Since Fat Shark brought out the Transformer SE Binocular Viewer both the Transformer Full Panel Viewer and the Binocular Viewer have been put on sale. The Full Panel Viewer will display 1280X720 while the Binocular Viewer splits the 720 in half for each eye piece.
I purchased the Transformer Full Panel Viewer discount package from getfpv.com. I recommend these Li-ion 18650B batteries to power the Display Viewer and this HDMI cable to connect the output of a laptop to the mini input of the Display Viewer.
Since my up close eyesight is pretty bad I could not focus the full panel with the included lens. My solution was to purchase a set of magnifier lenses and an extension for the Full Panel Viewer display.
The combination of the highest power magnifying lens (3.5 power) and the display extension has allowed me to focus the Full Panel display without any trouble. After removal of the “U” shaped mounting clip on the top of the magnifier lens it fit right in place where the original Transformer magnifier lens is mounted without any modifications. Depending on how bad your close up eyesight is, you may be able to get away with using the included magnifier lens and just the extension.
Hope that this helps those who are looking for an inexpensive headset with HD resolution.
