New for 2023 from Rocky Mountain Hunting Calls and Supplies! In collaboration with legendary call maker Rockie Jacobsen, we are introducing our newest, most innovative diaphragm to date.  The new NSU “Next Step Up” consists of a recessed latex and palate plate that places your tongue in the correct position, allowing the most novice user to understand how a diaphragm works. This is the easiest diaphragm on the market to use and fits the widest variety of palates. The original palate plate designed by Rockie Jacobsen brought a design to the market that has allowed those that have a gag reflex the ability to use a diaphragm by placing it further forward in the mouth. With the added NSU technology, it now has taken the guess work out of proper tongue placement.

172 – The Monarch is designed for people who have a “Medium Profile Palate Plate” which provides a more comfortable fit allowing for a more efficient use of the call. This call is a single latex and makes beautiful mature estrous cow sounds.

170 – The Moon Phase is designed for people who have a “Flatter Profile Palate Plate” which provides a more comfortable fit allowing for a more efficient use of the call. This call is a single latex and makes cow/calf sounds and spike to satellite bull sounds, built on a medium low profile advanced NSU frame.

171 – The Warrior is designed for people who have a “Medium Low Profile Palate Plate” which provides a more comfortable fit allowing for more efficient use of the call. This call is a single latex and makes cow/calf sounds and satellite to herd bull bugles, built on a medium mid-profile advanced NSU frame.
