If it's an Omnex remote already, then I would imagine they could clone one of their hand-held models to work with the receiver.

while at the Con Expo I asked the HBC group about a small easy remote. The Patrol S Is quite compact and has 4 toggle switches and e-stop, looked like it would fit on a belt easy and fits in hand well.Take a look on the web site. I will get Pics later http://www.hbc-usa.com/en/Products/fwe-patrol-S-Forestry-applications.html

Ds it is no problem , ask the same manufactuer you have on the "big" remote . It is like TravelT says , HBC who make Putz remote has a Swedish dealer who has build a "little" remote with pump on , pump revers , pump off , rpm and volyme . For job with "only" hose . Like a remote to trailerpump.

Yes it can be adapted for Trailer pump I spoke to the HBC Reps at Con Expo and they said no problem. Call or e-mail Hector Sanchez 800 410 4562 x 104 hsanchez@hbc-usa.com Hector should recall talking with me. Tell him Alan Woods with Putzmeister asked him about this at the show

This is the remote they were suggesting.

Dipstick tell your boss the main remote will last much longer. The big box will become messy when you work with lines every day. Ask your mate Ferry to take a pic for example. His remote has been in repair several times, because the joystick rubbers don’t last for a long time
