How Competition Electronics ProTimer and ProChrono Models Differ

Competition Electronics splits its lineup into two jobs: shot timers (ProTimer BT, ProTimer) for measuring draw and split times in training, and ballistic chronographs (ProChrono DLX, ProChrono LTD) for measuring bullet velocity during load development. Within each pair, the only real dividing line is Bluetooth. The Bluetooth models cost more and add wireless app connectivity; the non-Bluetooth models keep the same core measurement hardware and accuracy for less money. All four are assembled by hand in Rockford, Illinois, and all four are listed as "Call to order" rather than online checkout.

Shot timers: ProTimer BT vs. ProTimer

The ProTimer BT is the model to pick if you want your string data on a phone. It pairs with the PTLink app, which is also where you get the free firmware update adding a countdown mode — press start and the display runs backward from your selected par time in real time. That par-time countdown is a training feature, not a scoring one.

The standard ProTimer goes the other direction: no Bluetooth, but it includes hit factor scoring, which is the metric USPSA-style competitors use to compare score against time. If you score matches or track hit factor in practice and don't need app sync, the ProTimer covers it for $30 less.

Both hold a 50-string memory. On the BT, those strings are time-stamped, which matters when you're reviewing a session after the fact rather than reading times off the screen between runs.

Chronographs: ProChrono DLX vs. ProChrono LTD

This pair is simpler. Competition Electronics states the LTD has every DLX feature and the same ±0.5% accuracy, minus Bluetooth. So the $20 difference buys you wireless connectivity only — the velocity measurements themselves are equivalent. Choose the DLX if you want to log or view shot strings on a phone at the bench; choose the LTD if you'll read results off the unit and don't want to pay for a radio you won't use.

How to decide

• Training with a shot timer, want app sync and time-stamped strings: ProTimer BT ($167.95).
• Training or match scoring, hit factor matters, no app needed: ProTimer ($137.95).
• Chronograph work, want phone connectivity: ProChrono DLX ($139.95).
• Chronograph work, screen readings are enough: ProChrono LTD ($119.95).

One accessory note: the DAA CE ProTimer silicone skin is $14.95, or free with any ProTimer or ProTimer BT — but only when purchased from Competition Electronics directly. Since every unit above is call-to-order, that's the same channel.

What the sponsored shooters say

The page quotes three sponsored competitors. Todd Jarrett, a multiple-time national and world champion, describes the ProTimer BT as providing "the feedback for a more effective training session at the range." Randi Rogers, winner of over 30 world and national titles, calls the ProTimer "accurate, easy to use" across many shooting types. Evil Roy, a cowboy action national and world champion, notes that every strong shooter he knows trains with a shot timer and rates these "the best of the breed." These are endorsements rather than measurements, so treat them as a signal about durability and usability in competition rather than a spec comparison.

Before you order

Prices and the call-to-order requirement come from the product listings on the site. The page does not state shipping terms, warranty length, or whether phone orders ship immediately, so confirm those when you call. Repairs and returns, dealer and distributor info, and a video library are linked from the site if you want documentation before deciding.
