Company Overview
Tasman Instruments is a small company located in Belgrave Heights, Victoria, Australia that is owned and operated by Malcolm Crampton.  The Tasman V2000 variometer has earned a great reputation for ease-of-use and quality and is very popular around the world.  The averager on the face of the unit and the built-in speaker are two reasons for it's great success.  To learn more about the V2000 and accessories please take a few minutes to watch the Tasman Overview Video.  The FP10 Flight Pack is the newest addition to the Tasman family of products. 


News
June, 2010 - Tasman announces the V2000 Variometer.  The V2000 is functionally identical to its predecessor - the V1000.  The only difference is that the V1000 had a more colorful control panel and function buttons.  Some customers thought it wasn't "classy" due to being "too colorful".  The V2000 addresses that concern very nicely with its simple black and while face and buttons.  It looks great in any instrument panel.


Tasman Overview Video
If a picture is worth a thousand words, then a video with sound must be worth a million.  Below is a 6 minute overview of the Tasman V1000 variometer and accessories.  It allows you to see and hear all the functions of the V1000.  It is a great way to see if it is the right vario for your glider.  Or, if you already own one, it is a good refresher course on how to use it.  If you find it useful then please buy from me.  The video does not include the FP10.
Note: Since the V2000 is functionally identical to the V1000, the video applies completely to the V2000 as well.

Example System Utilizing the FP10 Flight Pack

Tasman V2000 Variometer, Tasman FP10 Flight Pack and EW Avionics microRecorder
This system is a full featured flight computer system.  It does everything that the all-in-one flight computers can do.  The EW microRecorder is an IGC approved flight recorder.  The Tasman V2000 is an audio variometer with averager.  The Tasman FP10 Flight Pack is a flight data module that adds vario and true airspeed data to the GPS data so the PDA can display speed-to-fly information and calculate accurate vector wind data.  SeeYou Mobile can also use the vario data with its Thermal Assistant.  The best thing about this system is that it is modular.  You can start with the Tasman V2000 and add the FP10 and other items later.  Or start with the EW microRecorder and PDA and then later add the V2000 Variometer and FP10 Flight Pack, or...

V2000 Tasman V2000 Variometer
Note: The V2000 is functionally identical to its predecessor - the V1000.  The only difference is that the V1000 had a more colorful control panel and function buttons.  Some customers mentioned that they thought it wasn't "classy" due to being "too colorful".  The V2000 addresses that concern very nicely with its simple black and while face.  It now looks great in any instrument panel.

Overview
The Tasman V2000 vario is a very nice product.  It is a solid state product with no moving parts.  That makes it very reliable.  It uses pressure transducer technology and does not need a flask so it makes for a compact installation in the sailplane.  It features an audio output so you can keep your eyes outside the cockpit and and averager so that you can determine the strength of your current thermal.  It has been one of my most popular electric variometers.  I think the main reason it is popular is that the speaker and averager are built-in.  Some competitive products have external speakers and averager displays which make installation much more time consuming.  However, if you prefer an external speaker with the V2000 you can purchase one as an option.

Averager
If you have never flown with a vario that has an averager, you are in for a treat.  Without an averager it is difficult to determine how well a thermal is helping you climb.  Peak indications on any vario can be misleading.  The averager gives you a better estimate of the actual climb rate.  It is especially handy in weak thermals as it helps you determine when to leave the thermal.  I've experienced circles with climb on one side of the circle and moments of sink on the other side (we've all been there).  It is difficult to tell whether you are going up without the averager.  At times the averager has confirmed a 1/2 knot climb - which is plenty when you are low.  Other times the averager has confirmed 1/2 knot of sink - it was time to move on.

