Hey im new to archery and having a hard time finding a good compound bow for myself, i was wondering if you have any suggestions as to good used models to look for and affordable newer ones to look into,

Im 6 ft 9in, 75in arm span, can comfortably handle 70 pound draw weight, also want something with over a 34" Axle to Axle length, planning on using for hunting deer. working with $500 to $800 budget any help is greatly appreciated.

id say your best bet would be go to the local bowshop if you have one

Bowtech sentinal is a good bow adjustible draw lenght 2010 has flx gard and found mine on ebay for a real good price. Smooth and quite long axcel to axcel veary steady and acurate.

I agree. Go to your local PROSHOP (not a Bass Pro) and have them fit you. You are gonna have a hell of a draw length. Definatly get over a 34 inch ATA bow. Look at The Hoyt Maxis 35. Awesome bow. Quiet, smooth, and very accurate. Give it a look and I guarantee you wont be dissappointed.
Good Luck,

Take a look at a Hoyt Katera XL. They can be picked up at a good price.
