year...
Also, thinking about that, I think there is a bug in the morning ring
software. If it is 'on' and you change the setting of the hour for the
beep, sometimes it won't ring. You have to turn it 'off' and 'on' again.
But I could not reproduce this problem for sure. Could be I'm just hard to
wake up.

I'll bet it's cuz those watches are terrible. My experience with the
gadget watch is:
1. If you want a watch, buy a watch. I prefer the analogue ones with the
tritium treated number marks.
2. If you want an altimeter, buy an altimeter.
3. If you want a compass, buy a compass.

You should have been at the K-2 warehouse sale last month! They
had a case of them that sat on the shelf too long and had dead
batteries, $5 each!
But I do seem to recall the chip being unavailable. If I
remember right, the chip was made for aircraft use and Avocet was
just a minor consumer of them.

Not really. I've had one (Avocet) for 7 years and it works just fine. I've

The watch works fine. The altimeter works just fine. The external compass
on the band works fine, too, and was cheap ($7).

The same thing broke on my watch. There were electronic glitches similar
to yours. The chip on the first Vertech I had was bad and the company
sent me a new watch. After trouble with the second one, I pitched it and
bought a Casio.

Oh, please...
Vertitechs are fine altimeters, though mediocre watches. In fact, I
prefer to wear mine on a lanyard or in a pocket. They are good
altimeters, though mine exhibits some drift with changes in instrument
temperature (on the order of 1m/degreeC), despite the temperature
compensation. Lastly: what compass?

Out of curiosity, which one? I just bought a Casio BM-200, but I'm
rather dissatisfied with it and wish I'd bought the Vertech instead.
This one isn't temp. compensated, and tracks cumulative gain AND loss,
which is a totally useless combination (what the hell am I supposed to
do with that information? So the thing reads "0 ft." again when I get
home from a ride...I needed a $60.00 "aircraft precision instrument"
to tell me that whatever altitude I gained on the way out would be
lost on the way back?)

Hey, look on the bright side- If it doesn't read 0ft when you get home, you know

Maybe try reading the owners manual. By the way, ALL electronic
altimeters are temperature compensated. If they weren't they wouldn't
work at all. Temperature compensation is either built into the pressure
sensor and/or provided through software compensation using an additional
temperature transducer. Avocet just does a better job of marketing the
fact they are temperature compensated.

It is a less than great thermometer, but it is useful never the less. I
think the spec was within 4 degrees F in the range from 32 F up to body
temp. I don't know what +/- 10% would mean on a temperature display. Lets
see, were at about 500 degrees Rankin, so that means +/- 50 degrees F? It
is easy to set and, when properly calibrated, it gives useful readings
while I'm riding.
Actually the biggest temperature error source for my Vertec is the sun.
When it is sunny, my Vertec's thermometer reads quite high, as you would
expect for a black object mounted (on my handlebars) in direct sunlight.

Nonsense. Casio made a big marketing splash with the alti-thermo watch,
which WAS temperature compensated. They even compared it to their old
ones, which were NOT.

The Avocet Veritech is not temperature compensated. I called the
ever since I recieved my new toy. They told me that if I was waring it
next to my skin it would read my body temperature near the surface of my
skin rather than the air temperature. "Oh," I said, "why?" Because the
wathc itself is designed to fit on the outside of a jacket or parka.
"Oh! ya mean like in all the pictures?" Yes, they said like in all the
advertisements.
I gave it some thought. I really don't need to wear a coat all the
time, I thought, because it gets hot sometimes. So how, oh how can I
fix this. "Ah!" It came to me. I made a "wristlet" to wear under the
watch. It has two purposes: 1) to shield my watch from my body heat, 2)
to hold my keys while I run O (yippy I like this line of thought). I
used an old piece of neoprean from a ripped-up wet suit. Didn't take
much at all. And now I can amaze and annoy my friends and colligues my
delivering the exact time and temperature at any moment in the home or
office.
Happy Toys!

