Does anyone know what the true weights of these coils are? Also what is the approximate difference in the depth between these two coils? I have the mxt 300 and after swinging this setup for about 4 or 5 hours it gets very tiring' I"m thinking about purchasing the 9.50 depending upon the outcome of this post . I "ve been reading these forums for months and decided to join. I"m the owner of two brands of machines and I enjoy them both . The MXT 300 is my primary search machine and it might be worthwhile for me to purchase one .My hunting is large fields up to several hundred acres . Thankyou for your information and opinions it is greatly appreciated!