Overview
This Variometer is designed to satisfy a need for a product that utilizes the most current technology to produce the best possible performance at the lowest possible cost.  The Variometer has at its core a semiconductor pressure sensor with a digital output which can resolve some 32 million separate codes. This results in a Variometer which can measure only a few inches of altitude change without a practical upper limit in altitude. With such fine measurements possible, a fast sample rate results in a Variometer which is responsive and accurate.  Digital signal processing allows the user to set the Variometer response time in fine increments, and select from a range of display and audio vario options.  An important side benefit is that the parts count is minimized and so the cost and size of the final Variometer is reduced.  The Variometer accommodates and expands on all the most important functions of a standard vario, i.e. vario audio, current lift/sink rate, and includes the primary feature of the 20 second Variometer average simultaneously displayed - all in the same small package.  This Variometer is designed to give years of trouble free service. (3 year warranty).

Operation
Simple controls with only two buttons which control the Variometer audio volume, read the battery voltage, and allow access to setup values if required. With the 20 second Variometer average continuously displayed and a warning signal for the battery voltage all on the screen, no other controls are required.

Audio
Considerable effort has gone into developing an audio vario tone and pattern to convey to the pilot the maximum information without being intrusive or annoying. The climb tone consists of a series of beeps whose pitch, rate and volume increase with lift rate, somewhat musical in effect. The sink tone has a (fixed) threshold at -2.5 knots and is distinct from the climb tone in that only the pitch changes and the rate is constant. The effect can be compared to a bell ring. The vario audio response is non linear to give the greatest resolution at the lower climb rates. At climb rates below about 2.5 knots, a change of 0.1 knot can readily be detected in the audio tone. This gives the maximum amount of Variometer information to the pilot at times when a Variometer is most important i.e., when trying to recover in weak lift, or to extend a flight on winter days or during wave flights. This maximizes the pilots achieved climb rate without the need for visual reference to the Variometer for confirmation of the current climb rate.  A concise audio is essential to maximize the lookout time for the pilot.

3 Sink Tone Options
The sink tones below can be selected in setup mode.

  • No Sink Tone
  • Sink Tone Deadband, no sink tone from 0 to -2 knots (or 1 m/s).
  • Sink tone for all sink (no deadband)

User Feedback
Since deciding to sell Tasman varios I've asked pilots what they think of their Tasman.  I've been very impressed with the positive feedback from every user.  I have 2 V1000 variometers in the DG-1000 I fly.  The Minnesota Soaring Club (the club I belong to) has V1000 variometers in every club owned sailplane.

Two Seat Glider Installations
Tasman offers a repeater for use in 2 seat gliders.  However, they don't cost much less than a standard vario and they have less resale value.  They can only be sold to owners of 2 seat gliders.  I recommend buying 2 V2000 varios for 2 seat gliders.  That way each pilot can adjust the vario to suit their needs and resale value is as high as possible.

RDV100 RDV100 Remote display for use in 2 seat sailplanes
This is a low cost way to add a repeater to the 2nd seat in a 2-seat glider. The repeater does not have any controls.  It is a display only.  It fits into a standard 57 mm (2 1/4 inch) instrument hole.

Some owners may prefer to pay the extra $380 to buy a 2nd V2000 vario instead of the repeater so that each pilot can adjust their vario to their preferences.  Also works great with the Tasman V1000.

FP10-s5V FP10-s5V Flight Pack - Flight Data Module
The FP10 Flight Pack is an innovative new product which can turn a Tasman V2000 Variometer into a speed-to-fly variometer when used with a PDA running soaring flight software.  The speed-to-fly information is sent to the PDA and displayed on the PDA's screen (not on the face of the Tasman V2000).  The FP10 has built-in Pitot, Static and Outside Air Temperature sensors which allow it to send barometric pressure and airspeed data to the PDA.  It also passes GPS data from an external GPS (not included) and vario data from the Tasman V2000 variometer on to the PDA. If you already own a Tasman V2000 variometer and use soaring flight software on a PDA then the FP10 is a low cost way to upgrade to a speed-to-fly variometer with accurate airspeed, pressure altitude and vector wind data.  If you don't already own a Tasman V2000 variometer then the combination of V2000 and FP10 is less expensive than other speed-to-fly variometers.  I also like the modularity of the system.  You can start with the V2000 only and upgrade it to a speed-to-fly variometer by adding an FP10, PDA and GPS at a later time.  At that point is offers all the flight data found in much more expensive flight computers.  The only feature missing is that there is no audio sound for the speed-to-fly.  It is displayed graphically on the PDA only. 