Not the Casio Alti-Depth watch's altimeter -- I get a several
hundred foot elevation change in under fifteen minutes out of
the temperature change from wearing the watch on my wrist vs.
having it sitting on my desk top at 68F. If it's temperature
compensated in any way, it sure isn't very well done.

This thread is a wealth of misinformation. The "Vertech" IS indeed
temperature compensated. The temperature display shows you the temp
of the altitude sensor, NOT the air temp or your skin temp... and
they've made some attempts to keep the altitude sensor thermally
isolated from the air to minimize the swings they need to compensate for.
I talked to one of the design engineers at Avocet who argued with
marketing that the temp display should NOT be visible, since people
would misunderstand it. They do. It's a readout of what the compensator
thinks it needs to compensate for, NOT a readout of what your body
might be experiencing. The temp display is also +/- 10%, making it
even LESS useful than those little $3 zipper thermometers.

At least you know your watch, sorry, precision piece of equipment, is
accurate. I set my watch to zero at the beach and then spent half an
hour slogging up a steep hill side on the Isle of Rum, (Rhum). Looking
at the watch,I was told I was at MINUS 150ft??? Two questions here:
1. Is the watch knackered, battary was replaced in November,
2. Does the magnetic rock on Rum effect the watch that bad?
There were no major weather fronts moving across at the time and a
mates Casio was not effected. This is the second time the watch has lied
big time, once I was told I was 12,800ft high in Aberdeen, but that
turned out to be a flat battary.

Out of more curiosity, what the heck do you mean "tracks

either gain or loss, not both. So it must be a new feature that I

I own a Casio and use the cumulative gain/loss all the time.
Cummulative means the TOTAL amount of gain and loss for the trip. It
does not zero out. It adds all the ups together (hence: cumulative) Now
if you hike (I live in Colorado) in the mountains, you can travel as far
up and down as you can on flat ground and this feature is very usefull.
As far a temp. compensation, I tested both the vertech with temp comp
and my casio without temp. comp. and found that the casio did a better
job of maintaining correct readings as long as I kept the watch on my
wrist. Over a period of a week I would go to the local airport where I
was allowed to go into the air tower. I set both watches for the exact
altitude. I would then return in 1 or 2 days and compare the results (
made the adjustments for barometric changes). My casio is the older
model and only has altim and barom. so you MUST first put the watch on
for about 15min. and then set the correct altitude. This allows the
watch to warm to your body temperature and then it will be ok. Do you
know what RTFM means (read the /;;'';'; manual) as there is a lot of
very good information there.
Here is a post done by a person who also tried both watches and he had
the newer casio.

Is your watch the Casio BM-200?
I have a Casio watch which tracks each independently, ie max gain, max loss,
total gain, total loss, and cumulative gain/loss.
The Vertech only tracks total gain/loss, but not both.

Casio Alti-meter. There are no other numbers/model # on the face of the
watch. On the back, in small letters, is "734" in a box, and AW-330 next to
it.
The watch has 3 memories which each store 5 values: total up/down, total up,
total down, cum up, cum down.
This one was on sale at REI about 1-2 years ago for $50.

I must have missed this response, so I'll reply here...
More likely, the feature on my watch is on older one that was phased
out when the mfg. figured out how useless it is. What I mean by
"tracks cumulative gain and loss" is just that...when you go up, the
watch records how far up you've gone. But when you go down, it
subtracts your altitude loss from the total. In essence, if you were
to set out on a circular route, when you return to your starting point
instead of giving separate readings for your cumulative altitude gain
and your cumulative altitude loss, it combines them into one reading,
which of course is "0".

Delta. Think delta. Don't think absolute. If the temp changes 10 deg F,
the display will show somewhere between 9 and 11 degrees change.
There is an ADDITIONAL error for the absolute spec, but that can be
calibrated out at whatever temp you choose (which is why thinking
absolute temp is wrong-thinking).

