  • 1201149358?profile=original?width=7501201149389?profile=original?width=7501201149485?profile=original?width=750Some pics of my HP48 with a protective "custom" leather-vinil-film cover and an adapted cable to connect directly to a Trimble total station, I can use it as a TS controller, data collector or handheld calculator (lot of help of the hp forum to do this).

    The back straps allow to hang the calc in a tripod "hands free mode".

    Glad to share my surveyor-inventor moments with you jajaa.