The FP10-s5V efficiently converts 12V power from your glider battery into 5V power for the PDA.

Compatible with All Goddard soaring data cables!
The PDA and GPS connectors on the FP10 and FP10-s5V are identical to the connections on the Goddard  PS-5a power converter.  That is great because it means that all the standard soaring cables in stock at Cumulus Soaring, Inc. will work great with the FP10 and FP10-s5V.

Data Sent to PDA

  • GPS Data - All GPS Data (GPS not included) from an external GPS is passes through the FP10 to the PDA.
  • Variometer (current value) - Used by the Thermal Assistant in SeeYou Mobile and other soaring software to help you find the center of the current thermal.  Also used for thermal history graphs on the PDA.
  • Variometer Average - Displayed on the face of the Tasman V2000 Variometer and made available to the PDA software.
  • True Airspeed (TAS) - The Outside Air Temperature gauge and barometric pressure sensor make it possible to calculate True Airspeed.  The PDA can use the GPS data (ground speed) and True Airspeed data to calculate accurate vector wind speed and direction.
  • Barometric Altitude - Sent to the PDA and used to calculate the True Airspeed.

Compatible Soaring Flight Software
The soaring flight software listed below uses the flight data supplied by the FP10.

  • XCSoar
  • Soaring Pilot
  • SeeYou Mobile (click on image below to view larger version)

Included with the FP10 Flight Pack

  • FP10 Flight Pack Module
  • Data Cable for connecting FP10 to V1000 Variometer, 6-wire RJ cable
  • 2 Tubing Tees
  • Installation Manual

Compatibility
The FP10 Flight Pack must be used with a Tasman V2000 or a Tasman V1000 with a software revision of version 3.2 or higher.  This revision has been supplied since late 2006.  All V2000 variometers were built with this version - so V2000 units do not need an upgrade.  Upgrades for V1000 units are available here: V1000 Upgrade.

PK312 PK312 9V Backup Battery Pack
This optional battery pack holds a 9 V Alkaline battery that provides at least 12 hours of operation for the V1000 or V2000.  The V1000 or V2000 automatically and seamlessly switches over to the 9V power from the PK312 if 12V power input is lost.  The audio still functions, but the maximum volume is reduced from 5 to 3. 

This device will supply the Tasman V1000 or V2000 variometer with automatic battery power backup in the event of failure of the main supply. It can provide a "get home" fail safe facility or simply allow the continuation of a flight that might otherwise be lost. It operates by sampling the load current and switches to the best power source by a latching relay. The LO BATT signal is displayed when operating from under 10.5 volts. No standby power is consumed by the PK312.

Simple Installation
The V2000 is delivered with a power cable that plugs into the back of the V2000.  The PK312 includes a cable that is to be connected between the PK312 and the V2000 - into the connector where the V2000's power cable would normally go.  The V2000 power cable is then plugged into the 2nd power connector on the PK312.  No soldering or wiring is required.

V1000 Upgrade Required
A hardware and software upgrade is required to all V1000 units with serial numbers before 060519 to be compatible with the PK312.  The hardware and software changes were necessary so that the V1000 can automatically switch itself off to conserve the battery if no altitude change is sensed over 2 hours.  A single 9V battery should last an entire soaring season if it is not used in flight for extended periods of time.

TB32 TB32 Echo, Recorded Sound Alarm
Echo is a self contained digital recorded message alarm.  If you have ever seen a fiberglass glider slide down a hard surfaced runway on its belly with the gear up you will know that this item is an excellent investment.  It is a shame to put a flat spot (or worse) onto the bottom of a beautiful sailplane.  Certainly, no product can guarantee that the pilot will hear it and follow the directions when busy setting up a landing.  However, this product can help you remember to lower the gear, hopefully early in the landing pattern, or before entering the landing pattern.

