Hey John,
Hard to say about the Javad Victor Bracket holder, it's hard to see detail in the picture on the website. The type of mount is similar, utilizing the RAM balls. Seco makes a claw clamp with a 1" (RAMS "B" size) ball on it (Seco # 5200-160) that would be even nicer than the RAMS clamp that I am using, but it is twice the price and I didn't see the need for such a light object being held.
I do have to manually reconnect the Bosch every time I turn it off - I just leave it on instead. It would be great if it auto connected to the LS when I turn on the bluetooth in the Bosch, but that doesn't seem to be the case.
There seems to be two ways to connect to the LDM in JField. One works much better for me, but I am still experimenting as well.
First, tun on the Bosch and then turn on the bluetooth in it.
From the Home screen of the LS, tap the bluetooth icon at the top of the screen. At the bottom of the screen there are three buttons: Configuration, Accessories & Scan.
You can connect through tapping Scan, selecting the Bosch and tapping Connect, but I have troubles doing it this way and when in the Offset workflow it doesn't recognize the LDM.
Instead, tap Accessories, select the Bosch and hit connect. After it connects, you should see a new screen showing the different measuring reference points for the Bosch (front, back, 1/4-20 mount, etc. For my mounting, I select the 1/4/20 mount. If you tap the distance box in that screen, it will take a shot and display the distance which you could check if you want. Once you have this set, you can back out to the home screen and start measuring.
