If your concerned about the coil being too close to you, just extend the length of it so that its further away from your body, it shouldnt be a problem. Anyways, I realy hope you dont give up on this great hobby. I actually owe a great deal of credit to metal detecting for my own personal recovery because it got me outside and using my legs and getting the muscle memory working again and stuff like that. Back in May of 2006 at work I free fell 60 feet off a roof, compound fractured both femures and pancaked my right heal. Both of my femurs looked like your fracture, shatered and major gaps between the bones. So I spent a year in the wheelchair and because of this I lost all my muscles due to atrophy, so my doctor finally says,"lets get you weight bearing and see what happens" even though he could see only a little bone growth in both femures. So im walking around using a walker for the longest time.More bone growth is showing on the x-rays so now im using crutches and at this time im slowly starting to get back into detecting even though im using crutches.Even though I cant go to all these places id like to detect at like up a mountain or off into the woods I can still detect slowly at school yards etc...so as time passes on my mobility is getting better but still cant walk up the slightest incline like a wheelchair ramp for example. SO now ive progresed to a cane and my mobility is getting better and I found that even though ive did tons of physio in the gym that some of the best physio is just getting and doing walking out no matter how slow or awlkward it is because it will get better over time, it just takes time.So its been 2 3/4 years since my accident and im still getting better but I still cant run or jump but Im now detecting in all the places that I was going to before I fell off the roof, im going into the woods and up mountains etc...So I just want to say no matter how frustrating it can get at times with the pain or your lack of mobility just never give up and stay persistent and alow your body to get better slowly because a full recovery will not happen over night. I wish you all the best.