It would be hard to beat the CASIO PATHFINDER watch. Functions include:
Altimeter, Barometic Pressure, Temperature, 5 alarms, Compass, Large
memory for recording elevation and temperature changes at 15 minute
intervals for 12.5 hours, day, date, dial light and two stop watches. I
use mine constantly when hiking and give it an A for usefulness.
Hopefully they will build the above watch with a GPS next!

You know, I'm growing tired of people telling me to RTFM. Did you
read my f#@%ing post? I purchased the Casio BM-200. Not "a" Casio.
Not a recent model Casio. The Casio BM-200. Which according to TFM
tracks cumulative gain AND loss...not cumulative gain and cumulative
loss. This means it zeros out when you go up, then go down. Trust
me, I've not only read about it in TFM, I've witnessed it first hand.
Now, if you've got a Casio BM-200 and a FM that says otherwise, post
the instructions on how to make it display cumulative gain, because
that very good information seems to have been omitted from mine. I
eagerly await this revelation!

I think features of the Vertech are being overlooked in the cumulative
altitude discussion. The Vertech has a patented system of rejecting
"noise" that invariably enters into such readings. When hiking over
rolling terrain (or Bicycling with the AVO50) of 3-5 meter bumps,
these changes will not be added to the total climb. Without this
feature, hiking up a 3000ft ridge while crossing no valleys >10 m, a
larger value would be accumulated than was actually climbed.
This noise rejection is essential to accurate accumulation of rise or
fall, so that when hiking in the flat, no gain or loss is recorded.
This is more important than at first meets the eye. When monitored on
a test course, the effect becomes obvious immediately.
The Vertech also counts ski runs by altitude gains greater than a lift
sag, also making using this patented noise rejection scheme.

They patented hysteresis? Amazing! The manual just says the watch
ignores changes in altitude until they reach 30 feet. Engineers have
been doing that sort of thing for decades if not centuries.
In my mind, the only reason to own an Avocet (and I do) instead of
a Casio is the climb rate indicator which shows both average and
a weighted average (10 min window). Very useful for deciding how
tired you are (if you are feeling tired but going slow, you can
decide to turn around, or if you are racing up the hill too fast
you can pace yourself).

You are right. I have the Casio "Alti-Meter" AW330 watch (costs $60.00,

I'm interested in putting together a city bike to use for commuting around the city. Before I can
get started however, I need to do something with the frame. I picked it up from a personal
framedealer (for a discount) without ANY paint or finish. It's just simply steel tubing (eh, probably
a cro-moly) with a surface that resembles the touch of steel pipes one might find in a house.
Anyway, I'm not interested in painting the frame (not only do I not have any friends at the local
automotive body shop, nor is there one in the area; but I like the look of the unpainted frame),
but I do think that I need to coat it with something in order to protect it from the elements. Does
anyone have any suggestions? I was thinking about using steel wool to rough the surface a bit
and then coating it a couple of times with clear Rustoleum.
Sorry if this is a popular question, but I couldn't find any help in the archives or the faq.
Thanks.

You can coat the frame with Frame Saver, available from Rivendell

The one that got me is the the Avocet doesn't have a light. Do they
expect people to carry a second watch for night use?

Say, I've always wondered about that... if you're doing anything other
than loafing around the tent, what possible use is a history of pressure?
Isn't that the same thing as altitude? So the "trend" will be useless
unless you stay at one altitude for the whole 18 hours!

"Noise" that invariably enters into such readings... We used to find our

I don't think you understand the purpose of the hysteresis. If you
ride a bicycle from town A to town B that are at the same elevation,
riding over RR overpasses and underpasses does not constitute what is
generally considered climb. he same goes for small bumps in rolling
terrain. Therefore, it is not a sensor problem, but rather a method
o extract the significant elevation changes from the insignificant.
The Vertech watch uses this technique to count ski runs, by detecting
uninterrupted climbs with insignificant descents, those caused by lift
sag between support masts.
