Has to be the PPer. It allows you to almost hunt like a PI.... with the advantage of flipping to disc to check a target. Speeds up hunting, increases the amount of sand you can cover in a hunt, allows for better sizing of the target, and there is no recovery time over targets when in PP. In PP a good pair of upgraded phones really increase what you hear without blowing your ears off like in disc. Joes use of the CTX connector makes it simple to swap those phones or just by another pair that fits the CTX. Also...... those 1600 Mah Maxxpac batteries are a top notch upgrade with long life and fast charge.... oh, and they have a dang light on the charger. Shafts...... CF has increased our ability to better balance the machine and reduce the weight.
I like Joes idea of coil swapping as well thats he testing. The CTX connectors seem to work, but id like to have a coupler where i can use the coil on both a Sov and the Xcal instead or one or the other. I take my hat off to you Joe...... you have really brought out the Xcals potential. Im hoping for a STANDARD waterproof connector that all the companies will use in the future for headphones. Id like to get away from hardwire phones and coils. I think thats the only way we are going to get improved headphones and coils. With the Sov gone its just not profitable any longer to research and inprove its coils.