Hear how it sounds in the Tasman Overview Video (toward the end of the video).

Included in the unit is a microphone for recording a message or sound up to 14 seconds in duration.  The message is retained without power connected and plays continuously when power is supplied

Mounting Options
Fits into a small 57 mm (2.25") instrument panel hole.  Also includes tabs for surface mounting.

Dimensions: 59 x 59 x 32 mm (2.32 x 2.32 x 1.26 inches)

Echo is ideal as a "wheels up" alarm or in any alarm application.
The voice message ensures attention even during high workload or stress situations.

Operating power supply: 7 to 18 volts at 100mA. 9 volt battery and clip supplied.  Note: The included 9V battery is intended for use when recording the voice message - not for use in the glider.  Most installations connect the Echo to the glider's 12 volt power supply.
Standby power drain: Zero

Example message for gear up warning: "Landing gear is up.  Lower the landing gear."

TB32 Echo Installation Instructions

Landing gear and airbrake switches are required but not included.  I offer some very nice, small switches on my Miscellaneous page.  I recommend using the magnetic reed sensors if possible because they are non-contact friction-free devices that will not interfere with the objects they are sensing.  However, magnetic reed sensors require that a target (magnet) is mounted on the item to be sensed.   Mechanical lever sensors sense the actual item rather than a magnet.

Switch/Sensor Installations
The idea is to use 2 switches in series that allow current to flow when the airbrakes are open and the landing gear is not down and locked.

  • Airbrakes Locked Sensor
    The goal is to have current flow when the airbrakes are not closed and locked (fully forward)
    • Use a normally closed switch at the forward (airbrakes locked) position
  • Landing Gear Down and Locked Sensor
    The goal is to have current flow when the landing gear is not down and locked.
    • If the switch is mounted in the gear down and locked position then use a normally closed switch (recommended).
    • If the switch is mounted in the gear up position then use a normally open switch.

Recommendations
The goal of this product is to help pilots realize early in the landing pattern that they do not have the landing gear down.  For example, if the pilot flies the entire flight with the gear down and then enters the landing pattern and raises the landing gear while performing his landing checklist on the downwind leg of the landing pattern.  A good landing checklist has the "Undercarriage" listed before the "Airbrake Check" (be sure to open the airbrakes) so that when the airbrakes are checked the pilot will hear the landing gear warning if the gear is not down.  Certainly there is a lot going on while in the landing pattern.  It is highly recommended that the landing checklist be completed on the downwind leg of the landing pattern - not while on final approach.  Some accidents have occurred when pilots realize their landing gear is up just before touchdown and try to lower it at that point.  If your landing gear is not down when you are on short final you should leave it up and land the glider as gently as possible.  A little damage to the glider is highly preferable to major damage to the pilot and glider.  Hopefully this device, along with a properly executed landing checklist on the downwind leg of the landing pattern, will help pilots get their gear down early in the pattern.

V1000-Upgrade Hardware and Firmware Upgrade for V1000 Variometer

The new firmware version offers several new features:
  • Compatibility with the PK312 9V Backup Battery Pack
    A hardware and software upgrade is required to all V1000 units with serial numbers before 060519 for compatibility with the PK312.  The hardware and software changes were necessary so that the V1000 can automatically switch itself off to conserve the battery if no altitude change is sensed over 2 hours. 
  • New Sink Tone
    The sink tone now gets lower in pitch with larger sink rates.  The previous versions had a sink tone that increased in pitch with larger sink rates.  The climb tone remains the same as it has always been with increasing pitch with higher climb rates. The sink tone can be disabled if desired.
  • Compatibility with FP10 Flight Pack

The upgrade must be done here in my office.  The price includes the cost of the new firmware chip, installation labor (circuit board change) and testing.  The price does not include shipping back to you.
