Um it comes with a belt clip.....

 

Maybe I should have said " I don't like the belt clip" up front. looking for something to just tuck the transmitter in when my hands are busy doing other things, but easy access if I need it.

 

I am not sure if this is "bulky", but it might be worth looking at...

It looks like the coyote holster is for an edge vs an edge rt.

The only one that I found was at www.unionlevelleather.com. Note that some of the controls (pulse and on/off magnet) are not accessible when the unit is in the holster.

 

A pro 550 holster may work since they are similar in shape and size.

 

I hate the clip also. Always slipped off when I sat in a UTV. Tried several holsters including a 550 (bad fit), none were exactly what I wanted. While you might consider it too bulky, I finally went with a Klien tool belt flashlight holder. Had to very slightly and easily stretch it (soaked in water and used a sunscreen spray can that just happened to be the perfect size)a tiny bit for the very light friction fit I wanted. Now easily slips in and pulls out but doesn't come out unintentionally.
