Chesterfield claimed their second pre-season win in as many days as their attacking quality saw them beat Buxton 4-0 at Silverlands.
The breakthrough saw the Spireites take control of the contest and ahead of the break Jay O'Shea made it two, before Jake Orrell scored the third just after the interval. The Spireites' grip tightening, Mani Dieseruvwe grabbed a smart fourth with a low 20-yard drive.
Sam Clucas made his way down the left-hand side and put a low ball across the face of goal, which made its way towards Gardner who struck first-time but ultimately failed to hit the target.
Waiting inside the area, Gardner eventually connected with Sam Morsy's irresistible cross from the right-hand side and forced an extremely impressive save from Phil Barnes who then prepared to instigate a rare attack for the home side.
Moments later, Gboly Ariyibi fed the ball to the feet of O'Shea near the 18-yard line and the Irishman tried his luck only for his effort to avoid the post by a considerable distance.
With 25 minutes on the clock, the Spireites took the lead through an unlikely source in the form of Dan Jones as the left-back advanced towards goal before rifling the ball straight in the direction of Barnes, who fumbled the attempt into his own net.
In an advanced position, Morsy aimed to get in on the act with an ambitious attempt from distance, although the midfielder failed to trouble the opposing goalkeeper as the ball sailed high and over of the crossbar.
On 37 minutes, the Spireites doubled their advantage courtesy of O'Shea who evaded his marker and unleashed a thunderous effort from just inside the area that made its way past a flailing Barnes.
Just before the half-time whistle, substitute Jake Orrell received a short pass on the edge of the hosts' penalty area before turning and firing straight into the arms of Barnes.
Immediately after the break, Orrell added Chesterfield's third goal of the evening with a smart finish from close range after receiving an intricate pass from half-time substitute Armand Gnanduillet.
Involved once again, Orrell picked up possession on the edge of the area before turning and directing the ball wide of the post when he may have been expected to hit the target.
A driven cross from the right-hand side found the head of Mani Dieseruvwe, whose powerful effort was cleared off the line by an extremely alert member of the home side's defence.
On the hour mark, Dieseruvwe netted Chesterfield's fourth goal of the evening after his lone run culminated in a low shot that nestled in the bottom left-hand corner of the net and beat Barnes all-ends-up.
Ollie Banks then took matters into his own hands with an individual run that preceded a ferocious attempt from around 25 yards that sailed narrowly wide of the post with Barnes firmly rooted to the spot.
In the closing stages, Rai Simons attempted an overhead-kick near the penalty spot and directed the ball out of the stadium as the Spireites sealed a second consecuitve pre-season victory within the space of just two days.
