Eugene, If that is the case, then yes I would like to be part of the early release program. You may want to talk with Michael as he may have already placed us in the program. Thanks and have a great day.

Hi Eugene, we are looking forward to using the J-Mate. Please let us know how the early release program is moving along and when we can expect the JMate to be shipped to costumers like myself that have already signed up to receive the J-Mate. Thank you and have a great day.

I think a date is difficult to give at this time. It won't be released until the PLS team is satisfied that it is usable.

Thank you, excellent. Keep up the good work J-Mate team. We are rooting for you guys and looking forward to owning a fully functional J-Mate unit when they become available to the rest of us.

I am having issues trying to get my J-Mate to find and or track the target on the my LS, what am I doing wrong?

Hi Brad,

We're preparing a number of tips and recommendations in the device manual, but the document is not released yet as well as the device. Here is a brief checklist of what should be kept in mind and checked in case of tracking difficulties:

• For J-Target: Note that the color selected in the parameters is the pattern color, not background. It may be little confusing because the “White” J-Target is the dark one;
• For J-Target: Note that target size and coloring are independent. Thus, make sure to check both even if you use the standard targets. When using our standard targets, select “White” shape along with the built-in “On Triumph-LS Back” size and “Black” with the external J-Target “On Pole”;
• For J-Target: Also notice the so-called “quite zone”, which is a clean background (either black or white) area around the pattern itself. It may look like a decorative border, but it’s not. The quiet zone is a necessary part of the recognized target, so make sure it’s not covered with some obstacles during your work;
• Keep in mind that a target should occupy a noticeable part of the camera image. When the target becomes too small, you should zoom in and when it’s too big for convenient fitting – zoom out;
• Focusing is essential, especially for J-Target. Always be sure you have correctly focused the camera;
• Generally, it’s better to have underexposed image, then an overexposed one, but it’s not always true and may depend on the surroundings conditions. Sometimes it’s worth trying to make an image a step darker or brighter if you have a trouble times recognizing the target. Once a target is found, J-Mate will try to maintain correct exposure and focus, but you should help him to start;
• Pre-digitized image technique is not required in most cases, bit don’t forget it exists. Sometimes it can help. Be sure turning it off and resetting the threshold when it’s not required anymore;
• Glares are your enemies. There is no universal solution, but when there are glares on the J-Target edges or Zebra sides, these are the first suspects to be ridden off in case of recognition problems;
• Zebra has a wider working range of distances and lighting conditions, while J-Target is less susceptible to false detections. J-Target on pole is more reliable than the one
on TLS+ back;
• Zebra, being the most reliable target, is considered as the default target if you do not have any specific reasons not to use it;

Thanks Mikhail! Since the Zebra is considered to be the default would I be better suited to purchase one, but I do not see it on the accessory page on the website?

Hello all,
Any updates on the J-Mate's development? Many of us are looking forward to its release. And have the Thriumph-LS Plus upgrade and T-3 ready looking forward to the J-Mate's release to have the JAVAD's Total Survey System Solution. I see all those J-Mate's icons on the the T-LS Plus and wonder what great things they can do. Every time I survey a Strip Mall I wish I already had the J-Mate with me so I can locate the ADA H/C Ramps, sidewalks, columns and building corners under the building's front covered sidewalk. J-Mate Team Keep up the good work! We are rooting for you to get the J-Mate where it needs to be for release!

I got a good tip for you on building corners that works real good.
Do two offset shots with a distomat. Not the white box with compass - It simply is not accurate enough.

I record two shots in precise topo at about 90 degrees for each building corner.
After each shot is taken, I measure with the disto to the corner (6.4 for example)
Then I code it BX C6.4
Go do the same thing for the other side of the same corner.

I use Carlson so the code C will draw a circle from the BX shot with a 6.4 radius
Second shot BX C10.7

Your corner is where they intersect.
My code BX does not draw a node with elevations so the circles all have zero elevation to keep things simple.

I always locate at least 3 corners on a bldg in case one of the topo shots is bad ( It happens albeit rarely - it does happen though)

I especially love this method when there is a big bougainvillea bush or cactus along one of the long walls - LOL

Thank you John!, that is a great tip to locate building corners. I have a distomat and have never used it for locating building corners in this manner. I will give it a try. I usually follow the procedure you recommended but I use the level rod instead of the distomat to measure the offset distances. I set the rod flat on the floor aligned to the building corner and place the T-LS at say 10 ft and 15 ft offsets on top of the level rod. Then at the office i draw a line between the two shots and place circles with R=10 ft and R=15 ft and draw a line between the two points and extend the line to where it intersects with the circle(s). Then average the error in between where the line intersects the two circles.
I figure another way to do it could be to use COGO on the LS to obtain the building corner using the two offset points and distances. Of course, when we get our J-Mate we won’t have to go through all this trouble. We are looking forward to getting our J-Mate unit

I have finally had some time to get my J-mate out and test it out. after receiving the Zebra Pole I am still not able to get the J-mate to find the zebra pole and track the target?
